An insulation layer 22 is a protective film for etching of the terminal 30. Moreover, Al2O3 and SiO2 are coated to form an insulation layer 22a. Through surface polishment, the surface of the lower magnetic substance layer 12 and the terminal 30 is exposed to make the surface flat. Next, the insulation layer is coated and the conductor is vapor-deposited on it to form a coil 14, a resin is coated to form flat surface and the said resin of the magnetic pole is etched for removal. Thus, problems such as thin film thickness and broken film can be avoided.

Title: Manufacture of flat type crystal oscillator
Inventor: MORI MASAMITSU
IPC: H03H3/02
Filed: 1981-04-24
Abstract: PURPOSE:To reduce the size of a flat type crystal oscillator by using an Ni- P plated film as an etching mask in half etching a glass base plate on which the quartz piece is to be mounted and thereby improving the accuracy of etching. CONSTITUTION:A thin metallic film easy to plate by vapor deposition or sputtering, for instance, CrAu 4, is formed on a glass base plate 1 and a half etching pattern is formed by photolithography. Then, several microns of Ni-P film high in chemical resistance is applied by electrolytic plating or nonelectrolytic plating. When etching of the glass is made next, an overhung part 5a is formed in the etching process of the base plate 1 and thereby renewal of etching liquid near 1b under the overhung film becomes poor and highly accurate product with small side etch similar to the mask pattern is obtained. Accordingly, the flat type crystal oscillator can be made small and thin easily.

Title: Circuit breaker
Inventor: SATO SAKANOBU
IPC: H02H3/093
Filed: 1994-03-31
Abstract: PURPOSE:To obtain a circuit breaker which can be used in common for load currents at different frequencies by a method wherein a digital signal value is squared and a processing operation which smoothes its operated value by a digital operation is performed at every sampling cycle. CONSTITUTION:A current transformer 5 detects a current, and it outputs an analog signal. A control device 6 controls a tripping operation on the basis of a digital signal which has been converted from the analog signal. At this time, the control device 6 performs an operation to square the value of the digital signal, and it performs a processing operation to smooth its operated result by a digital filtering operation at every sampling cycle. That is to say, whenever one piece of sampling data is acquired, a smoothing processing operation is performed. As a result, the squared value of input data is time-averaged sequentially, and an effective value as the time-averaged value of the signal- squared value can be found without depending on the frequency of the signal. Thereby, a circuit breaker can be used in common for load currents at 50Hz, 60Hz or other frequencies.

Title: Logic threshold matching method for lsi and electronic circuit device
Inventor: UCHIDA SATORU
IPC: H03K19/0175
Filed: 1991-03-04
Abstract: PURPOSE:To eliminate the need for a level shifter for logic threshold voltage matching by adjusting a voltage between a reference level in common to plural LSIs and a level at an LSI power supply terminal. CONSTITUTION:A 5V voltage is applied between terminals 3 and 4 of an LSI 1 with respect to a ground level GND (=0V) and the terminal 4 is set to the ground level. A rated voltage 3.3V is applied between power supply terminals 5 and 6 of an LSI 2. A voltage of 0.85V is applied to the terminal 6 of the LSI 2 with respect to the ground level and a voltage of 4.15V is applied to the terminal 5. In this case, the voltage applies between the terminals of the LSI 2 is set to 3.3V being the rated voltage. When a logic threshold voltage Vth is selected to be a half the voltage between the power supply terminals (=3.3/2+0.85)V, the logic threshold voltage Vth of the LSI 2 is set to 2.5V with respect to the ground level and it is coincident with the logic threshold voltage Vth 2.5V(=5/2) of the LSI 1. Thus, the level shifter for matching the logic threshold voltage is not required.

Title: Semiconductor device
Inventor: NAKAMURA YOSHINOBU
IPC: C08L33/02
Filed: 1985-03-27
Abstract: PURPOSE:To obtain an effect of absorbing and relaxing thermal stress, by sealing by the use of a resin composite material in which both a core, made of ester-(metha)acrylate resin having a glass transition temperature below room temperature, and corpuscles, formed by coating the peripheral surface of the core with an outer layer comprising specific polymer resin as basic resin, are mixed with epoxy resin. CONSTITUTION:Sealing is carried out by the use of a resin composite material in which both a core, made of ester-(metha)acrylate resin having a glass transition temperature under room temperature, and corpuscles of less than 15mum in diameter, formed by coating the peripheral surface of the core with an outer layer comprising polymer resin of unsaturated monomer as basic resin, with one reactive double bond making a glass transition temperature higher than 70 deg.C, are mixed with epoxy resin. When corpuscles are dried and powdered, it is desirable to set the composition weight % of the outer layer at 5-60% of all corpuscles weight, in order to prevent corpuscles from being mutually fusion-sticking and to complete powdering. The content of corpuscles included as dispersion phase in the resin composite material is 3-120wt.pt. against epoxy resin 100wt.pt. Thus, the sealed part comes to the completely high heat-resisting state of epoxy resin, and shows superior damp-proof and thermal shock-resistance due to the effect of absorbing and relaxing thermal stress by corpuscles, high reliability being obtained.
