Title: Semiconductor device
Inventor: YAMAZAKI YASUO
IPC: H01L21/60
Filed: 1990-09-28
Abstract: PURPOSE:To make possible a substantial reduction in connection defects between a semiconductor device and a printed circuit board and prevent the destruction of semiconductor devices by forming electrodes which are hollow, sponge-type, or protrusions of the resin layer to reduce the weight applied to the semiconductor device during mounting of the semiconductor device on a printed circuit board. CONSTITUTION:After coating the active surface of a semiconductor device l with an epoxy adhesive 9 and aligning the protrusion electrodes 5 on the semiconductor device 1 with the interconnection patterns 8 on a printed circuit board 7, pressure is applied to the semiconductor device 1 and while the protrusion electrodes 5 are deformed, the semiconductor device 1 is heated and the adhesive 9 is hardened. Since the protrusion electrodes 5 have a hollow area 6, it is possible to achieve deformation with 1/4-1/2 the weight which is required to deform conventional, solid metal bumps and to absorb shock weight that impacts the semiconductor device 1 during mounting. As a result of being able to deform the protrusion electrodes 5 with less pressure, the problems of cracking or edge chipping of the semiconductor device 1 are eliminated, variation in the height of the protrusion electrodes 5 is absorbed by deformation of the protrusion electrodes 5, and no connection defects are observed.

Title: Optical disk with copying preventing pattern and its reproducing device
Inventor: KATO KAZUHO
IPC: G11B7/24094
Filed: 1994-09-29
Abstract: PURPOSE: To prevent an unauthorized copying by adding a copying preventing pattern P which does not affect the reading of a pit column and can not be detected by copying to an optical disk and prohibiting the reproducing of an optical disk for which the pattern P is not detected. CONSTITUTION: A copying preventing pattern P of a transparent ink layer 6 is printed on a laser beam incident surface 8 of a transparent substrate foundation section 7a and a laser beam 10 is focused on a recording information surface of a reflecting film 9 at a point 'a'. At that time, a beam image B becomes a circle on a 4D-PD3, a focus error signal 4 becomes zero volt. If the beam 10 is located at points 'b' and 'd', the focusing is deviated by the thickness of the layer 6 and the image B becomes an ellipse, short longitudinally and long laterally. Therefore, the signal 4 fluctuates between plus and minus voltages. If the beam 10 is located at a point 'c', the image B becomes a circle by a focus servo circuit and the signal 4 returns to zero volt.  The fluctuation of the signal 4 is demodulated, the pattern P is detected, an optical disk for which the pattern P is not detected is discriminated as an unauthorized copy and the reproducing operation is prohibited. Thus, an unauthorized copying is prevented.

Title: Gas insulated potential transformer
Inventor: HIGAKI SHIGEO
IPC: H01F27/02
Filed: 1984-12-08
Abstract: PURPOSE:To prevent entrance of the external air into an exclusive tank even in case a pressure tank is opened, by providing an exclusive tank having a hermetically sealed structure which is resistive to a little pressure difference and valves communicating with internal and external sides and also providing a gas insulated potential transformer. CONSTITUTION:A gas insulated potential transformer 3 is previously filled with insulation gas and is stored under the condition that an automatic valve 7 is closed. At the time of assembling, the transformer 3 is housed together with an exclusive tank 2 within a pressure tank 1. After the assembling of interior, the tank 1 undergoes sealing, vacuum exhaustion and supply of gas. Namely, in the case of vacuum exhaustion, the valve 7 operates and opens depending on a pressure difference between internal and external pressure. Therefore, an excessive pressure difference is not applied on the tank 2. For the supply of gas, the valve 7 operates and opens depending on the pressure difference when the tank 1 is filled with the insulation gas, the insulation gas flows into the tank 2 from the tank 1, not generating an excessive pressure difference. Thereby, the transformer 3 holds initial insulation performance and it is enough for the tank 2 to have the sealed structure which is resistive to an internal and external pressure difference of about 0.3-0.4kg/cm<2>.

Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To appropriately drive both different mechanisms by using one electric motor by supplying a different power per unit time to the electric motor in the case where the motor is rotated forward and in the case where the motor is rotated backward. SOLUTION: In the case of rotating a collapsible drive ring, a current having a positive polarity is intermittently supplied to the electric motor so as to rotate the electric motor forward(A). On the other hand, in the case of driving a film developing/discharging mechanism so as to discharge a film, a DC current having the polarity opposite to the aforesaid polarity is supplied so as to rotate the electric motor backward(B). First, the driving current level L of the electric motor is set to a level suitable for the film developing/discharging mechanism which is driven in accordance with the backward rotation of the electric motor. In the case of the forward rotation, the current is intermittently supplied to the electric motor, the power which is supplied to the electric motor per unit time is reduced lower than that in the case of the backward rotation.  Thus, a torque required for the operation of a lens barrel driving mechanism is thoroughly imparted and also the noise generated at the operating time is suppressed at a low level.

IPC: H03B19/14
Filed: 1991-10-08
Abstract: PURPOSE:To reduce the mount area of a band pass filter and to facilitate the circuit integration and monolithic processing by forming the band pass filter with a capacitive element and an inductive element of lumped constant type. CONSTITUTION:An output signal of a FETQ1 includes a 1st frequency f1 component and a 2nd frequency f2 component resulting from multiplying the 1st frequency component. The impedance of a band pass filter 1 between its input terminal and its ground potential point is 0 with respect to the frequency f1 component by an inductive element L2 and a capacitive element C2. Thus, the frequency f1 component does not appear at an transmission. On the other hand, the impedance between the output terminal and the ground potential point is infinite by the parallel resonance of an element L2, and elements C2, C1 to the frequency f2 component. Thus, the frequency f2 component appears at the output terminal as it is and a signal Vout including only the desired frequency f2 component is obtained.
