Title: Record disk reproducer
Inventor: ONO TSUYOSHI
IPC: G11B21/08
Filed: 1982-09-21
Abstract: PURPOSE:To shift a tone arm at a high speed and to ensure stable and assured follow-up of the arm in a play mode, by increasing the minimum unit of the count change degree of a counting means when the arm is shifted at a high speed and changing the minimum unit to a small level in a play mode to drive a step motor. CONSTITUTION:A system control circuit 18 supplies different control signals for count change degree to a counter circuit 172 between a high-speed shift mode and a play mode of a tone arm 1. A comparator 14 compares the count number at the arm position given from a counter circuit 171 with the count number at the lead-in position given from a target storing circuit 13. Then an indication signal is delivered to the circuit 172 from the circuit 18 so as to set the error value at zero, and a motor 16 is driven. The arm 1 reaches quickly its target position since the minimum unit of the count change degree is switched to a large value in a high-speed shift mode of the arm. The miniumum unit is then changed to a small value in a play mode. This ensures stable follow-up for the arm 1 with high S/N.

Abstract: PROBLEM TO BE SOLVED: To eliminate an odd feel and oppression feel and to prevent a sound leaking phenomenon by injecting a flexible, curable ear mold material into the auditory canal, performing this material, cutting its front end, applying an ear mold material more flexible than the material described above between first and second curvilinear parts, again inserting the material into the auditory canal and curing the material. SOLUTION: A flexible, curable ear mold material 4 consisting of silicone material is injected into the auditory canal 1 by a syringe for insertion. At this time, the injection is carried by passing cotton 3 with yarn for preventing the pushing-in of the ear mold material through the material so as to prevent the pushing-in of the ear mold material into the tympanic membrane 2. After the material is cured, the material is taken out together with the cotton 3 for preventing the pushing-in of the ear mold material by pulling the yarn, by which a preformed ear impression is obtained. The front end near the depth of the ear, i.e., the portion spreading deep from the tip of the second curvilinear part 7 near the tympanic membrane is cut.  The material which is more flexible than the ear mold material 4 is then applied near the portion corresponding to the second curvilinear part 7 from the first curvilinear part 8 and is again inserted into the auditory canal 1 and is cured. As a result, the impression adapts itself into the external ear and the odd feel and oppression feel may be eliminated.

Title: Thyristor or triac with emitter short-circuit band
Inventor: JIYAN PORU NAJI
IPC: H01L29/747
Filed: 1988-07-04
Abstract: PURPOSE: To optimize the triggering and inhibiting features of a triac AC switch by collecting emitter short circuits which come into contact with emitter metallization in a zone extended through the surface of an emitter area and adjusting the ratio between the surface in which the emitter short-circuits in zones are collected and the surfaces of the zones to a specific value or larger. CONSTITUTION: An emitter short-circuiting hole is formed of two zones 30 and 32 on the front face of a triac AC switch and two zones 34 and 36 on the rear surface of the switch. Although the triggering performance of a thyristor is improved by the hole, it is preferable to form the zone 30 so that the zone 30 can be extended closely to the boundary area between surface areas N and P which come into contact with each other at the metallization 18 on the front face so as to simplify the extraction of charges when the thyristor is switched off. On the rear surface of the switch, the zones are arranged similarly to the zones 30 and 32 arranged on the front face. The ratio between the integral surface of the short-circuiting hole in the zones and the surfaces of the zones is adjusted to at least 30%.

Title: Gain controller
Inventor: OONISHI MASAMI
IPC: H03G3/20
Filed: 1981-10-15
Abstract: PURPOSE:To turn the output of an automatic gain control (AGC) circuit into an optimum level in response to the state of an input signal, by having a peak mean value AGC action when an object to be picked up is bright and a peak AGC action when the object to be picked up is dark respectively. CONSTITUTION:When an object to be picked up is bright, the signal (a) is compared through a comparator 8 with the voltage V110 that is set at one-to-an- integer level of a standard input signal via a mean value detector 6. As a result, it is decided that the level of the signal (a) is higher than the voltage V110. Thus the output of the comparator 8 is set at 0, and a comparator 7 is inactive. Then an AGC circuit 4 starts its working. When the object to be picked up is dark, the output of the comparator 6 is less than the voltage V110. Thus the output of the comparator 8 is set at 1, and the comparator is active. However the output of the detector 6 is set lower than the voltage V29 which is set at the peak value obtained during an appropriate input signal. As a result, the output of the comparator 7 is set at 0 and the circuit 4 works. When a bright spot exists in the dark, both comparators 7 and 8 work. Then the comparator 7 delivers the positive. This voltage is added with the output of a detecting circuit 42 in the form of the external control voltage of the circuit 4.

Title: S/n switching system
Inventor: HIKOSAKA KOUJIROU
IPC: H04W36/38
Filed: 1984-08-07
Abstract: PURPOSE:To attain efficient S/N switching while simplifying the constitution and improving the profitability by allowing a control station to compare S/N information transmitted from each party via a transmission line so as to switch selectively the transmission line. CONSTITUTION:The control station C compares the S/N information transmitted from approach lines D1, D2, selects the approach line D1 or D2 of the better S/N and gives it to an output terminal E. The S/N information corresponds to the preset electric field information or the S/N and is transmitted in parallel with an output from a base station. Since the base stations are connected at an interval of one station, when the S/N information of e.g., the base station B1 exists, the base station B3 has a value below the set value on the line, then the output is interrupted completely. Thus, no interference between the base stations B1 and B3 exists, and any technology such as phase equalization of the approach lines is not required at all.
