IPC: H01L41/39
Filed: 1989-11-02
Abstract: PURPOSE:To reduce temperature dependency by sintering a specific laminated bonded body at a temperature which does not cause mutual diffusion among layers and by making an absolute value of a temperature coefficient of a frequency constant thereof smaller than an absolute value of a temperature coefficient of a frequency constant of any or either of layers. CONSTITUTION:Each layer of a laminated bonded body is formed by a green sheet of low temperature sintering PZT (lead titanate zirconate which is a two-element solid solution of lead zirconate and lead titanate) piezoelectric ceramics which can be sintered causing no or little mutual diffusion among layers; and one layer thereof is formed by a green sheet of PZT piezoelectric ceramics whose positive and negative of a temperature coefficient of a frequency constant are different from positive and negative of a temperature coefficient of other layers. The laminated bonded body is sintered at a temperature which causes no or little mutual diffusion among layers. It is constituted so that an absolute value of a temperature coefficient of a frequency constant thereof is smaller than an absolute value of a temperature coefficient of a frequency constant of any or either of layers. Thereby, temperature dependency of piezoelectric body can be reduced.

Title: Voltage controlled oscillator
Inventor: MASUMOTO NOBUSUKE
IPC: H03B5/12
Filed: 1992-10-26
Abstract: PURPOSE:To unnecessitate the setting of an oscillation frequency range from the outside or the adjustment of the lower limit and upper limit of each oscillation frequency range by automatically controlling a switching signal for the oscillation frequency range of the voltage controlled oscillator inside a system. CONSTITUTION:When there are the two steps of the current oscillation frequency range and a control voltage VT is equal to a threshold value VT1, for example, the oscillation frequency range is turned to three steps and lowered by oscillation frequency range switching elements 12 and 13. When the control voltage VT is equal to a threshold voltage VT2, the oscillation frequency range is increased by turning the oscillation frequency range to the first step. Namely, the oscillation frequency range of the voltage controlled oscillator is set by inputting a control voltage 4 and a threshold voltage 7 to a voltage comparator 8, inputting the output to a control circuit 9 and controlling the switching elements 12 and 13 with the circuit 9. Thus, since the oscillation frequency range of the voltage controlled oscillator is set, the oscillation frequency range can be automatically controlled over wide ranges inside the system without any control signal from the outside.

Title: Preparation of electrode foil for electrolytic capacitor
Inventor: KAGUMA KENJI
IPC: C25D11/24
Filed: 1987-11-13
Abstract: PURPOSE:To increase the capacitance after a formation treatment and to decrease both leakage current and dissipation factor (tandelta), by employing a series of processes in which after the pretreatment, in which a valve metal foil is boiled in an aqueous phosphoric acid solution, the valve metal foil is subjected to formation in a non-porous film forming electrolytic solution. CONSTITUTION:After an etched foil, for which an alumite treatment is performed in an oxalic acid(porous film forming electrolytic solution), is boiled in an aqueous phosphoric acid solution, the resulting foil is anodized in an electrolytic solution for anodic oxidation consisting of 5% boric acid and 0.03% ammonium borate(non-porous film forming electrolytic solution). A heat treatment is thereafter performed, and subsequently, a similar anodic oxidation in the same electrolyte and the following heat treatment are repeated three times. In such a way, both dissipation factor and leakage current are decreased by forming the porous film on the etched foil prior to the anodic oxidation. And, the phosphoric acid is made to remain in the porous film by boiling the etched foil with the porous film in the aqueous phosphoric acid solution, which results in the formation of the film which is difficult to hydrate. As a result, the energy necessary for the anodic oxidation is effectively decreased, and a stable and good quality anodic oxide film is produced.

Title: Vibration proofing rubber device
Inventor: MARUYAMA MASUO
IPC: G11B33/08
Filed: 1985-12-20
Abstract: PURPOSE:To prevent characteristic frequency from being changed by the passage of time by providing the titled device with vibration proofing rubber and a metallic spring having resiliency capable of supporting a body to be supported and setting up characteristic frequency based upon the spring itself and the body to be supported to a value lower than that based upon the rubber and the body to be supported. CONSTITUTION:The resiliency of the coil spring 2 is set up equally to the weight of the body 6 to be supported, and at the time of rest, the weight of the body 6 to be supported does not affect the vibration proofing rubber 1. The characteristic frequency based upon the coil spring 2 and the body 6 to be supported is set up so as to be lower than that based upon the rubber 1 and the body 6 to be supported. Since the dynamic spring constant of the rubber 1 is smaller than that of the spring 2, vibration applied to a rubber holding fitting 1 mainly acts upon the rubber 1 and the characteristic frequency and a resonance value as the vibration proofing rubber device are almost the same values as the ones based upon the rubber 1 and the body 6 to be supported.
