Filed: 1979-07-04
Abstract: PURPOSE: To increase strength and to reduce cost, when an epoxy resin etc. is used for construction work, by use of a light, granular calcined clay mineral as a bulking filler.  
     CONSTITUTION: In using urethane or epoxy resins in construction work, a granule is produced by coating a hollow nucleus, obtained by the expansion of a finely granulated rock at a temperature ≥900°C, with a homogeneous powder, mixture consisting of a particulate clay mineral such as clay, talc or diatomaceous earth, and of bentonite and water. The granule is calcined at 800W1,200°C, to produce a light bulking filler, which is blended with urethane- or epoxy resins in a desired amount, and used as a void filler, etc., for construction work. Excellent strength is obtained, because of the uniform distribution and intimate adhesion to the resin, of the calcined granule.

Title: Detector for quantity of shift
Inventor: UTAGAWA TAKESHI
IPC: G02B7/34
Filed: 1985-04-22
Abstract: PURPOSE:To detect the quantity of the shift of an image of even a pattern having small contrast effectively by providing an optical means, a photoelectric converting means, a correlation arithmetic means, an interpolating means, a decision means, and a correcting means. CONSTITUTION:The optical means 100 forms a couple of light images of the nearly the same objects. The photoelectric converting means 101 includes the 1st and the 2nd photoelectric element arrays 102 and 103; the array 102 photodetects and converts one of both light images from the means 100 photoelectrically and the array 102 photodetects and converts the other photoelectrically. The correlation arithmetic means 104 shifts each photoelectric output of the array 102 for each photoelectric output of the array 103 and calculates the quantity of correlation between both output patterns. The interpolating means 105 interpolates plural quantities of correlation from the arithmetic means 104 to find an extremal value and the quantity of a shift corresponding to it. The correcting means 106 makes a correction so that an electric noise component does not exert any influence when the decision means 107 performs decision operation. The decision means 107 when the extremal value is less than a specific value makes the interpolated shift quantity corresponding to the extremal value into a signal indicating a focus adjustment state or object distance.

Title: Speaker device
Inventor: OYABA TAKASHI
IPC: H04R3/12
Filed: 1989-04-06
Abstract: PURPOSE:To eliminate the effect of a reflecting tone with simple constitution by in stalling two speakers subjected to band split onto a perpendicular line so as to cause a wide trough on the synthesis sound pressure frequency characteristic with the reflecting sound only thereby making the frequency characteristic of the direct sound flat. CONSTITUTION:A 2nd speaker SP2 with a high sound frequency apart by a half the wavelength of a crossover frequency is arranged to a 1st speaker SP1 with a low sound frequency arranged close to a reflection face Re in an orthogonal direction. Then the frequency characteristic of the synthesized sound pressure from virtual sound sources SP1', SP2' being the reflecting sources of both the speakers SP1, SP2 causes a wide trough at the crossover frequency and the frequency characteristic of the synthesized sound pressure of direct sounds is made flat by using a band split filter. Thus, the change in the overall sound pressure frequency characteristic is decreased independently of the presence or absence of the reflection with simple constitution to obtain excellent reproduced sound.

Title: Control circuit for switching element
IPC: H03K17/04
Filed: 1992-03-09
Abstract: PURPOSE:To reduce the cost of the circuit by decreasing a turn-off loss of the switching element and to reduce the size of its heat sink. CONSTITUTION:The control circuit is provided with a switch 7 detecting a voltage between a source of a power MOSFET 1 being a switching element and a ground terminal of the control circuit 4 and short-circuiting the gate and source of the FET 1 when the voltage reaches a prescribed voltage. Thus, even when a voltage is generated by an electromotive force by an inductance at turn-off, since the gate-source of the FET is short-circuited, a delay in turn- off is reduced and the loss is reduced. Thus, the size of a heat sink for the switching element is made small.
