Title: Variable constant type chirp signal generating circuit
Inventor: ICHIYOSHI OSAMU
IPC: G01S7/28
Filed: 1987-06-30
Abstract: PURPOSE:To easily generate a variable chirp signal by setting a chirp rate and signal time length independently by setting the constant of a constant generator and the initial value of a digital integrator with output pulses of a counter. CONSTITUTION:The constant generated by the constant generator 15 is integrated twice through digital integrators 20-1 and 20-2 to obtain a phase signal as a secondary time function. This phase signal is inputted to ROMs 5 and 6, whose outputs are passed through D/A converters 7 and 8 to obtain complex chirp signals of the base band consisting of COS chirp signals and SIN chirp signals. Those signals are passed through mixers 11 and 12 and a signal composing device 13 to obtain a chirp signal of the IF or RF band. The chirp rate is obtained according to a numeral set in the constant generator 15 and the optional time length is obtained from the frequency division ratio of a counter 2 where the initial values of memories 4 and 17 of the integrators 20-1 and 20-2 are set.

Title: Drag preventive device of wet type clutch
Inventor: DOI FUMIO
IPC: F16D48/02
Filed: 1982-09-17
Abstract: PURPOSE:To improve drag preventive effect and minimize the clutch fitting time by making the gap between friction plates adjustable from the outside. CONSTITUTION:Besides a main hydraulic piston 7, an auxiliary hydraulic piston 10 is provided in an operating cylinder 8, and operating oil supply passages 11 and 12 which operate these pistons while pressing a return spring 9, are provided therein. A hydraulic changeover valve 15 which communicates or closes these passages, is also interposed therein. When the operating oil has a high temperature, the operating oil communicates with the operating oil supply passage 12 by the expansion. Hence, the auxiliary hydraulic piston 10 operates up to the position of a stopper 10A, and the main hydraulic piston 7 is also pushed out. Therefore, when a hydraulic changeover valve is operated, the operating oil supply passage 11 communicates with the hydraulic pump side, and main and auxiliary hydraulic pistons 7 and 10 operate together. Hence, the interval between the main piston 7 and the friction plate 6 becomes small. At the time when the operating oil has a low temperature, only the main piston operates and the interval between the main piston 7 and the friction plate 6 becomes great. Drag at the time when the operating oil has a low temperature, can be prevented and the clutch fitting time at the time when the operating oil has a low temperature, can be minimized.

Title: Linearizer
Inventor: FUKUHARA YASUSHI
IPC: G06G7/20
Filed: 1980-11-18
Abstract: PURPOSE:To linearize a signal with a high precision by a simple circit, by inputting an input signal having a saturation characteristic to a voltage dividing circuit consisting of a resistance and an FET and by applying a voltage corresponding to the input signal to the gate of the FET. CONSTITUTION:A negative signal ei given to an input terminal 10 is applied to a source S of an N-channel depletion type FET through a resistance R1, and a drain D of the FET is grounded, and the signal ei is applied to a gate G of the FET also. When the resistance between the source and the gate of the FET is denoted as RSD, the output signal eo becomes the product between the input signal ei and a voltage division rate K=1/(1+R1/RSD). Since RSD is increased quadratic-functionally for the negative voltage applied acorss the gate G and the source S, the voltage division rate K is smaller than 1 for the small input ei and approaches 1 in accordance with enlargement of the input ei, and thus, the voltage division rate K is changed in respect to the saturation characteristic. Consequently, the resistance R1 is selected to change the output signal linearly for the input of the saturation characteristic.
