Title: Improvements relating to the remote control of television receivers
IPC: H04B1/16
Filed: 1961-01-06
Abstract: 928,036. Remote control of television receivers. E. K. COLE Ltd., E. C. W. FIELDER, and N. L. ALLEN. Dec. 28, 1961 [Jan. 6, 1961], No. 586/61. Class 40 (3). The invention relates to a remote control system for altering the tuning of a television receiver by a light beam. As shown a lightsensitive resistor P mounted in the front panel of a television receiver is connected in a circuit controlling a relay RL having contacts RL1 which operate an electric motor driving a turret tuner (not shown). Initially a triode V1 is conducting while a triode V2 is biased beyond cutoff. A light flash for instance from a beam of a remote electric torch passing across the resistor P produces a negative pulse on the grid of V1 causing it to be biased towards cut-off with a subsequent rise in anode voltage, producing a charge on capacitors C4, C5 and C6. The voltage on the grid of V2 due to one pulse is arranged to be insufficient to operate the relay RL, by selection of the values of the capacitors C4, C5, C6 and resistors R4 and R5. After a pulse C4 discharges through V1 and a diode V4, a further diode V3 cuts off, C5 and C6 retaining substantially the whole of their charge which is integrated with charges received from successive pulses. A predetermined number of pulses produced by waving the torch across the resistor thus integrated raise the grid of V2 to a potential at which the relay RL will be caused to operate, closing contacts RL1 and operating the turret through the motor, and operating further contacts RL2 and RL3 which short the output of V1 to earth, break the contact between C5 and C6 and short-circuit C6. C5 then discharges through a resistor R6 causing the anode current to fall until the relay RL is deenergized and preparing the circuit for a further train of pulses. To assist an operator in aiming the torch at the resistor P, a reflector or other such guides may be provided round the resistor. The receiver may have its volume control operated by a similar system or systems.

Title: Improvements in sliding clasp fastenings
IPC: A44B19/04
Filed: 1928-01-09
Abstract: 283,465. Rahmig, C. L. Jan. 7, 1927, [Convention date]. Sliding-clasp fastenings. - In a sliding-clasp fastener for the edges of flexible material a each of the interengaging members has a cylindrical head b with its axis transverse to the edge of the material, and two pointed jaws c adapted to be pressed into opposite faces of the material in the usual way. Each head has a groove d adapted, when the members are in interlocked position, to engage the edge of the opposite piece of material, which may be reinforced by a wire &c. g. This construction prevents lateral displacement of the interlocked members and allows a closer approximation of the edges of the material so that the gap is wholly covered by the heads b. The fastening is controlled by a slider h in the usual way, and to facilitate entry of the interengaging members the slider is outwardly flared at i, as seen in side view of the slider, Fig. 5.

Milling-machines; milling screws, -- Relates to the avoidance of facets on work rotating synchronously with the cutter, and consists of a special arrangement of gearing whereby the hob or cutter is caused to gain and lose on the work alternately during automatically-controlled periods. The gearing is such that there is no relative axial movement between the hob and the work. The spindle 1 which drives the work carries fast gears 2, 3 and close gears 6, 7. The gear 6 has more teeth than the gear 2, and the gear 7 less teeth than the gear 3. The pairs of gears are connected by the idlers 5, 4. A pinion 8 loose on the shaft is clutched alternately to the gears 6, 7 and is geared to the hob spindle. The clutch pinion is shifted by a lever 14 rigidly connected to a lever 30 and carrying a pin engaging a slot in a sector 19 wormdriven from a pinion 18 meshing with a pinion 32. When the end of the slot engages the pin, the clutch pinion is given a quick throw-over. At the same time, a clutch 27 is thrown over, reversing the pinion 32 and consequently the sector. The clutch 27 connects the pinion 32 alternately to gears 26, 25 meshing respectively with the gears 2, 4. Specifications 14571/15 and 16679/15 are referred to.

Patent JP-S58117719-A (JP)
Title: Automatic threshold value set circuit
Inventor: OONISHI MAKOTO
IPC: H04L25/03
Filed: 1982-01-06
Abstract: PURPOSE:To reduce the leakage current and an error voltage, by dividing a peak voltage of a received input signal with capacitors, taking a voltage divided point as a threshold value of a comparator and excluding the resistive component. CONSTITUTION:An input voltage Vi passes through a diode 4, charges up capacitors 6, 7 connected in series and keeps the peak of the input voltage. This peak value is divided with the capacitors 6, 7 as the threshold value of the comparator 1. Since the voltage division is done at the capacitors, a discharge time constant is taken very large and no buffer amplifier is required. Further, the peak value keeping and the voltage division are done with the same capacitors, allowing to reduce the number of components.

Title: Mold for optical element
Inventor: HIJINO MASAMICHI
IPC: C03B40/02
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To obtain the subject mold high in hardness, good in releasability for glass, and hard to develop film debonding, thus high in durability, by forming a chromium nitride layer at least on the molding surface of a mold matrix to be used for press molding of a glass optical element followed by oxygen ion implantation into the layer to convert at least the surface to a chromium oxide layer. SOLUTION: A chromium nitride layer is formed at least on the molding surface 3 of a mold matrix 2 by e.g. ion beam sputtering technique followed by oxygen ion implantation pref. at 0.01-1Lμm in ion penetration depth and at 1×10<15> to 1×10<19> ions/cm<2> in quantity into the chromium nitride layer to convert at least the surface to a chromium oxide layer. As a result, the chromium oxide layer has such a characteristic that oxygen density is distributed gradient-fashion so as to gradually decrease from the molding surface toward the direction of depth, and there is no interface between the chromium oxide layer and the chromium nitride layer, thus affording firm adhesion therebetween.

IPC: A01C11/02
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To solve the disadvantages such as the occurrence of the change of planting depth even by a local unevenness and the difficulties in the arrangement of a vertical motion-controlling system in the space where devices such as wheels and a mission case are complicatedly placed, while holding the structure using right and left floats as stands. SOLUTION: This single-wheel walking-type rice transplanter is provided with a vertical motion-controlling mechanism 35 for constantly keeping planting depth by the vertical motion of the single-wheel 10 according to the variation of grounding pressures of right and left floats. In this rice transplanter, the vertical motion-controlling mechanism 35 is composed of a mechanical vertical motion-controlling system in which a vertical-motion controlling valve 15 and an operator-side operating rod 21 are mechanically linked to each other, so that it can take three states consisting of a vertical motion-controlling state for keeping planting depth at a constant level,  a neutrally locked state for enabling the keeping of the self-standing posture of a machine body by fixing right and left floats at a relatively low position against the wheel 10 and a forcibly lifted state for fixing the right and left floats at a relatively high position against the wheel 10 and suitable for mobile running.

Title: Re-editing device for still picture recorder
Inventor: ARAKAWA HIROAKI
IPC: G11B27/02
Filed: 1988-01-07
Abstract: PURPOSE:To perform the re-edit of an image by filling the image in sequence of track number by erasing the record content of a recorded track after storing the record content of the recorded track at the next position of a detected unrecorded track in a memory, and writing the storage content of the memory on the unrecorded track. CONSTITUTION:When the unrecorded track on a magnetic disk 1 is detected, the recorded track at the next position of the unrecorded track is detected, and the record content of the recorded track is read and transferred to the memory 16, then, it is stored in the memory transiently. And the record content of the recorded track is erased, and the storage content of the memory 16 is written and re-recorded on the unrecorded track. In such a way, it is possible to perform the re-editing of the image recorded on a recorded magnetic disk set in a state where a part of the disk becomes the unrecorded track by erasure, so-called a toothless state, by filling in sequence of the track number.

Title: Manufacture of seamless steel tube by hot extrusion
Inventor: MATSUO HIROSHI
IPC: B21C23/32
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To manufacture a seamless hot extruding tube having few seiqure and few variation of the outer diameter pn the axial direction by using a hollow billet of, by Rmax, 30-100μm in the surface roughness as the extruding stock. SOLUTION: When uniform and fine micropools are formed by applying e.g. satin treatment on the inner and outer surface of the hollow billet B, a glass and lubricant disk 8 coated before putting them into a container 1 are sealed and stored at the early stage of plastic deformation in the hollow billet B, and introduced into the working section. As the surface area of the hollow billet B is enlarged in the working section, the glass is exposed on the surface of the hollow billet B and subjected to surely and continuously and stably act as the lubricating film. Even if working is performed e.g. at the extruding ratio of 40 or more, the film thickness of lubricating glass is not extremely thinned, adiabatic effect is improved, and wear and deformation are restrained.  By this way, the extruded tube having few seizure and few variation of the outer diameter in the axial direction is manufactured.

Title: Optical transmission system
Inventor: INOUE YASUSHI
IPC: H04B10/58
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To minimize the peak value of signal waveform distortion in an optical transmission system using a semiconductor optical amplifier by transmitting signals by specifying the light intensity of signal light to be turned on/off within a specific range. SOLUTION: When a one-bit length is defined as T, light intensity P in the ON state of signal light is defined as P0 /2 on the conditions of 0<=t<T/4 and 3T/4<=t<T and P0 on the condition of T/4<=t<3T/4 and the light intensity in the OFF state of signal light is defined as P0 /2 on the conditions of 0<=t<T/4 and 3T/4<=t<T and 0 on the condition of T/4<=t<3T/4. In this case, (t) is the time and P0 is a constant expressing light intensity. When storing signal light is inputted to the semiconductor optical amplifier, carrier density is fluctuated with a prescribed time constant. Then, even when the same code is continued, light intensity is surely switched within one time slot so that the peak value of distortion can be reduced.

Abstract: A data processing system has files stored on disks in a tree structure of directories and files. The system is operated to rapidly open files which have been recently opened or for which partial path information is available, by accessing a drive cache (30) in main memory (16). The cache has entries chained in a tree structure which is then searched to provide the same information during the opening process as that information which would otherwise have to be obtained from a disk (22). When the cache is full, a new entry replaces the least recently used entry.
