Title: Treating device for head lead wire
Inventor: ISHIOKA KIYOSHI
IPC: G11B5/54
Filed: 1985-01-24
Abstract: PURPOSE:To prevent a lead wire from twisting and twining by providing a collar part and a head base which has a lead wire clamping member at a position corresponding to the lead-wire clamping cut of a head rotating support bearing member. CONSTITUTION:The lead wire 20 wound in the gap between a head rotary plate 4 and the collar part 7b is run through the gap 12h between lead clampers 12f and 12g. Then, when the head rotating support bearing plate 9 is fitted to the head base 12, end surfaces 9d and 9e of the clamping hole 9c on the receiving plate 9 presses slanting surfaces 12i and 12j of the lead wire clampers 12f and 12g inward to narrow down the gap 12h eventually, thereby clamping the lead wire 20. Consequently, the twisting of the lead wire is prevented and even if the lead wire has a slack at a lead-wire winding-up part, the collar part 7b is prevented from moving below the collar part to prevent the lead wire from twining with other members in a head clock.

Title: Four-terminal measuring instrument
Inventor: KITAYOSHI HITOSHI
IPC: G01R27/26
Filed: 1989-01-19
Abstract: PURPOSE:To accurately measure the voltage across a body to be measured without damaging an element for measurement by detecting conduction between 1st and 3rd contactors and 2nd and 4th contactors, and detecting whether or not there is a potential difference between specific contactors. CONSTITUTION:When the resistance between the 1st and 3rd contactors 13 and 18 decreases, a large current flows to the secondary side of a transformer 32, and consequently the potential at the contact 38 rises and the output of an inverter 39 varies from high level to low level. Similarly, when the resistance between the 2nd and 4th contactors 16 and 19 decreases, the output of an inverter 46 varies to the low level as well. Consequently, the conduction between the respective contactors is detected. Further, when there is any potential difference between at least two of the contactors 13, 16, 18, and 19 coming into contact with electrodes 12 and 15 of the body 1 to be measured, the potential at a contact point 61 rises and a transistor 62 turns on the cause variation of the output of the inverter 62 from the low level to the high level, so a high voltage developed between contactors can be detected before four-terminal contacting, and a signal source 14, a current-voltage converter 17, buffer amplifiers 21 and 22 for voltage detection, etc., are prevented from damaging.

Abstract: PURPOSE:To obtain a signal with broad band and excellent stability by applying clamping close to an ideal operation by providing an input buffer circuit with a low output impedance and a DC amplifier circuit applying capacitor coupling and receiving an input signal without DC component by the AC coupling circuit. CONSTITUTION:The DC amplifier circuit 114 has the structure such that FETs 1, 2 are connected in parallel, an input signal is given to the gate of the FET 1 and a feedback signal is given to the gate of the FET 2. Thus, the input signal and the feedback path are separated and the feedback quantity is set optionally. Moreover, the gate-drain of the FET 1 is intrisically insulated.

Title: Braking force controlling device for vehicle provided with starting clutch
Inventor: MURATA KIYOHITO
IPC: B60W10/184
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To certainly prevent a vehicle making a standing start on a slope from moving back by bestowing braking force on the vehicle regardless of brake operation by a driver and keeping the braking force until it is detected that the driving force is changed to a magnified condition. SOLUTION: When the brake is applied, the engaging force of a starting clutch 116 is controlled and returned so that the driving force may be weak. When the brake is not applied, the engaging force of the starting clutch 116 is controlled so that the driving force may be strong. Detection that the driving force is strong directly measures the oil pressure of the starting clutch 116 by a clutch oil pressure sensor 130. When the driving force is not strong, the braking force is kept by control of a TRC. When it is detected that the driver has stepped on the brake pedal 10 again, it returns to the normal controlling condition as the driving force being weak. When the driving force becomes strong, brake pressure is released by the control of the TRC and is in the condition of not having the brake applied. Thus a vehicle starting on a slope can be prevented from moving back.

Title: Gamma compensating circuit
Inventor: SUGIMOTO YASUHIRO
IPC: H04N5/202
Filed: 1982-01-29
Abstract: PURPOSE:To obtain a gamma compensating circuit with which the output level has no change by the gamma value and at the same time the gamma value can be changed consecutively with a simple control, by adding a signal received the gamma compensation and a signal received no gamma compensation together  through an adder circuit of a double balance constitution and with an adding  ratio corresponding to the control voltage. CONSTITUTION:There is a big difference of output level between a signal delivered from a buffer circuit 22 and received no gamma compensation and a signal delivered from a buffer circuit 33 and received the gamma compensation. Here an adder circuit 35 has a gain R35/R32 to the output signal of a buffer circuit 32; while the gain of the circuit 35 is R35/R34 to the output signal of the circuit 33 respectively. Thus both signals can be added together while the output levels of the buffer circuits 32 and 33 are coincident with each other by setting each resistance value. As a result, the output level can always be kept at a constant value with no effect given from the gamma value.
