Title: Hammer drill
Inventor: JIYOSUWARI MOHAMEDO
IPC: B25D16/00
Filed: 1994-06-09
Abstract: PURPOSE:To provide an operation mode switching device for a hammer drill resolving the problems that the pin shaft of a switching lever is abraded in the operation mode of 'rotation only' and impact force is applied to a tool and having a simple structure and good operability by holding the inner ring of a reciprocating bearing and a clutch with a fixed member. CONSTITUTION:A reciprocating bearing 4 and a clutch 5 are invariably coupled. When the clutch 5 is moved in the axial direction, the coupling between the clutch 5 and an intermediate shaft 3 is released, the rotation transmission to the clutch 5 is insulated, and the abrasion of the pin shaft 6a of a switching lever is reduced. Since a fixed member 7 holding or pinching the clutch 5 or blocking the rotation of the crutch 5 in the operation mode of 'rotation only' is provided, no impact force is applied to a tool 14 due to the sliding friction of the reciprocating bearing 4 in the operation mode of 'rotation only'.

Abstract: PURPOSE:To eliminate a blooming phenomenon and obtain an excellent image plane by making the impressed voltage to a light transmissive electrode film smaller than the impressed video voltage to the reverse surface of a photoconductive thin film and either larger than the built-in voltage of a diode provided on a semiconductor substrate or equal to its reverse voltage value. CONSTITUTION:The photoconductive thin film 5' is formed of amorphous silicon to a 500Angstrom -5mum film thickness and the light transmissive electrode film 7 is formed on SnO2 to 1,000Angstrom -2mum. A switch circuit is driven with a driving pulse with, for example, a 7V amplitude and a video bias voltage 5V is applied to a signal output line 10-2. The light transmissive electrode film is connected to the same earth voltage VT=OV with the substrate. The built-in voltage VB of the diode is about 0.7V and then VT is set to OV so as to give a margin to a lower voltage, e.g. VT at which blooming begins to occur. Thus, VT is set and the blooming is prevented up to the quantity of light about 200 times as large as in case of saturation.

Title: Pattern detection method of printed board for lamination
Inventor: ANDOU SANETOSHI
IPC: G01B11/24
Filed: 1978-10-20
Abstract: PURPOSE: To detect the existence of defects in the pattern on the printed board accurately with ease by scanning a laser beam on the printed board and then detecting the transmitted beam through a collector which it is led to enter.  
     CONSTITUTION: A laser beam emitted from a laser generator 5 is focused through a lens system 6 and a reflection mirror 7 to irradiate on a substrate 2 having a portion of pattern 4 on the back. The laser beam is dispersed in the substrate 2 and penetrates the substrate 2 from outside the pattern. The transmitted beam is collected with a collector 8 and enters a light detector 9, which detects the beam and sends the output signal to an amplifier 10. The output signal is amplified by an amplifier 10 and measured with an output observing detector. With such an arrangement, when defects exist in the pattern, the laser beam penetrates them and presents an abnormal measured value. Thus, the existence of the defects can be detected accurately with ease.

Title: Manufacture of josephson element
Inventor: ENOHARA AKIRA
IPC: H01L39/24
Filed: 1993-05-31
Abstract: PURPOSE:To form a Josephson junction by a method wherein the superconducting characteristics of a metallic oxide superconducting thin film are partially controlled. CONSTITUTION:A metallic oxide superconducting thin film 2 is formed on a dielectric substrate 1 consisting of MgO, LaAlO3 or the like. When a YBa2Cu3Ox or Bi2Sr2Ca2Cu3Ox superconducting material is used as the thin film 2, a thin film of high quality can be easily formed by a high-frequency sputtering method, a laser abrasion method or the like. After the thin film 2 is thus formed and hydrogen ions are emitted to two terminal parts 4 and 4 split by a fine gap part 3, an oxidation treatment of the thin film 2 is performed. A Kaufranm ion source is used for the emittion of the hydrogen ions and the emission is performed for about 20 minutes in a vacuum at an ion accelerating voltage of 1kV and with an ion current density of 10<-4>A/cm<2> or thereabouts.

Title: Method of electron beam exposure
Inventor: TANAKA KAZUMITSU
IPC: H01L21/027
Filed: 1980-09-17
Abstract: PURPOSE:To expedite the exposing speed by setting the timing of the stage movement in the exposing method in which the stage is intermittently moved so as to obtain the minimum time for protecting a vacuum sealing part, and eliminating unnecessary stationary time. CONSTITUTION:The stage 1 on which material to be exposed 2 is intermittently moved by an external driving mechanism in a vacuum container 5 through a shaft 4 by way of the vacuum seal 6 at every exposure stage. The driving mechanism 3 comprising a pulse motor and the like is controlled by a control circuit 7 which receives signal from a computer 8. In the case the exposing time for the movement of the stage 1 varies, the circuit 7 inspects whether one short pulse having a time length T which has risen up at the last stop falls or not, upon receiving the movement starting instruction from the computer 8. The value of T is made to be the minimum for preventing the burning of the seal 6. If the pulse has fallen, the circuit immediately supplies the driving signal. If the pulse does not fall yet, the circuit waits until the pulse falls, and supplies the driving signal after the fall. Therefore the overall exposing speed can be expedited.

Title: Automatic clock switching system and its circuit
Inventor: NAKAMURA MASAKAZU
IPC: H03K17/00
Filed: 1992-05-21
Abstract: PURPOSE:To switch a working clock to a stand-by clock without generating a hazard by detecting an OFF level state also simultaneously with OFF detection when the working clock is turned off CONSTITUTION:When a clock CKA OFF detecting circuit 1 or a clock CKB OFF detecting circuit 2 detects the generation of clock OFF, an automatic clock switching display part 3 detects whether the OFF clock is a working clock or not by comparing the detected result with the set state of a manual switching signal SEL. On the other hand, an OFF clock 'H' level fixing detecting part 4 detects which level, 'H' or 'L', turns the working clock turned off to an OFF fixed state. A clock switching control part 7 generates a switching command signal at a position where the level of a stand-by clock coincides with that of the OFF working clock and controls a clock selector 8, so that the working clock is automatically switched to the stand-by clock.

Title: Exciting method for linear step motor
Inventor: OGIRI KIYOHIRO
IPC: H02P7/00
Filed: 1986-06-02
Abstract: PURPOSE:To reduce damped oscillation in case of the stoppage of a needle by alternately exciting a four-phase linear stepping motor in two-phase excitation and three-phase excitation. CONSTITUTION:The first phase phi1, second phase phi2 and fourth phase phi4 of a stator 10 are excited. Consequently, the teeth of a needle 20 are faced oppositely to the magnetic core of the first phase phi1 of the stator 10. The first phase phi1 and second phase phi2 of the stator 10 are excited. As a result, the needle 20 is moved at a 1/8 pitch to the right side. The first phase phi1, second phase phi2 and third phase phi3 of the stator 10 are excited, and the needle 20 is further shifted at the 1/8 pitch in the right direction. Accordingly, the stator is excited by alternately repeating two-phase excitation and three-phase excitation, thus increasing the mutual suction force of the needle and the stator at a time when stopping the needle.
