Title: Quartz lock compact tape recorder
Inventor: TAKAYAMA TOMOTOSHI
IPC: H02P29/00
Filed: 1979-04-04
Abstract: PURPOSE:To provide a motor control circuit of low cost and high stability, by using a crystal oscillator, a frequency dividing circuit, a digital phase comparator, a low- pass filter, etc. for the motor control circuit. CONSTITUTION:A crystal osicllator is composed of a frequency dividing circuit 302 and an oscillation circuit employing a crystal resonator 301 to produce reference frequency. The rotational frequency of a motor 311 is detected by detection elements 303, 304 to apply a signal to a point V of a phase comparator 312. When the phase of the signal is delayed with regard to that of a reference signal applied to another point R of the phase comparator, a negative logic pulse is sent out from another point U and electric charge is released from the capacitor 307 of a low-pass filter comprising the capacitor and resistors 305, 306 and the base potential of a transistor 308 falls. As a result, control is effected by the emitter potential of a transistor 310 to correct the delay of the terminal voltage of the motor. When the phase of the signal to the point V precedes that of the reference signal, an output signal appears on a point D and similar control is effected.

Title: Ink supplying device and recording device
Inventor: FUJII KATSUYUKI
IPC: B41J2/175
Filed: 1995-02-28
Abstract: PURPOSE: To provide an ink supplying device, precluding the invasion of bubbles into a print head without increasing the resistance of a flow passage and capable of detecting the remaining amount of ink. CONSTITUTION: An intermediate ink chamber 4 is provided on the side surface of a main ink chamber 2, accommodating a capillary member 3 and provided with a communicating hole 7, while both of them are communicated through a communicating passage 5 as well as a joint port 11.

Title: Correction of defect in photomask
Inventor: ONODA HIROSHI
IPC: G03F1/00
Filed: 1988-02-24
Abstract: PURPOSE:To restore the optical transmittance of a corrected part of a black defect and to permit highly precise and fine correction of a photomask by removing excessive light shielding material by irradiating a black defect with a convergent metallic ion beam, then oxidizing metallic ions injected into a substrate by irradiating with ultraviolet rays in ozone atmosphere. CONSTITUTION:An excessive light shielding material is removed by irradiating a black defect of a photomask with convergent metallic ion beam, then irradiating with ultraviolet rays in ozone atmosphere. Since the metallic ions are irradiated with ultraviolet rays in ozone atmosphere after the light shielding material has been removed, the metallic ions are oxidized and color centers are eliminated. Thus, optical transmittance deteriorated by the color centers is restored. By this method, highly precise and fine correction of a photomask become possible.

IPC: G01N35/10
Filed: 1987-02-26
Abstract: PURPOSE:To quickly check the abnormality in measurement data and the cause thereof by mounting a sensor for detecting the air bubbles contained in liquid near a discharge port of a flow passage in which the liquid requiring fixed rate dispensing flows. CONSTITUTION:A sample tube 1 forms the flow passage for a reagent communicating with a reagent bottle which is not shown in the figure. A dispensing nozzle 2 is connected to the end of a reagent tube 1 and forms the flow passage for the reagent and a discharge port 2a. The reagent is discharged by pump driving through the reagent tube 1 and the dispensing nozzle 2 from a reagent bottle which is not shown in the figure. The reagent fed in the tube 1 is checked for the presence or absence of the air bubbles included therein by a photointerruptor 3 just before discharging. The output of the photointerruptor 3 is disturbed as well according to the disturbance A in the quantity of light if the air bubbles are included in the reagent. An error code is, therefore, outputted to inform the operator of the abnormality.

Inventor: OZAWA YOSHIHIRO
IPC: G09G3/36
Filed: 1991-01-24
Abstract: PURPOSE:To obtain the liquid crystal video projector which prevents the visibility from deteriorating even when the screen is made large and its driving method. CONSTITUTION:Light which is modulated by panels 5, 6, and 7 of R, B, and G is modulated by being passed again through the panels 20, 21, and 22 of R, G, and B or through a panel which is modulated with a Y signal, so the transmission characteristics of liquid crystal approximate to those of TV. Further, two optical modulation systems are shifted upward and downward for projection and the gate selection period of a panel of each system is set to a two-line period, so the aperture rate is improved. Further, one and other two colors of the panels of R, B, and G or the polarities of video signals at the time of AC driving of two optical systems are made different, so mutual brightness characteristics cancel each other to reduce a flicker.

Title: Control system for cold condition idle up and exhaust gas recirculation in internal-combustion engine
Inventor: SASAOKA HIROSHI
IPC: F02M25/07
Filed: 1981-03-24
Abstract: PURPOSE:To operate the system in high accuracy by a method wherein respective vacuum operating chambers of the system effecting the idle up in the cold condition of the internal-combustion engine and stop of the exhaust gas recirculation at the same set temperature are connected to a common temperature sensitive valve responding to the temperature of the engine. CONSTITUTION:While the engine is cold, the ports 70a, 70b of an atmosphere opening and closing valve 60 are opened. The atmophere through the port 70a is entered into a diaphragm chamber 30 for a dash pot 20 by a jet 36 while a spring 28 pivots a throttle valve 12 slightly to increase the idle revolution and thereby effecting the idle up. The atmosphere from the port 70b is flowed into the diaphragm chamber 50 of a EGR valve through pipelines 82', 52, therefore, a valve body 42 is closed and the exhaust gas recirculation (EGR) is not effected. After the warming-up of the engine, a bimetal 64 closes the ports 70a, 70b and stops the introduction of the atmosphere, therefore, the vacuum in a port 34 is entered into the chamber 30 and the idle up is released. When the vacuum of a vacuum port 54 is higher than the set vacuum of the EGR valve 40, the valve body 42 is opened and the EGR is effected.
