Title: Ultrasonic vibration driving type thermal transfer printer
Inventor: NANAI SADAAKI
IPC: B41J2/32
Filed: 1987-05-25
Abstract: PURPOSE:To prevent a medium part from moving in a slipping condition relative to a thermal head part, by exciting a progressive wave in a vibrator, thereby rotating the medium part and a platen. CONSTITUTION:An array of heat generating elements 2 provided on the outer surface of a virator 6, which comprises a vibrator 8 of a piezoelectric converting material provided, on the outer surface thereof with an elastic body 7, and an array of conductors 3 for energizing the elements 2 are in face-to-face contact with a medium part 4, which is a movable body, and a platen 5. When a progressive wave is excited in the vibrator 6, a surface part of the vibrator 6 is moved along an elliptic orbit. Since the elliptic orbit is rotated coutnerclockwise, the medium part 4 and the platen 5 are moved in the direction of an arrow by a propulsion in the direction opposite to the propagating direction of a composite wave. Therefore, no slipping occurs between a thermal head part and an ink film, and a high pressure can be exerted between them.

Title: Clogging detecting device for internal combustion engine air cleaner
Inventor: HORIE KAZUYUKI
IPC: F02M35/09
Filed: 1987-05-25
Abstract: PURPOSE:To prevent improper operation due to the pulsation of negative pressure before the marginal clogging of a filter element, and detect the changing and cleaning time of the element by providing a means for damping the pulsation of the negative pressure between an intake passage and the negative pressure chamber of a clogging detecting device. CONSTITUTION:When an internal combustion engine operates, intake negative pressure is transmitted to the valve chamber 21 of a clogging detecting device 1. When pulsation pressure in the valve chamber 21 is low, the spring 44 of a pulsation damping valve 4 presses a valve body 45 to the side wall of a casing 36. When the pulsation pressure increases, the valve body 45 is displaced simply right and left, and the pulsation pressure is dampened in a negative pressure chamber 31 nearly to a static pressure level. When the pressure reaches a value corresponding to the marginal clogging of a filtration element, a diaphragm 32 overcomes a spring 34 and shifts to a position near an intake pipe. Then, the contact point 35a of an operation switch 35 comes in contact with the contact point 35d of a connection fitting 35f at the side of a lamp, thereby turning a warning lamp ON.

Title: Inverter device
Inventor: SEKINO YOSHIHIRO
IPC: H02M7/48
Filed: 1988-05-25
Abstract: PURPOSE:To reduce size, weight and noise by inserting PWM semiconductor switches each having high speed switching characteristic in a DC power source and an inverter circuit. CONSTITUTION:An inverter device is composed of semiconductor switches Q1-Q4, etc., an AC voltage between points (a) and (b) is used as a sine wave voltage having a small distortion through the reactor L and the capacitor C of an AC filter, and applied to a load Load. In this case, an anti-parallel circuit of a PWM semiconductor switch Q5 and a diode D5 is added to the inverter device. The diode D5 feeds back the reactive power of the reactor L, the capacitor C of the AC filter and the load Load to a DC power source E. Thus, the switch Q5 is intermittently interrupted by a controller to apply a DC PWM voltage to the inverter circuit, and switches the switches Q1-Q4 of the inverter circuit during a period in which the switch Q5 is OFF. As a result, the switching can be conducted in a state that the voltage is zero.

Filed: 1992-05-20
Abstract: PURPOSE:To achieve reduction of probe diameter and enlargement of the probe scanning range simultaneously so as to enable measurement corresponding to miniaturization of LSI by providing independent tubes to correspond to two kinds of modes. CONSTITUTION:A tube 11 for the scanning electron microscope mode (SEM) has a deflecting system 15 and an objective lens 16 and the amount D of deflection of the tube 11 is larger than that (d) of deflection of a voltage measuring tube 21 so that a wide scanning range is provided. Secondary electrons that a sample W generates are converted by the tube 21 into pulses at a blanker 22 and measured as voltages. The use of the two sets of tubes corresponding to that mode simultaneously enables reduction of probe diameter and enlargement of the probe scanning range which are inconsistent with each other, thus providing an electron beam device which can deal with miniaturization of LSI.

Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To elongate gear life longer than the life of a resin gear and reduce gear sound by molding a gear body out of resin and vapor depositing a metal film on a tooth part to be engaged with another gear. SOLUTION: This spur gear 1 used for a geared motor, an electric tool, etc., has a gear body 2 having a plurality of teeth parts 2b formed in the outer circumference of a disc flat plate 2a molded of resin, and, a hard material, for example, a metal film 3 is vapor deposited on the side surface of the teeth parts 2b of the gear body 2. The spur gear 1 is provided with the hard material in a part where teeth parts 2b of the gear are brought in contact with each other so that the abrasion of the teeth parts 2b of the gear can be reduced and the life can be elongated.

Title: Method and device for controlling light spot
Inventor: TERAO MASATOSHI
IPC: G11B7/09
Filed: 1990-05-18
Abstract: PURPOSE:To efficiently perform the control of an image-forming position by making a beam of light on an objective lens by inclining by a wedge type prism, varying inclination by turning the prism, and turning the optical axis of the lens by decentering. CONSTITUTION:The inclination is given on an incident beam 105 of light on the wedge type prism 15, and it is image-formed on a disk 71 passing the objective lens 13. The prism 15 and the lens 13 are held integrally with a holder 113, and the optical axis 107 of the lens 13 is decentered against the rotating axis 109 of the holder 113. Therefore, the change of the inclination of the prism 15 is added on that due to the eccentricity of the axis 107 of the lens 13 by rotating the holder 113 by a micro amount centering the axis 109, which increases the amount of travel of a spot position on the disk 71. Therefore, a high shift quantity for the image-forming position can be obtained with a small amount of rotation of the holder 113. In such a way, it is possible to efficiently perform the control of the image-forming position in a tracking direction.
