IPC: H03M13/00
Filed: 1979-05-31
Abstract: PURPOSE:To increase the ability of detection or the like without increasing the number of steps of feedback shift registers, by outputting the output of the first and second parity bit generating circuits from the logical sum gate in series sequentially. CONSTITUTION:An parity bit generating circuit 30 is composed of (n-k) stages of feedback shift registers having generating polynominal g1(x), and from the input information m(x) in 4 bits input to the feedback shift registers, the parity bit r1(x) in n-4 bits having the relation of equation (1) is produced. On the other hand, the parity bit generating circuit 70 is composed of the n-k stages of the feedback shift registers having the generation polynominal g-1(x) which is reciprocal to g1(x), and the parity bit r-1(x) in n-k bits relating to equation (2) is produced from the coding data serial in n bits consisting of the input information in k bits and the parity bit r1(x) in n-k bits, and the output of the circuits 30 and 70 is output serially from the gate 90 sequentially. Thus, the number of stages of the feedback shift registers is not increased, allowing to increase the ability of detection or the like.

IPC: H01L21/302
Filed: 1988-03-22
Abstract: PURPOSE:To improve pattern formation accuracy by preventing variations of a processed line width from being produced by measuring an occupation area of a photoresist on a substrate and adjusting conditions of dry etching based upon a measured result. CONSTITUTION:An occupation area of a photoresist formed on a substrate conveyed by a substrate conveyor mechanism 1 is measured by a photoresist area measuring part 3, and a measured result is sent to an etching condition controlling computer 4 together with information concerning the number of mounted substrates. Then, the etching condition controlling computer 4 determines optimum etching conditions in conformity with a previously inputted rule, which are then sent to an etching chamber 2. Hereby, the substrate automatically mounted in the etching chamber 2 is etched following the optimum etching conditions. As a result, variations of a processed line width due to a change in a line width shift are avoided, thereby assuring good accuracy pattern formation.

Title: Disk rotating machine with magnet
Inventor: TANAKA YOSHIRO
IPC: H01L21/027
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To obtain a mechanism in which a disk with a permanent magnet is rotated by a mutual action of the permanent magnet and an electromagnet and a simple construction is provided so as to be easily made and smoothly, continuously rotated at high speeds and in which rotational speeds can be varied in a non-step manner and moreover a simple motor whose performance can be maintained for a long time can be made. SOLUTION: Several permanent magnets are attached to the periphery of a circular plate (disk) of thick paper or plastics to form a rotor 1 which is rotated by a mutual action between the magnets and an electromagnet. In that case, magnetic forces of the electromagnet is controlled by utilizing a lead switch 4 which acts by sensing magnetism, whereby the rotor is rotated while the timing of the mutual action of magnetism is being maintained. As a result, high speed rotation can be smoothly maintained so that a simple motor whose rotational speeds can be varied in a non-stop manner can be made. And an ON/OFF operation of the electromagnet effected by turning on or turning off the lead switch can be visually checked.

Title: Manufacture of optical fiber type optical branching and coupling device
Inventor: TAKASAKI SEIICHI
IPC: G02B6/28
Filed: 1992-02-20
Abstract: PURPOSE:To manufacture the optical fiber type optical branching and coupling device of invariably constant quality whose branching ratio has small wavelength dependency efficiently and stably at high yield without depending upon the skillfulness of an operator. CONSTITUTION:When both optical fibers f1 and f2 are spliced by fusion and drawn, monitor light having specific wavelength is made incident on the input side of the optical fiber f2 from a light source 100, and the output-side light output of at least one optical fiber is detected by a detecting means 104 and converted into an electric signal. Light which is used for the manufactured optical branching and coupling device, namely, has 1.65mum wavelength longer than 1.30-1.55mum is used as the monitor light. When it is observed that a peak C is reached while the variation curve of the branching ratio of the monitor light with 1.65mum wavelength is monitored, a drawing operation stop signal is sent out at the point of time when the branching ratio decreases by  P, i.e., 2% and after a heating device for fusion drawing is retracted, the rack- pinion mechanism of a fusion drawing table 102 is stopped.

Title: Rotor for permanent-magnet type synchronous motor
Inventor: SASAMOTO HISAYA
IPC: H02K1/27
Filed: 1981-05-11
Abstract: PURPOSE:To improve both operational and starting characteristics for the subject rotor by a method wherein a cage-shaped conductor and a permanent magnet are arranged on the outer circumferential surface of a rotor core, and the ratio of the void length g1 of the rotor core and the stator core located between adjoining poles and the void length g2 of the rotor core and the stator core within a pole is set at g2/f1>1. CONSTITUTION:A plurality of permanent magnets 3 per pole are arranged on the outer circumferential surface of the rotor core 1 and the cage-shaped conductor 2 is arranged in the core section located between the permanent magnets 3. For the rotor core 1, when the void length between core section located between the adjoining poles (on q-axis) of the rotor and the stator core 7 is set at g1 and the void length between the core section located between the permanent magnets (on d-axis) in a pole and a stator core 7 is set at g2, the outside diameter of the core section on the d-axis is formed a little smaller than the outside diameter of the core section on the q-axis. Accordingly, the coefficient of utilization of magnetic flux can be improved because the leakage flux coming from the N pole and reaching the S pole is reduced without breaking the stator winding.

Title: Optical intensity control method in optical scanning system
Inventor: NAKAJIMA TOMOHIRO
IPC: G02B26/10
Filed: 1986-03-27
Abstract: PURPOSE:To realize the light intensity for always correct optical scanning regardless of temperature rise or deterioration with the lapse of time by obtaining a correction voltage corresponding to a picture scanning clock frequency whose frequency is changed continously in response to the change in the scanning speed. CONSTITUTION:The reference value of the lighting intensity of a semiconductor laser 10 is set automatically by a reference signal from an output strength control circuit. A correction voltage Vc obtained from a picture scanning clock frequency control circuit 38 corresponds to a frequency of a picture scanning clock and is changed in response to the scanning speed. Thus, the variation of the I/P characteristic of the semiconductor laser 10 gives on effect to the correction voltage. Even if the I-P characteristic of the laser 10 is varied in case the scanning speed is an optional value in the speed region, the light intensity of the semiconductor laser is unchanged substantially.

Title: Wheels series of hand type portable watch
Inventor: YAMADA TAKEHIDE
IPC: G04B27/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To realize a structure with high practicality of hand correction mechanism correcting second without using slide mechanism by releasing the gear of a pinion of wheel when an outer operating member is operated. SOLUTION: When an outer operating member is operated to be in second correction state, the gearing of only pinion 3b of the third wheel is released. By this, the tops of gearing of gears is prevented from interfering and causing skip of hands in the process in which the third wheel becomes gearing state again after hand correction. That is, by removing the gearing of the pinion 3b of the third wheel and the gear 5a of the second wheel, skip of hand of fourth wheel does not generate. The skip of minute hand caused by the shift of circumferential pitch between the third pinion 3b and the second gear is suppressed in a small range because the outer circle of the second gear is large. As the correction of hour hand can be done with almost no load, the wheel series and the surrounding members relating to the correction needs little strength and thus cheap plastics material can be used.
