Title: Data processing method of multiple address repeating device
Inventor: MATSUKA TETSUYUKI
IPC: H04L29/02
Filed: 1981-12-29
Abstract: PURPOSE:To simplify the circuit constitution of a multiple address repeating device by adding ineffective data consisting of >=(n) bits behind the ending part of data and performing (n)-bit multiple-address repeating processing. CONSTITUTION:A flag detection part 71 detects the flag pattern of data on a path A to outputs a signal for showing that the data is on the path A to an ineffective-data added signal generation part 72. The circuit 72 counts the number of bits of the data and outputs a control signal for adding ineffective data at specific intervals of (n), e.g. 8 bits to an ineffective data addition part 73. Every time the control signal from the circuit 72 is inputted, the addition part 73 adds the ineffective data to the data on the path A to output data whose total bit numer is a multiple of 8. This processing method allows (n)-bit, i.e. 8-bit multiple-address repeating processing to simplify the circuit constitution of the multiple-address repeating device.

Title: Burst modulation wave control system
Inventor: MORISHITA KATSUJI
IPC: H03F1/02
Filed: 1990-08-10
Abstract: PURPOSE:To obtain a burst modulation wave whose leakage power is sufficiently attenuated from an amplifier by providing an APC circuit to a high frequency power amplifier and giving an APC voltage to the APC circuit so as to control the gain of the high frequency power amplifier in response to the APC voltage. CONSTITUTION:A power whose voltage is nearly 0V is inputted to a waveform generating circuit 12 as a burst control signal. The circuit 12 outputs an APC voltage corresponding to the burst control signal to an APC circuit 11 of a high frequency power amplifier 10 as it is and since the APC voltage is nearly 0V, the output power of the amplifier 10 is minimized and the gain is reduced. The circuit 11 is able to attenuate the output power of the high frequency power amplifier 10 by 30dB or over and when the burst control signal is not set, leakage power is sufficiently attenuated. Since the circuit 11 controls a drain or collector voltage of a FET or a transistor of the amplifier 10 uniformly, when the burst control signal is not set, no drain or collector current flows and the power is not almost consumed.

Abstract: PURPOSE:To double the durability performance of an engine by housing an inner cylinder eccentrically in an outer cylinder so as to form a durable structure by means of a support member interposed between the outer surface of the inner cylinder and the inner surface of the outer cylinder at the position where both cylinders are farthest from each other. CONSTITUTION:An inner cylinder 2 is eccentrically housed in an outer cylinder 1 and a support member is interposed by utilizing the spot where both cylinders are farthest from each other. Accordingly, the stain of rubber on the surface becomes smaller than that on the case of concentric arrangement because of longer support member 3 when the inner cylinder 2 makes vibration in the direction for applying shearing deformation to the support member 3, and the support member 3 can be formed in thick layer even up to the bonded part. Thus, the durability performance can be doubted.

Title: Overcurrent protective circuit for switching regulator
Inventor: KOSEKI KATSUHIKO
IPC: H02M3/28
Filed: 1990-08-14
Abstract: PURPOSE:To protect overcurrent properly when a load is either static or dynamic, by outputting an overcurrent protection signal when detected voltage induced in the secondary winding of a current transformer exceeds threshold voltage based on a load condition signal inputted. CONSTITUTION:When a load condition signal DP is at a LOW level, a circuit operates at a low range similar to a conventional overcurrent protective circuit. When the load condition signal DP is at a HIGH level, the load condition signal DP becomes larger than reference voltage V2, and the output of a comparator IC2 is opened. Besides, voltage V3 on this occasion is made higher than (divided voltage of resistors R3 and R4 + forward voltage drop VD4 of a diode D4) by selection. Accordingly, the diode D4 is biased in the forward direction, and threshold voltage Vf is lowered up to voltage V3-VD4. This makes the difference (margin) between the threshold voltage Vf and detected divided voltage V1 large, and switching action is continued without detecting overcurrent even if overloaded to some extent.

Filed: 1984-10-12
Abstract: PURPOSE:To prevent developing liquid shaked off from a rotating wafer to be dried from re-depositing onto the wafer, by providing with a plural of slant plates which enclose a spin chuck in a developing apparatus. CONSTITUTION:A semiconductor wafer 1 is mounted on a spin chuck 2 in a developing apparatus, and photo resist on the wafer 1 is developed by developing liquid sprayed from a developing nozzle. After finishing the developing, the wafer 1 as well as the spin chuck 2 is rotated 10 fast to shake off the developing liquid to dry the wafer 1. A plural of slant plates 8 which enclose the spin shuck 2 are mounted to the upper cap of the developing cup. In this way, the developing liquid shaked off from the wafer 1 due to the fast revolution 10 bumps against the slant plates 8 and flys away from the wafer 1 downward as shown in the loci 9. Thus it is prevented that the developing liquid may reflect at the inner wall of the cup 4 and may re-deposite onto the wafer 1.
