Title: Fast accessing device for optical disk driving device
Inventor: AOKI IKUO
IPC: G11B7/085
Filed: 1987-02-27
Abstract: PURPOSE:To heighten the position resolution of a carriage and to attain fast access, by using the position detecting sensor of the carriage having a sawtooth slit. CONSTITUTION:The output of the position detecting sensor 11 is converted to a sawtooth shaped voltage waveform by an I-V converter 14. The output of the converter 14 after being converted to a digital signal by an A/D converter 15, is supplied to a CPU 18. In such a way, it is possible to heighten the position resolution of the carriage. In such a state, since a fixed error is given to the sawtooth slit of the sensor 11, the error is corrected by a correction value stored in a linearity error detector 17. Also, the decentering of a track measured by a track decentering measuring instrument 19 is corrected by a track decentering corrector 21. Thus, it is possible to heighten the position resolution of the carriage and to attain the fast access.

Title: Fine current source circuit
Inventor: NAGANO KATSUMI
IPC: H02M3/00
Filed: 1981-03-27
Abstract: PURPOSE: To obtain a current of ≤μA precisely by a bipolar IC by lowering the base-emitter voltage of an output transistor (TR) as much as a voltage drop across a resistance by an input current, and thus reducing its output current.  
     CONSTITUTION: When the emitter areas of TRs Q 1 ∼Q 4  are represented as m 1 ∼ m 4 , m 1 >m 3 , m 4 , m 2 >m 3 , m 4 . Then, while an input current I is applied from a current source I to the collector of the TRQ 1 , a current nI which is (n)-fold as large as it is applied to the collector of the TRQ 3  as well. In this case, a current applying circuit 11 operates so that the collector current of the TRQ 3  is equal to the nI. As a result, the base-emitter voltage of the output TRQ 4  drops by as much as a voltage drop across a resistance R 1  by the circuit 11, reducing an output current I 0  from the TRQ 4 . Thus, a fine current of ≤μm is obtained precisely by a bipolar IC.

Title: Bushing attaching structure
Inventor: TAKAGI SEIZO
IPC: H01B17/26
Filed: 1988-02-26
Abstract: PURPOSE:To make a bushing unbreakable even a severe earthquake occurs by attaching the bushing to the equipment for electric power etc., via an anti- seism structure member. CONSTITUTION:Bushings 1 and 1' are attached to the equipment for electric power etc., via anti-seism structure members 8 and 8'. When the earthquake having strong wave motion energy occurs, the component of the earthquake is applied to the whole tank-type gas circuit breaker. Even if the component same as the characteristic frequency of the bushings 1 and 1' within a seismic wave component, the wave motion energy of the earthquake is absorbed by the deformation of the members 8 and 8'. Consequently the wave motion energy applied to the bushings 1 and 1' is largely attenuated, and excessive stress is unapplied to the attached parts 1b and 1b' of the bushings 1 and 1'.

Title: Automatic time recorder
Inventor: TANIMOTO AKIYOSHI
IPC: G11B27/10
Filed: 1978-04-17
Abstract: PURPOSE: To record the desired time without the use of a microphone thereby to improve the recording operability by applying the time signals, which are converted into audio signals, into a recorder through a gate which is so controlled as to be opened and closed at the beginning and end of the recording operation.  
     CONSTITUTION: If recording start and stop keys RK and SK are operated, a gate G is opened in response to the control signals Sg from an audio output circuit VC. Thus, the counted value of a time measuring register for counting the clocks of the oscillator of the circuit VC is converted into reading address signals so that the time signals St converted into the audio signals are fed to a recorder TR. The recording start and end times are automatically recorded without the use of a microphone by an operator. As a result, the operability upon the recording operation is improved so that the error in the operation can be reduced.

Title: Method for charging battery
Inventor: OOMORI MASARU
IPC: H02J7/02
Filed: 1979-04-14
Abstract: PURPOSE:To make it possible for a single charger to charge a multiplicity of battery groups, by charging battery groups individually until the charge end voltage is reached and then charging all the battery groups simultaneously for a preset time. CONSTITUTION:Two sets of battery groups are connected to the output terminals 7-1 and 7-2 of the charger. The starter switch 4 is closed to make the main electromagnetic switch 2 and the electromagnetic switch 8 communicated. Thus, only the battery group connected to the terminal 7-1 is charged. As the battery group connected to the terminal 7-1 has reached the charge voltage V1, the voltage relay 6 acts to start charging the battery group connected to the terminal 7-2. As the charge voltage reaches V1, the voltage relay 6 acts, causing the timer circuit 3 to start. Now, the terminals 7-1 and 7-2 are connected to both battery groups simultaneously, and the battery groups are charged for a preset time T (up to charging time t2) of the timer circuit 3.

Title: Image compositing device
Inventor: MOTAI MASAHIKO
IPC: H04N5/272
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To composite a supply image with a mixed image of main and sub images by outputting a supply image from a 1st supplying means at the detecting of a specified value in the sub image and outputting the mixed image from a generating means, when it is not detected. SOLUTION: When image data PXD of a sub video are prepared at the compositing of external videos, a part corresponding to a PDX 1 (2nd emphasis value) of the data PXD is switched from a main video to an output of the external videos, and the external videos are composited with the main and sub videos. That is, a PXD 1 circle is produced by using one 2nd emphasis value of four states of the data PXD, a character string is produced with a pixel value (either of them has a background value), the 2nd emphasis value is detected and an external video signal is switched and inserted. For a character string part having no 2nd emphasis value, the external video signal cannot be switched. For instance, if a pixel data PXD 2 circle part is a 1st emphasis value, it is not detected, and a triangular part of the main video becomes 6 star parts of the external video signal.

Abstract: PURPOSE: To surely perform starting and stopping of a siphon pipe with simple operation, by connecting a siphon pipe for backwashing to a water tank, and sucking air in  the siphon pipe by the water head difference obtained by discharging water in the tank.  
     CONSTITUTION: Raw water is fed into a water tank 19 to the water level A from a  raw water flow-in channel 2 by opening automatic valves V 3  and V 4  and closing automatic valves V 1  and V 5 . Next, when the valves V 3  and V 4  are closed and the valves V 1  and V 5  are opened, the water in the tank 19 is discharged from a discharging pipe  23 rapidly. As the water level in the tank 19 is lowered, air contained in a siphon pipe  5 for backwashing is sucked into the tank 19 through a communicating pipe 20, and  that causes a rapid drop of the air pressure in the siphon pipe 5 which is water sealed  by a chamber 13, into which waste water after backwashing flows, and a said water  staying chamber 16, accordingly water in a filtering basin 3 flows from the chamber 13  to a waste water staying channel 16 through the siphon pipe 5 and is discharged from a waste water discharging channel 18, thus the water level in the tank 19 is kept constant at the level D. Further, the stop of the siphon 5 is performed by the valves V 1   and V 4 .
