Title: Digital audio disk player
Inventor: KOYAMA KENICHI
IPC: G11B20/00
Filed: 1984-02-24
Abstract: PURPOSE:To vary steps of sound signals to be reproduced by using a common oscillation circuit containing a signal processing circuit, a spindle control circuit and a D/A converting circuit as a frequency variable oscillation circuit. CONSTITUTION:When the frequency of a frequency variable oscillation circuit 8 is increased, a reference clock 5B of a spindle control circuit 7 is also increased. As a result, a spindle motor 2 is accelerated to increase the number of revolutions of a disk 1. In this case, a digital signal 5D which is sent to a D/A converting circuit 6 from a signal processing circuit 5 is increased for its information quantity per unit time by a degree equivalent to the rise of the frequency of the clock 5B. At the same time, the frequency of a deglitcher signal 5C is also increased. Therefore an audio signal is compressed in the same ratio toward a time axis. When the frequency of the circuit 8 is reduced, a signal 6A is expanded in the same ratio toward the time axis. In other words, the time axis can be compressed and expanded in proportion to the changing degree of frequency. Thus the step of the audio signal can be varied.

Title: Crystal oscillating circuit for electronic watch
Inventor: SHIMADA KENJIROU
IPC: G04G3/04
Filed: 1979-03-23
Abstract: PURPOSE:To improve at the same time a minimum operating voltage in a low- temperature range and current consumption in a high-temperature range, by separately performing the temperature compensation of the frequency of a crystal oscillating circuit in the low-temperature range and high-temperature range. CONSTITUTION:Temperature compensating capacitors C1 and C2, and C1' and C2' differing in Curie point are connected in parallel respectively and then connected to input terminal IN and output terminal OUT of inverter 2 of a crystal oscillating circuit. In the low-temperature range, capacitors C1 and C2 only decrease in capacity to perform the temperature compensation of its oscillation frequency and also to suppress an increase in minimum operation voltage. In the high-temperature range, only capacitors C1' and C2' decrease in capacity to compensate a temperature at the oscillation frequency and also to suppress an increase in current consumption.

Title: Polishing device and method
Inventor: DOI TOSHIRO
IPC: B24B37/04
Filed: 1988-02-19
Abstract: PURPOSE:To polish a sample into a desired condition regardless of the initial surface condition and without interrupting the polishing work by monitoring the current level through a current detecting means during polishing work thereby grasping the condition of the face to be polished. CONSTITUTION:A tool lathe for polishing a work (sample) is coupled through a spindle with a drive source 21, and the drive therefor, i.e. a DC motor 21, is coupled with a rotation detecting means 22. A drive signal (b) is fed from a three-phase amplifier 53 to the DC motor 21 based on a signal detected through the detecting means 22 in order to control the rotary speed of the DC motor 21. Furthermore, terminal voltage V of a current resistor 54 connected in series with transistor group S1-S6 connected with the DC motor 21 is read through a voltmeter (current detecting means) 55 at a source detecting section while the current fed to the DC motor 21 is detected and monitored during polishing work of the work thus grasping the condition of the polishing face. Consequently, the polishing face of the work can be polished to a desired condition in short time without interrupting the polishing work.

Title: Starting and stopping method for waste-heat recovery boiler
Inventor: NISHIKAWA ISAO
IPC: F22B35/00
Filed: 1991-02-06
Abstract: PURPOSE:To detect the heat input state to automatically control pressure increasing and reducing operation in starting and stopping conforming to the pressure increasing and reducing curves by measuring the temperature and pressure of steam and the flow rate of feed water or steam. CONSTITUTION:When the inlet gas temperature of a boiler becomes the minimum temperature Tgmin or higher, a feed water apparatus is put in operation, a relief valve is opened, a steam stop valve is closed and the control set points of generated steam temperature and pressure are respectively set at TsO and PsO. When the temperature and pressure reach the set points and the flow rate of feed water becomes Wmin 1 or higher, the control set points of pressure and temperature of generated steam are changed with time elapsed conforming to the pressure increasing and pressure reducing curves. When they reach Psmin and tsnor respectively, the steam stop valve is opened, and when the control set point of pressure reaches Psmax, the relief valve is closed. If Psmin and Psmax are selected so that their relationship with the normal service pressure Pnor at an end user satisfies a formula Psmin<Pnor<Psmax, the generated steam is naturally changed from the open-to-atmosphere state to the supply state, and pressure increasing and reducing operation at starting and stopping can be automated.

Title: Bipolar signal receiving circuit
Inventor: MIZUSAWA TSUNETOSHI
IPC: H04L25/40
Filed: 1979-03-27
Abstract: PURPOSE:To obtain a bipolar signal receiving circuit with a small influence of jitter, by taking out the output of a timing signal extraction circuit only when the output of an equalizer is larger than the threshold level signal generated from the equalizer output signal. CONSTITUTION:Bipolar signal 11 is equalized by equalizer 1 and is rectified by full-wave rectifying circuit 2 and becomes signal 13. Automatic threshold control circuit 3 generates optimum threshold level 14 on the basis of signal 13, and slice circuit 4 slices signal 13 with this level 14 to make signal 13 into digital signal 15. Then, the output of equalizer 1 is applied to extreme value point detection circuit 7, and the output is differentiated by differentiating circuit 8 and becomes timing signal 19. Timing signal 19 passes through gate 19 to become timing signal 20 only when digital signal 15 is logical ''1''. Thus, timing signal 20 with a small influence of jitter can be obtained.

Title: Optical pickup device
Inventor: MAEDA IKUO
IPC: G02B7/28
Filed: 1989-02-15
Abstract: PURPOSE:To eliminate the misalignment of an optical axis caused when a turning mirror is rotated under the state of the position of a reflecting point being conformed with the rotational center position of the turning mirror by setting the rotational center position of the turning mirror in its moving position by a specified distance from the position of the reflecting point along the parallel direction to the optical axis and the vertical direction to the optical axis. CONSTITUTION:Outgoing light (a) from a semiconductor laser 6 is reflected by a beam splitter 9, and is moreover reflected in turn by a deflecting mirror 10 and the turning mirror 11 to be emitted out to the exterior. This emitted light is reflected by a deflecting mirror 13 and converged by an objective lens 14 to irradiate an optical disk 15, so as to record or reproduce information. In this case, when a focal distance of the objective lens 14 is denoted as (f), and a distance between this objective lens 14 and the reflecting point P of the turning mirror 11 is denoted as (l), the rotational center position of the turning mirror 11 is set in its moved position by approximate 2<1/2>(l - f) from the position of the reflecting point P along the parallel direction to the optical axis and the vertical direction to the optical axis. By this method, the misalignment of the optical axis can be eliminated.
