Title: External clock generator and data reproducing apparatus
Inventor: CHIAKI SUSUMU
IPC: G11B20/10
Filed: 1993-08-27
Abstract: PURPOSE:To accurately reproduce data by selecting external clock having the optical phase for sampling of the reproduced signal using the reference signal recorded on a recording medium. CONSTITUTION:An A/D converter 18 executes the sampling using a clock transmitted from a selector 16. During the sampling of the reference information recorded on the recording medium, the selector 16 sequentially selects external clocks CK0 to 3 having different phases for each sampling to send these clocks to the A/D converter 18. An arithmetic circuit 20, FF21 and EXOR22 send a polarity change data of the differential value regarding the current and preceding sampling data to the controller 30. When polarity of differential value is changed, the controller 30 sends a command to the selector 16 to sample the subsequent recorded data with an external clock having currently phase outputted.

Title: Method and circuit for current limitation of voltage-type inverter
Inventor: SASAKI TOSHIYUKI
IPC: H02M7/48
Filed: 1994-08-16
Abstract: PURPOSE: To always limit a current irrespective of a region to which a back- electromotive-force vector belongs by a method wherein, when an output current exceeds a limit value, switching elements at all phases are cut off for a definite period, the counter electromotive-force vector of a motor is detected and an output voltage vector in a direction in which the output current is reduced is selected and controlled. CONSTITUTION: For example, when a u-phase current exceeds a limit value, a signal is input to a base-signal selection circuit 5 via an OR circuit 4, a base cutoff signals at all phases with reference to an inverter are output for a definite period, and all transistors are turned off. At this time, on the basis of output voltages eu , ev , ew at respective phases of the inverter and on the basis of the angle of rotation θ of an output voltage, a region discrimination device 7 can discriminate to which region the counter-electromotive-force vector of a motor belongs. An output-voltage vector is selected, and a current-change-rate vector does not have the forward component of the u-phase current. As a result, the u-phase current is reduced, and a current can be limited.

Title: Pie-character processing system
Inventor: ADACHI SHIGERU
IPC: B41J5/30
Filed: 1986-09-12
Abstract: PURPOSE:To perform continuous printing by using one buffer (FMB) storing pie-character codes and pie-character patterns to make it possible to store the data of a plurality of pages and mounting a table storing the correspondence of each page and data in a page buffer. CONSTITUTION:When a writing or load command is inputted to a printer from a channel, the FMB pointer 26a1 in a table 26 shown by a writing point 26c sets the head position of FMB 25 and FMB data quantity 26b1 is set to zero at the time of the writing command and, at the time of the load command, the quantity of the data of the pie-character code and pie-character pattern inputted with the input of said command is set. When the data of one page are stored, the writing point 26c is renewed. By this method, the page data of several pages are accumulated in a page buffer 5, and the pie-character code and pie-character pattern are accumulated in FMB25. Therefore, even when the input from the channel is temporarily delayed, the delay is restored during the printing of the page data in the page buffer to make it possible to perform continuous printing.

Title: Dimming device for discharge lamp
Inventor: TOKUNAGA KENSUKE
IPC: H05B41/392
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To effectively dim the discharge lamp by executing variable control for the amplitude of a high frequency power supply in proportion to a command value by a chopper circuit part, and also executing variable control for the frequency of a high frequency power supply in proportion to a command value by an inverter circuit part. SOLUTION: A chopper circuit part 9 allows the output of a switching transistor Q1 for electric power to be smoothed out by a smoothing actor L2 and a smoothing capacitor C2 so as to allow variable control for the amplitude of a DC power supply to be executed. The aforesaid output is returned to an error operator 13, the difference between the output and the amplitude command value Vref of an amplitude command producing part is thereby obtained, and the difference is sent to a drive circuit 15. The circuit 15 allows the input electric power of an inverter circuit part 10 to be controlled to be the amplitude command value Vref.  Besides, the frequency command value Fref of a frequency side command value producing part 7 is fed to a drive pulse generator 20, and drive pulses each amplitude of which is changed in proportion to the command value, are generated in drive circuits 16 through 19. And the circuit 10 converts an input DC power supply to a high frequency power supply based on the command value Fref by pulse amplitude control so as to be sent to a feeder line 2 through a transformer 21 and output terminals 22a and 22b.

Title: Drink dispenser
Inventor: SAEKI TATSUO
IPC: A47J31/057
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To provide a drink dispenser which positively prevents an overflowing water from spilling to the outside of the dispenser and is less costly in terms of installation/operation and also can be handled easily. SOLUTION: Overflow piping 20 running from a hot water supply tank 5 is connected to a water storage tank 2. In the hot water supply tank 5, a water level is kept almost constant by detecting the water level using a float switch 18 and controlling the drive and the stoppage of a pump 6 based on the detection results. In the case that the float switch 18 malfunctions to allow the continued drive of the pump 6, the overflow of the hot water supply tank 5 occurs. In this case, however, the overflowing water is totally circulated back to the water storage tank 2, so that the spillage of the overflowing water to the outside of the dispenser is positively eliminated.  In addition, it is no longer necessary to provide a drain tank separately, so that an installation space is saved by this drain tank, contributing to the miniaturization of the dispenser and the reduction of a manufacturing cost. The incidental operation to drain the drain tank also need not be considered to lessen a financial burden on the part of a user.

Title: Ferrule for fixing constant polarization optical fiber and method for fixing constant polarization optical fiber by using said ferrule
Inventor: ISONO HIDEKI
IPC: G02B6/36
Filed: 1988-08-31
Abstract: PURPOSE:To fix a constant polarization optical fiber to a ferrule without degrading the extinction ratio thereof by providing an optical fiber insertion hole and an adhesive agent relief part having a prescribed shape to the ferrule. CONSTITUTION:The ferrule for fixing the constant polarization optical fiber is formed with the fiber insertion hole 1 and the adhesive agent relief part 2 having the shape of partially retreating the part where the plane inclusive of the center line of the hole 1 intersects with the wall surface of the hole 1. The optical fiber 3 is inserted into the hole 1 and the adhesive agent 4 is packed into the hole. After the main axis direction of the double refraction of the optical fiber 3 is adjusted in parallel with the relief hole 2, the adhesive agent 4 is cured by heating. Since the coefft. of thermal expansion after curing is larger with the adhesive agent 4, shrinkage force is generated when the fiber is cooled. The tensile force which is larger in the relief part 2 and is small in the rest of the part is then generated. This stress has no bearing to the thickness of the adhesive agent and the mode coupling arises hardly. The degradation in the extinction ratio is thus prevented.
