Title: Piezoelectric resonator
Inventor: IRIE MAKOTO
IPC: H03H3/04
Filed: 1990-08-21
Abstract: PURPOSE:To adjust the oscillating frequency simply and accurately by adhering a resin including dielectric powder between an end electrode and an intermediate electrode on an outer face of a dielectric base. CONSTITUTION:A resin 11 including dielectric powder is adhered to a part between an end electrode 8 and an intermediate electrode 9 on an outer face of a dielectric base 6, and the oscillating frequency is adjusted by increasing a load capacitance formed to the part between the end electrode 8 and the intermediate electrode 9 of the dielectric base 6 through the adhesion of the resin 11. The adhesion of the resin 11 onto the dielectric base 6 is implemented by printing or coating so as to allow the resin not to be in contact with the end electrode 8 and the intermediate electrode 9, and the load capacitance between the end electrode 8 and the intermediate electrode 9 of the dielectric base is freely increased through the selection of the adhered area and the adhered thickness. Thus, the oscillating frequency is minutely adjusted in the decreasing direction.

Title: Semiconductor integrated circuit
Inventor: EBIHARA TAKASHI
IPC: G11C11/419
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To correct a step-down power supply line to normal potential even when the step-down power supply line is excessively charged by overdrive operation by making different the size of at least one of transistors for composing first and second differential amplifies between the first and second differential amplifiers. SOLUTION: When the potential of a node N2 of a differential amplifier PL rises, current that flows to a negative-side input transistor in the differential amplifier PL is increased, thus increasing the current of a transistor Q6, and pulling out a VDH. A reference voltage is set to VLH/2, and feedback from the VDH is also set to the half of the VDH by voltage divided by a resistor, and is inputted to the gate of the input transistor in the differential amplifier PL, thus the driving capability is secured, and a stabilized operation can be obtained. A p-MOS is used for a transistor for pulling out, an n-MOS is used for a transistor for charge driving, and source follower connection is made, thus decreasing a loop gain, increasing a phase margin, and hence overshooting is prevented.

Title: Liquid crystal display device
Inventor: ARAI KAZUO
IPC: G02F1/1335
Filed: 1985-10-04
Abstract: PURPOSE:To obtain a good image of high contrast and wide visual field angle even in the higher time division driving system by specifying the twist angle of liquid crystal molecules, the direction of the axis of polarization of a polarizing element, and an angle between the surface of each of a pair of substrates and the direct position of liquid crystal molecules brought into contact with the surface. CONSTITUTION:A twist angle alpha of liquid crystal molecules in the liquid crystal composition arranged between a pair of substrates 1 and 2 is >=180 deg. and <=360 deg., and the direction of the axis of polarization of the polarizing element has >=70 deg. and <=110 deg. shift angles beta and gamma in the twist direction of liquid crystal molecules with respect to the director direction of liquid crystal molecules brought into contact with the surface of the substrate in the polarizing element side, and the angle between each of the surface of a pair of substrates and the director direction of liquid crystal molecules brought into contact with the surface is <=5 deg.. If the twist angle alpha is >360 deg., the change of the intensity of a transmitted light for an impressed voltage is gentle and the response characteristic is insufficient; and if it is <180 deg., the malfunction of turn-on and off is apt to occur for time division driving. If shift angles beta and gamma are deviated from said range, the change of the intensity of the transmitted light for the change of the impressed voltage is gentle and the response characteristic is low.

In the same manner, while the rotor 1 is being turned at low speed, a half pierced part 3 is detected by a laser sensor 10. The accuracy of the ignition time can be judged on the basis of the detection value of the half pierced part 3. Whether a generated voltage and the ignition time are good or not is judged on the basis of its judgment.  When they are good, a type number, a manufacturing data and a serial number are marked continuously by an ink-jet printer 11 in a state that the rotor 1 is placed on the shaft.
