Title: Semiconductor integrated circuit
Inventor: MURAYAMA TETSUYA
IPC: H01L27/04
Filed: 1989-06-02
Abstract: PURPOSE:To suppress the change of the resistance of a semiconductor diffused resistor and avoid the distortion of an output signal by a method wherein the potential of the island of the semiconductor diffused resistor is made to be a self-potential through a semiconductor resistor different from the semiconductor diffused resistor. CONSTITUTION:While a mu-transistor 7 is in an OFF-stage, if an input signal from a signal input part 2 is denoted by Vi, the resistance of a semiconductor diffused resistor 3 is denoted by R3 and the resistance of an output load resistor 8 is denoted by R8, an output signal Vo obtained from an output terminal 4 is expressed by the formula: Vo={R8/(R3+R8)}Vi...(A). As the potential of the island of the semiconductor diffused resistor 3 is made to be a self- potential through a semiconductor resistor 9, the difference between the potential of the island (N-type diffused region) and the diffused resistor (P-type diffused region) can be small and the change of the resistance R3 of the semiconductor diffused resistor 3 caused by the input signal Vi can be suppressed, so that the input signal (Vi)-dependability of the resistance R3 of the semiconductor diffused resistor 3 in the formula (A) can be reduced and the distortion of the output signal Vo can be suppressed.

Filed: 1982-08-16
Abstract: PURPOSE:To detect a tape travel speed in case of a control system which records pilot signal of cyclically varying frequency on every track by generating a travel detection signal on the basis of waviness occurring to a reproduction tracking error signal. CONSTITUTION:The pilot signal detecting circuit 32 of a helical scan VTR, etc., detects the pilot signals of different frequencies recorded cyclically on respective tracks for tracking control, and the error signal generating circuit 3 generates a tracking error signal S3 for the frequency difference between the reproduction pilot signals.

Title: Heating system for vehicle and scroll type pump which can be used to heating system
Inventor: KADOKAWA MASARU
IPC: F04D5/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To dispense with a throttle part at the discharge side of a pump, by obtaining a sufficient heating amount, as well as allowing to use a cooling water for engine with a low viscosity as a friction fluid, in a pump to generate a friction heat by a fluid by adding a motive power for the auxiliary heating of an automobile. SOLUTION: In this scroll type pump 30, the fluid inlet 8 is connected by making one end of a circular fluid passage 4 formed to a housing 2 in a low pressure part 11, but a high pressure part at the other end is being to be blocked, and the fluid outlet 9 is connected at a middle pressure part 12 on the way of the fluid passage 4. A high pressure of cooling water at the high pressure part 13 is leaked to the low pressure part from a partition part 10, and the heat by the fluid friction is stored in the cooling water, and as a result, a sufficient heating amount can be obtained even though a throttle part is not provided. Regardless of the above fact, by selecting the position of the middle pressure part 12, a random height of discharge pressure and discharge amount can be obtained.  Since no throttle part is provided, a fear to block the throttle part by a foreign matter is eliminated.
