Title: Method of making through-hole on copper-plate sheet by laser
Inventor: TAKE MORIO
IPC: B23K26/00
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To provide a method of making a through-hole having a small diameter accurately at a high speed by irradiating a copper-plated sheet with a high- output CO2 gas laser. SOLUTION: In a method of making a through-hole by using energy selected from 20-60 ml/pulses sufficient for removing a copper foil by CO2 gas laser and machining the copper foil of a copper-plated sheet having at least one or more copper layers, a laser backup sheet, in which the thickness of a resin layer is 20-200 μm at least on the face in contact with the copper foil, is arranged on the copper foil of the outermost layer on the side opposite to the surface which is irradiated with CO2 gas laser, of the copper-plated sheet; and drilling is performed while a metallic sheet suitably having a luster on the surface is placed in such a manner as to be in contact with the backup sheet or suitably in adhesion to it by lamination.  As a result, a through-hole can be made at high speed which is accurate in the hole position on the front and the rear and which is superior in the shape, enabling a through-hole improved in cost performance in the formation and suitable for a printed circuit board of high density.

Title: Telescopic pole driving device for vehicle
Inventor: YOSHIDA KOICHI
IPC: H01Q1/10
Filed: 1988-07-06
Abstract: PURPOSE:To automate the driving and stopping of a telescopic pole by installing a built-in switch which automatically opens and closes, using a relative rotation between a winding drum which gives telescopic motion to telescopic poles like a corner pole and the center gear which drives the winding drum. CONSTITUTION:When an indoor switch 1 is changed over, for an example to an up-side each contact point, P1 and P2, are connected so that the electric current from a battery B is flown to each contact point, P1 and P2, a motor M, a relay contact point S and a contact point b. The motor M therefore rotates clockwise to extend a telescopic pole. When the telescopic pole is extended to its full length, a built-in switch SW2 is turned on and a light emitting diode D2 lights up simultaneously. As the electric current from the battery B flows to the contact point P1, a relay coil L, the built-in switch SW2 and the diode D2, a relay R is turned on to switch over the relay contact point S to a contact point a. As the result, both ends of the motor M are short-circuited to stop the motor M.

Title: Deflection coil
Inventor: YOSHII MASAAKI
IPC: H01J29/76
Filed: 1990-06-28
Abstract: PURPOSE:To provide a magnetic field distribution which is not obtainable by usual coiling method, by allowing a plurality of coil parts to generate a specific deflection magnetic field for deflection of a beam, dividing the coil parts into No.1 and No.2 region, and equipping each region with parts where the current directions become opposite to one another. CONSTITUTION:If a part is formed where one turn of coiling is completed only within one of the regions as shown by Point A to B and Points C to D by way of example, a current direction iR can be obtained in each region, which is opposite to the normal current direction iF in the case one turn is wound across from No.1 to No.2 region. This does not require reversal with the coiling direction inverted. Thereby a magnetic field distribution becomes obtainable, which has been difficult according to the conventional techniques, and the degree of freedom in setting the mag. field distribution is extended largely. Further when the convergence characteristics are to be improved through mag. field distributing action of a deflection yoke, its correction can be made more effective.

Title: Detector for material with different diameter
Inventor: YAMADA NAOTO
IPC: G01B5/08
Filed: 1983-09-13
Abstract: PURPOSE:To easily detect a different-diameter material such as a tube and a round rod by fitting a contactor atop of an arm, and bringing it into contact with the tube or round rod and detecting the angle of rotation of the arm. CONSTITUTION:When the tube or round rod 2 having a necessary external diameter passes through the position of the contactor 11 in a stand-by state, an actuator 15 operates to bring the contactor 11 into contact with the tube or round rod 2, and it is judged that the material has the necessary external diameter from the position relation between a rotating disk 6 and detectors 7, namely, when only the signal from the lower detector 7a varies. When the material is a tube or round rod (9a) having a large external diameter, neither of signals from both detectors 7 varies. When the material is a tube or round rod (9b) having a small external diameter, on the other hand, the signals from both the upper and lower detectors 7 vary. Thus, a deformed material such as a tube and a round rod is detected easily.

IPC: H05G1/18
Filed: 1981-10-23
Abstract: PURPOSE:To control the magnitude of a superposed voltage by allowing the voltage which possesses the reverse polarity for offsetting the pulsating voltage to be superposed onto the output of a rectifying circuit, offsetting the pulsating voltage contained in the output voltage and detecting the input voltage in order to suppress the pulsating voltage due to the unbalance  relative to the input voltage, with regard to control of a DC power apparatus in low pulsation  which is used for an X-ray generator.

Title: Speech recognition device
Inventor: SUGIURA HISASHI
IPC: G10L15/24
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To achieve an improvement in a speech recognition rate and to provide a more user-friendly speech recognition device by eliminating as much as possible noise components from an input signal in which a speech to be recognized and noise are mixed. SOLUTION: While a PTT switch is being pushed, an inputted speech is accepted as a recognition object. Therefore, recognition processing has to be executed only for an input signal required for speech recognition, and this reduces a load of processing. And, this speech recognition device is arranged so that it takes in noise signal during a predetermined period after the PTT switch is switched off and an input period specified by a user has expired. As a result, even if the user utters a speech immediately after the PTT switch is switched on, it is possible to estimate secured noise components and surely extract a speech by taking in the input signals in the noise period after the end of the input period. Thus, user is not specially restricted about a speech input but free from any consciousness.
