摘要： PURPOSE:To steplessly adjust the position of a head rest main body by tightening and pressurizing a joint member inserted to the head rest main body and a fitting block, and generating friction force among a stay, the head rest main body and the attaching block. CONSTITUTION:The top part of a stay 3 fixed at a seat back is inserted into the engaging groove of a fitting block 2, the block 2 is fit into a recessed part 8 to the heat rest main body 1, a joint member 10 is tightened, and the head rest main body 1 and the fitting block 2 are pressured in mutually approximating directions. Force is applied in the direction, in which the stay 3 is deformed, by the head rest main body 1 part and the fitting block part 2, which abut on the stay 3, and the force generates the friction force between the stay 3 and the head rest main body 1 and between the stay 3 and the fitting block 2. Thus, the position of the head rest main body 1 can be steplessly adjusted, and play can be prevented.

摘要： PURPOSE: To set a constant and accurate catch detection range at all times by measuring motor power voltage, upon arrival at a complete closing position, and making a correction for learning on the basis of a correlation between the value of the voltage and a dead zone. CONSTITUTION: A power window regulator circuit 30, upon judging that the upper end of window shield glass reaches a completely close position and a window shield glass elevator motor 26 is locked, measures the power voltage of a motor 26. A correction is, then, made for learning, on the basis of a correlation between a preliminarily stored power voltage value, and a dead zone from a reference position to a catch detection range, and a position for entering a dead zone corresponding to the measured voltage is thereby established. As a result, a constant and accurate catch detection range can always be determined.

摘要： PURPOSE:To provide a switching regulator which can reduce a power loss with good controllability and whose circuit constitution is simple. CONSTITUTION:An error amplifier 41 operates an error between an output voltage Vout and a reference voltage Vr, and it sets a duty ratio duty for a transistor 44. The output VEA (which is proportional to the duty) of the error amplifier 41 is compared, by a PWM comparator 42, with triangular waves which are output from a triangular-wave oscillator 11, and it is converted into a PWM waveform. A base driver 43 is controlled so as to be turned on and off according to the PWM waveform. At this time, a multiplier 12 performs an operation so as to multiply the duty ratio duty by an input voltage Vin, and it generates an optimum base current IB. A collector current IC (a primary current i1 at a transformer 47) is changed according to the base current IB, and a secondary current i2 at the transformer 47 is changed according to its change. Then, the secondary current i2 is rectified with a rectifier circuit 48, and an output voltage VOUT is output.

摘要： PROBLEM TO BE SOLVED: To ensure high electromagnetic conversion efficiency between a coil placed to a key and an antenna coil placed to a car side for a favorable car lock device used as the device preventing car burglary. SOLUTION: A circular section 10a is provided to a key 10. A coil is placed inside the circular section 10a. A cylindrical antenna coil 20 passing through the circular section 10a or the coil is placed to the central part of a key cylinder 12 when the key 10 is loaded. Amplifier 14, ECU (electronic control unit) 16 EFI (engine control) computer 18 are connected to the antenna coil 20. ECU 16 outputs a signal permitting the start of car to the EFI computer 18 only when a proper ID signal is communicated between the coil and antenna coil 20.
