Title: Frequency adjustment method for tuning fork type crystal oscillator
Inventor: WAKASUGI MAKOTO
IPC: H03H3/04
Filed: 1978-01-13
Abstract: PURPOSE:To ensure the fine adjustment of the frequency in a simple way by adding or removing the material layer to or from part of the basement of the tuning fork of the oscillator. CONSTITUTION:To ensure the fine adjustment for the frequency, the laser trimming is given to the area where the amplitude is almost zero and the distortion is caused by the primary vibration of the oscillator such as part 7 of the basement of the oscillator, electrode film 6 of the area more close to the slit termination, or the layer of the additional material of the highly elastic metal, alloy or the like. With this method, the varying amount of the frequency can be minimized greatly in comparision with the change due to the additional mass. This minimized amount of variation is, however, is sufficient enough to carry out the accurate adjustment of the frequency. In this case, overlap thin film 4 can be omitted for the frequency adjustment.

Filed: 1983-01-10
Abstract: PURPOSE:To cast easily a hollow casting having composite structure consisting of ceramic particles and metal by casting the molten metal contg. ceramic particles from the tops of cores having semispherical top parts into a casting mold provided with said core in a central part. CONSTITUTION:Columnar cores 1, 1 having semispherical tops 1, 2 are erected in the central part of a casting mold 1, and a mixture L composed of particles P of ceramics having a large specific gravity such as WC or the like and a molten metal M are streamed downward onto the tops 1, 2 of the cores 1, 1 from the upper part. The mixture L disperses and flows uniformly downward from the tops 1, 2 over the entire circumference and accumulates in a hollow shape between the casting mold and the cores. The WC ceramic particles having the heavier specific gravity settle and form a composite casting together with the molten metal. The upper part where only the molten metal exists after settling of the WC particles plays the role of a riser for the lower composite casting. The composite casting part where the WC particles are uniformly dispersed and which is highly wear resistant, strong and tough is cut from the riser part and the hollow composite casting is produced.

Title: Latch-type circuit for detecting overcurrent
Inventor: ZAITSU TOSHIYUKI
IPC: H02H3/08
Filed: 1988-01-08
Abstract: PURPOSE:To simply manufacture a latch-type overcurrent detecting circuit being free from a detection loss, by a method wherein a current of a current wire to be measured is detected by SQUID and a detection signal is latched by Josephson FET. CONSTITUTION:When a current of IC flows through a current wire 1 to be measured, a current of KIC (K is a constant) flows through two-element SQUID 4, while a current of IB/2+KIC flows through a Josephson element 6. When a critical current of the element 6 is denoted by IO, a voltage is generated at the opposite ends of elements 5 and 6 when IB/2+KIC>=IO, and a gate voltage of Josephson FET 7 turns high. Thereby a critical current between the drain and the source of the FET 7 is reduced from IO to I'O. When a bias current becomes larger than the critical current I'O, a voltage is generated between the drain and the source of the FET 7, a terminal 8 turns high, and the terminal 8 continues latching with its level left to be high, even when the gate voltage of the FET 7 turns low.

Title: Waterproof case
Inventor: KAMATA KAZUO
IPC: G03B17/08
Filed: 1992-01-09
Abstract: PURPOSE:To simplify construction and to enable the regulation of the pressure in the case without necessitating a cost by forming an aperture in the case body having a perfect hermetic structure and covering the aperture with an air-permeable and water-impermeable sheet. CONSTITUTION:The air hermetically sealed into the waterproof case expands when the temp. around the case rises. This air passes a nonwoven fabric 17 and the air-permeable and water-impermeable film 18 and is discharged to the outside of the case body 9 from a hole 15 of the aperture 16 and, therefore, the pressure in the case body 9 does not rise and is kept constant. The waterproof case is sunk in water but the air-permeable and water-impermeable film 18 does not allow the passage of the water and, therefore, the water does not infiltrate the inside of the case body 9 at the time of underwater photographing. The air intrudes into the case body 9 from the outside thereof when the temp. around this waterproof case falls and, therefore, the internal pressure of the case body 9 is kept constant without dropping.
