Title: Electroplating apparatus
Inventor: INOUE KIYOSHI
IPC: C25D5/00
Filed: 1981-06-05
Abstract: PURPOSE: To obtain an electroplating apparatus, wherein a laser beam or the like is irradiated upon sections of a work to be processed and sections where electroplating will hardly take place, so that while the efficiency of electrodeposition to the irradiated areas is increased, selective partial electroplating is performed, or prescribed areas are electroplated by scanning.  
     CONSTITUTION: An Ni plating solution or the like that has been kept at room temperature or below is supplied as indicated at 1 to the work 3, while a pulse voltage with a prescribed polarity from an electric source circuit 18 is supplied across the work 3 and the electrode 17 to carry out the electroplating. During this period, the electroplating rate is set at a very low value, calculating from the relationship between the solution temperature and the voltage. The sections of the work 3 where plating is required are irradiated with a laser beam from a beam source 10 passing through the plating solution so that the plating solution adjacent the irradiated sections is heated to about 45W60°C to perform selective electroplating. Accordingly, for this electroplating rate, if motors 14, 15 and/or 16 are driven to drive the work 3 at a suitable rate, electroplating in accordance with the driven profile pattern can be carried out.

Abstract: PURPOSE: To find direct the base-band transmission characteristics of a longish ultra-broad-band and low-loss fiber, by discriminating a frequency in a frequency region by combining the sweep of a sweeper and a circumference method by using longish single-mode fiber.  
     CONSTITUTION: The photo signal of laser diode 3 is intensity-modulated by output signal (f 0 Hz) of oscillator 12 and supplied via photo branch coupling circuit 4 to fiber 5 of a measured object, where it cycles at a period of time (-) sec. Then, photo branch coupling circuit 6 extracts a photo signal which has cycled fixed times (n). Namely, when the oscillation frequency of local oscillator 21 is supposed to have intermediate frequency (fB), delay circuit 8 with delay time (n-) is provided between oscillator 11 and local oscillator 21 and the oscillation frequency of oscillator 21 at time (n-) becomes fB+f 0 . In this way, a signal of this frequency has its frequency changed into (f 0 ) by intermediate-frequency filter 23, which is utilized to find equivalently the transmission characteristics of longish fiber at frequency (f 0 ).

Abstract: PURPOSE:To facilitate an easy backward shift of a probe from outside and at a point of measurement which cannot be viewed by eyes, by using the same route for both the backword movement and the contact after a contact of the probe. CONSTITUTION:A contact route speed storage circuit 34 stores a prescribed amount of speed of the contact route through which a probe 14 touches an object 12 to be measured. A backward route speed commanding circuit 26 delivers the backward route speed signal 102 by an amount equivalemt to the prescribed backward shift and based on the contact route speed when the probe shifts backward.

Title: Ball-seat type solenoid two-way valve
Inventor: NONOYAMA YOSHIHARU
IPC: F02M47/00
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To prevent any uneven injection flow in an armature chamber in a ball seat type solenoid two-way valve even if coaxiality between a taper of a ball supporter and a seat angle is insufficient by preventing a ball valve from being laterally shifted. SOLUTION: A taper 34 serving as a ball supporter of a needle 29 is formed into a recessed taper having an angle greater than that of a valve seat 36, thereby preventing seat deficiency and valve closing deficiency. A needle inner low pressure passage 35 serving as a pore vertically penetrating the center of the ball supporter of the needle 29 is formed in such a manner as to communicate with a low pressure passage, so that fuel can be drawn from the needle inner low pressure passage 35 serving as the pore and the ball can be returned back to the center of the ball supporter when the needle 29 is lifted to laterally shift a ball.  Consequently, it is possible to prevent any uneven injection flow in an armature chamber in a ball seat type solenoid two-way valve by preventing the ball valve from being laterally shifted even if coaxiality between the taper of the ball supporter and a seat angle is insufficient.

IPC: H04B1/16
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To supply a currant from a power supply to a servo device while suppressing the loss of the current and to prevent the momentary interruption of the current. SOLUTION: A receiver main body 1a is connected between a power supply 2 and servo devices 3 through cables 4, 5. The receiver main body 1a has in its inside a switching section 8 that supplies the main current from the supply 2 to the servo devices 3 in response to the input of the input of a control signal. Furthermore, a power 11 is extracted to the outside of the receiver main body 1a and one terminal of the switch 11 is connected to the power supply 2 to obtain a very small shunt current branched from the current of the power supply 2.  A control circuit 14 receivers the branched current when the power switch 11 is closed to output a control signal with an integration waveform changing according to a desired time constant. that is, the servo devices 3 receive a current with less loss because of the absence of a switch and an extension cable causing a current loss between the power supply 2 and the servo devices 3. Moreover, even on the occurrence of chattering of the power switch 11, the momentary interruption of the current can be prevented.

Title: Photochemical device for gaseous phase growth
Inventor: MINAKATA MAKOTO
IPC: C23C16/48
Filed: 1982-05-24
Abstract: PURPOSE:To obtain a high purity membrance by collecting at the center of a reaction vessel a light source with an absorption wave length of a raw material gas and a reaction gas and allowing both to react photochemically in multiple stages. CONSTITUTION:If a reaction gas 20 is introduced into a reaction tube 17, the inside pressure increases because of the small blowing hole 18, making the area near the center shaft of a vessel 11 have a high concentration. A light 22 from a laser light source 21 with wave length that makes photochemical reaction with the reaction gas is collected at the center of the reaction tube 17 by means of a cylindrical lens 23. Since the vessel 11 and the reaction tube 17 are coaxial, the light 22 is reflected by reflection mirrors 12A and 12B and proceeds in the longitudinal direction of the tube and has a maximum density on the center shaft. The magnitude of the density is adjusted by the laser output and the incidece angle to the reaction tube, and acts in a long distance until the light energy is completely absorbed into the gas. Decomposed high energy gas is projected on to a substrate 14 from a hole 18 to form a thin film 28. By selecting an appropriate wave length of the laser light source 24 and collecting and focussing an irradiated light 25 on the substrate 14, a pure thin film of any pattern can be formed by a low temperature of the substrae.
