Title: Foreign matter inspection device
Inventor: DANSUI YOSHITAKA
IPC: G01N21/94
Filed: 1989-10-09
Abstract: PURPOSE:To detect the foreign matter on a solid substrate and to the foreign matter to be measured regardless of the condition of solid substrate surface by providing plural pieces of piezoelectric oscillators on a plane so as to put it into matrix structure, and providing the piezo electric oscillators so that they may be opposed at regular intervals. CONSTITUTION:A high frequency pulse generator 1 generates high frequency, which is supplied through circulators 4 and 5 to an upper piezoelectric oscillator group and a lower piezoelectric oscillator group 3. By giving high frequency to the piezoelectric oscillator groups 2 and 3, ultrasonic waves 7 are generated. If a substance to be measured, for example, a semiconductor substrate 9 put between the upper piezoelectric oscillator group 2 and the lower piezoelectric oscillator group 3, ultrasonic waves 7 generated by piezoelectric oscillators are reflected by the semiconductor substrate 9, and return to the piezoelectric oscillators as reflected waves 8. By moving the semiconductor substrate 9 back and forth and right and left on the same plane, the foreign matter adhering to all the faces of the semiconductor substrate 9 can be detected.

Title: Track position controller for information recording medium of recording device
Inventor: HIRASAWA KAZUO
IPC: G11B21/08
Filed: 1986-11-05
Abstract: PURPOSE:To perform track jumping operation at a track control position speedily and stably by obtaining track pitch information and varying and controlling the width of a brake pulse. CONSTITUTION:A track pitch detecting circuit 18 transmits current track pitch information to a brake pulse width control circuit 19 with track pitch information command from a sequencer or track pitch information computed and detected from a voltage applied to a slide feed motor in normal reproduction. A brake pulse width control circuit 19 sets desired pulse width according to track pitch and sends a command to a kick pulse generating circuit 13. Consequently, the brake pulse width corresponds to the track pitch and, for example, brake pulse width TBW is obtained, so that the end point C of the brake pulse is nearby the center of a 2nd track 16 in a light convergent spot moving direction. Therefore, even when the track pitch P is different, the stable track jump operation is performed in a short time.

Title: Development of system for identifying/determining compound through gasification of composite chemical material
Inventor: SAITO MICHIYA
IPC: G01N25/02
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain a system for identifying/determining a mixture of organic and inorganic material, a mixture of organic material, a mixture of inorganic material, a single organic material and a single inorganic material. SOLUTION: In order to measure a material having gasification temperature other than 250-350 deg.C, a temperature gradient of -270 deg.C-10000 deg.C is applied to a heating container 5 thus gasifying a composite chemical material. When the chemical substance is gasified, an energy level difference sensor 7 inserted into the heating container 5 transmits an energy level difference (mass) to a detector 10. Since the pointer of the detector 10 swings in proportion to the mass, chemical material in the composite chemical material can be identified/ determined.

Title: Comparator circuit
Inventor: YAMANOI YASUTOMO
IPC: G01R19/165
Filed: 1987-10-21
Abstract: PURPOSE:To obtain a stable output by performing conversion from a voltage base to a time base and providing hysteresis. CONSTITUTION:At the output stage of a comparator part A which has an analog voltage input terminal 1 and a comparison voltage input terminal 2, (n) stages of shift registers B(B1-Bn) are provided, a clock phi1 is inputted to the odd- numbered stages of the registers B, and a clock phi2 is inputted to the even- numbered stages so that the clocks phi1 and phi2 have phases without any high-level overlapping. Uninverted outputs 8-10 of the registers B and ANDed 15 respectively to generate a set signal for a trailing R/S.FFD and the inverted outputs 11-14 of the registers B, on the other hand, are ANDed 16 respectively to generate a reset signal. When the period of the clock phi1 and phi2 is denoted as T1 and their phase difference is denoted as T2 here, a delay of time T=(n/2-1)T1+T2 is caused from the rising of the output of the comparator part A to a high level to the output of the set signal when the number (n) of the registers B is, for example, even. The voltage base is therefore, converted into the time base to provide the hysteresis for the time T.

Title: Solenoid valve
Inventor: INABA KATSUMI
IPC: F16K31/06
Filed: 1994-10-27
Abstract: PURPOSE: To provide a solenoid valve easy to assemble without requiring machining accuracy by providing a passage transforming chamber in a case with an intake port formed at one wall of mutually opposed chamber walls and with a discharge port formed at the other wall, disposing a valve body formed of an elastic member therein, and driving the valve body to open/close by an electromagnet. CONSTITUTION: When a current flows to an electromagnet 23, a plunger 25 is sucked to move downward, and a valve body 26 opens an intake port 14 and closes a discharge port 20. A pressurized fluid therefore flows into a passage transforming chamber 12 from the intake port 14 and fed to a supplied part from a supply port 15. When the fluid flows into the passage transforming chamber 12, the valve body 26 is pressed to the side of closing the discharge port 20 by fluid pressure, and when the current to the electromagnet 23 is cut off afterwards, the suction of the plunger 25 is released, so that the valve body 26 is moved onto the intake port 14 side by a spring 27 to open the discharge port 20 and to close the intake port 14. As a result, the fluid is discharged from the supply port 15 through the passage transforming chamber 12, the discharge port 20 and an opening 22.

Title: Controlling system for starting and stopping vibrator type actuator
Inventor: TODA KOJI
IPC: H02N2/00
Filed: 1990-10-01
Abstract: PURPOSE:To realize the title system which does not generate any frequency drift and is excellent in responsiveness by applying AC voltages across a piezoelectric vibrator composed of the first electrode, second electrode, and the third electrode provided on the surface of a ceramic piezoelectric body perpendicular to the axis of polarization and the first and third electrodes. CONSTITUTION:Since an oscillator 11 always operates, the occurrence of frequency drifts caused by the temperature change of the oscillator 11 and a piezoelectric vibrator 20 due to internal heat generation is reduced and the stable operations of a vibrator type actuator are secured. When a switch 12 is opened or closed, the rising time of the vibrator type actuator does not exist at the time of actuating the actuator and the actuation and stoppage of the actuator which are excellent in responsiveness are realized, since the characteristic of the vibrator 20 instantaneously changes and the resonance frequency varies. Moreover, when the short circuit between electrodes 23 and 24 and the opening time of the electrodes 23 and 24 are arbitrarily set, the vibrator type actuator can perform stepping operations.
