Title: Tracking controller
Inventor: SUZUKI MOTOYUKI
IPC: G11B7/09
Filed: 1990-01-24
Abstract: PURPOSE:To securely lead a light beam to a target track by varying the waveform of a tracking error signal to a specific level corresponding to the quantity of deviation of the light beam from the target track. CONSTITUTION:A waveform converting circuit 15 converts the waveform of the input tracking error signal (c) according to the outputs of a comparator 12 and a waveform shaping circuit 14 and inputs its output (d) to a switch 17. In tracking lead-in operation, the switch 17 is turned on with a tracking-ON signal (q) when the light beam enters a range of + or -P/4 about the target track, and the output of a phase compensating circuit 16 is inputted to a driving circuit 19 to perform tracking control. In track jumping operation for moving the light beam to an adjacent track, on the other hand, the switch 17 is turned off with a jump command signal (r). The signal (r) is inputted to a jump pulse generating circuit 22 to generate a jump pulse signal, which is inputted to the circuit to move the light beam to the adjacent track. Consequently, the light beam can securely be led to the target track.

Title: Ultrasonic meter
Inventor: HAYASHI EIJI
IPC: G12B11/04
Filed: 1993-01-29
Abstract: PURPOSE:To downsize a meter by converting positional information detected at a rotational angle detecting section into a signal having frequency low enough to be processed by an operational amplifier. CONSTITUTION:A rotary disc 22 constituting a rotational angle detecting section 20 rotates as an ultrasonic motor 10 rotates. A current collecting electrode 22 takes out a rotating electric field which is the sum of electric fields generated by electrodes 21a-21c. The rotating electric field having a frequency fc is applied to the gate electrode of a FET 55 having a drain electrode applied with a signal having frequency fL from a frequency divider 54. A band-pass amplifier 57 amplifies a converted signal having a low frequency representative of phase difference information and outputs the amplified signal. A phase detector 58 detects the phase of an output from the amplifier 57 with reference to a reference value and outputs a pulse. An integrator 60 compares the pulse with an input pulse 40 and performs switching control of the phase of driving signal. When a motor 10 rotates forward and reversely and the output from the integrator 60 goes zero, rotation of the motor 10 is stopped and the rotary position is read out from a pointer 30. The pointed value represents the magnitude of an input 40 to be measured.

Filed: 1989-01-25
Abstract: PURPOSE:To make the driving of a device possible by providing a freely reciprocating weighter, a weighter driving device, and a device driven by the weighter, and connecting them to the hydraulic cylinder of a high-pressure pneumatic turbine or the like to perform energy conversion. CONSTITUTION:When a driving motor M makes a crank rod 3 function to vertically move a weighter 1, which is suddenly pressed downward, and an oscillator 7 in the weighter intends to continue a downward movement, but an impact frame 6 rapidly stops the downward movement of the oscillator 7 to make the weighter 1 cause centrifugal inertia. A valve for the suction pipe 15 of a cylinder 12 directly connected with the oscillator 7 rises against a suspension spring 8 and a coil spring 10 for the oscillator 7 to suck air as it opens to its full opening. The centrifugal inertia caused by the immediately after downward movement of the oscillator 7 compresses the air in the cylinder 12, and the pressure of the above compressed air pushes the valve open. Thus the air is sent out through an exhaust pipe 16.

Filed: 1990-01-23
Abstract: PURPOSE:To markedly improve the preservability of the boiled product by adding water to grains and, when the grains are to be boiled, by adding an isothiocyanic ester to the system. CONSTITUTION:Water is added to grains such as rice, wheat, barley, soybeans or red beans, and when the grains are to be boiled, 0.005-0.5 (pref. 0.02-0.2)wt.% of an isothiocyanic ester is added to the system followed by boiling. Said ester is one of a variety of aliphatic and aromatic esters of isothiocyanic acid [pref. allyl isothiocyanate (CH2=CHCH2NCS) or an alkyl isothiocyanate (RNCS; R is alkyl group)]. Alternatively, for said ester, mustard oil can be directly used. With the present method, because of killing thermophilic bacteria attached to grains never drying even by heating at 100 deg.C, the preservability of the grains can be markedly improved.
