Title: Reproduction end detecting method
Inventor: MANIWA YOSHIO
IPC: G11B3/095
Filed: 1978-03-31
Abstract: PURPOSE:To perform the detection of reproduction end surely by beforehand recording the signal of the specified frequency for detecting the reproduction end between the final groove and lead-out groove of a record disc. CONSTITUTION:When a pickup 2 detects the constant frequency signal having been recorded between the final groove 9 and lead-out groove 8 of a record disc 1, a monostable multi 15 and retriggerable monostable multi 14 are triggered by way of a saturation amplifier 11, integrator 12 and Schmitt trigger circuit 13. Then, the outputs of the multi 14 and of the multi 15 through inverter 16 are applied to an AND gate 17 and the reproduction end signal which conducts a transistor 18 when the multi 14 goes ON and the multi 15 goes OFF is generated from the gate 17. Hence, the reproduction end is surely detected according to the setting of the time constants of the multis 14, 15 without using any switch or the like and the separation of the pickup from the record and the like are well accomplished.

Abstract: PURPOSE:To facilitate positioning by removing one parts of each layer formed in a region superposing on a dark film section as an alignment mark for a mask through etching in succession from an upper section in an extent that the phase of the period of reflectivity by the interference of monochromatic light is displaced and shaping light and darkness. CONSTITUTION:An Si substrate is insulated and isolated 107, 108, poly Si masks 113, 115 are applied onto SiO2 thin-films 109, 111, and an opening is bored to the film 109. The masks 113, 115 are coated with SiO2 117, 119, an opening is bored to the film 117 through etching and one part 121 of the film 119 is removed, and poly Si 113 is etched excessively. Wafer alignment marks 125 with alignment marks 121, 123 are completed at the time. Since the mark 125 has the difference of film thickness in sections 201, 203, reflected light is brought to light at every odd times of lambda/2 and to darkness at every even times by the interference of monochromatic light having a wavelength lambda. When using lambda=4,358Angstrom , the selection of approximately 900Angstrom  of the difference of film thickness is advantageous. The section 201 is brought to light and a section 202 to darkness in the alignment mark 121, and the masks can be aligned easily through scanning on the mark 121.

Filed: 1985-02-27
Abstract: PURPOSE:To always set the neutral point potential of a load to 0 by adding power control outputs of 3-phases obtained as current control outputs of phases, and feeding back them. CONSTITUTION:A DC power source 1 is supplied as 3-phase AC powers of variable frequency and variable voltage through an inverter 2 for PWM (pulse width modulation) controlling to an AC motor 3.

Abstract: PURPOSE:To reduce the number of program steps and shorten a processing time by a method wherein an actual wheel velocity is compared with an imaginary vehicle velocity to thereby discriminate whether or not the vehicle is being decelerated at a deceleration value of not less than amount 1G. CONSTITUTION:The antiskid device is provided with a wheel velocity sensor 1 which detects the wheel velocity and generates a number of pulses, the number being proportional to the wheel velocity, and the output signals from the sensor 1 are fed to a controlling circuit 2. The circuit 2 calculates an optimum slip factor and the slip of wheels on the basis of the signals from the sensoe 1, and generates a brake- moderating signal, which is used to control a brake oil-pressure circuit 4 through an actuator 3. In this case, the imaginary vehicle velocity is obtained by subtracting the product of the lapse of time (from the time when the deceleration was started at the deceleration value of not less than about 1G) and the deceleration value from the wheel velocity detected at the time of starting the deceleration. The imaginary vehicle velocity is compared with the actual wheel velocity to thereby discriminate whether or not the vehicle is being decelerated at a deceleration value of not less than about 1G.
