IPC: H01L21/683
Filed: 1988-03-11
Abstract: PURPOSE:To prevent the breaking of a cushioning material while preventing the generation of the cracking of a wafer by forming a notch section at an end section on the side near the central section of the wafer in the underside of a fastener and making the depth of the notch section larger than the thickness of the cushioning material and smaller than the sum of the thickness of the wafer and the thickness of the cushioning material. CONSTITUTION:Notch sections 10' are shaped at end sections on the sides near the central section of a wafer in the undersides of fasteners 10 to a stepped form. Depth D in the direction of the thickness of the wafer of the notch section 10' is set so as to be made larger than the thickness of a cushioning material 3 and smaller than the sum of the thickness of the wafer 4 and the thickness of the cushioning material 3 at that time. When the wafer 4 is loaded onto the cushioning material 3, the wafer 4 can be fixed under the state in which the bases of the notch sections 10' for the fasteners push the top face of the outer circumferential end of the wafer. The nose surfaces of the fasteners are stopped under the state, in which the nose surfaces are abutted against the top face of a sample base 2, under the state in which the wafer 4 is not loaded, and the fasteners are not brought into contact with the cushioning material 3 in the presence of the notch sections 10'. Accordingly, the cushioning material 3 is at broken, and the wafer 4 is not cracked, thus improving the yield of chips acquired from the wafer 4.

Title: Electric hot-water heater
Inventor: SEKOGUCHI YOSHINORI
IPC: F24H1/10
Filed: 1991-02-27
Abstract: PURPOSE:To improve safety by a method wherein a switch for a safety circuit is placed under a pressure sensor at a specified distance, the safety circuit is situated between the pressure sensor and a microcomputer, and a motor is brought in operation only when the switch is closed by pressing a hot-water delivery button. CONSTITUTION:When a hot-water delivery button 50 is not pressed, a high level signal is input to an input port PI1 of a microcomputer 60 by a resistor 39, and an open signal is input to an output port PO0. Thereby, the base potential of a driving transistor 17 for an electric motor 19 becomes low level, and the motor 19 is not operated. When a tact switch 73 of a pressure sensor 51 is pressed by the hot-water delivery button 50 and an ON signal is input to an input port PI2, the microcomputer 60 outputs open signals to output ports PO1-PO4 corresponding to voltage value that is input to the input port PI1. Thereby, the base voltage of the transistor 17 is set at a specified one, and the motor 19 rotates at a specified rotating speed to deliver hot-water.

Title: Monovalent copper analysis
Inventor: TAZAKI SHINJI
IPC: G01N21/27
Filed: 1993-02-24
Abstract: PURPOSE:To provide a method wherein monovalent copper is analyzed by a simple method without being oxidized. CONSTITUTION:In the alcohol solution of neocuproine or bathocuproine, monovalent copper preferentially forms a complex with the neocuproine or the bathocuproine even under the air, and the complex which has once been formed exists comparatively stably. Consequently, a solution which contains the monovalent copper is injected into the alcohol solution of the neocuproine or the bathocuproine, the complex with the monovalent copper and the neocuproine or the bathocuproine is formed, and the solution containing the complex is extinction-analyzed. When bivalent copper coexists in a measuring solution, there is a fear that the bivalent copper disturbs the color formation of the monovalent copper. As a result, it is preferable that a substance which forms a complex with the bivalent copper such as histidine, histamine, EDTA or the like is added as the masking agent of the bivalent copper.

Title: Local control type fet data switch for semiconductor memory cards
Inventor: PAUL WILLIAM CORTIAS
IPC: G11C5/00
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To improve the speed of a memory data bus connecting many memory cards by comprising a plurality of electronic devices disposed to electrically communicate with printed circuit cards through switches and enable lines electrically interconnecting switches corresponding to the plurality of electronic devices to provide enable signals to the switches. SOLUTION: An FET enable line 310 is directly connected to a memory device 330, resistor 320 and then ground. The resistance value of the resistor 320 is large enough to quickly restore a switch enable to the ground when no memory device asserts the FET enable line 310. When the FET enable line 310 is released from assert, the memory device 330 first drives the FET enable line 310 to the ground and then the switching can be sped up when the FET enable line 310 is released.

Title: Semiconductor integrated circuit device
Inventor: ARITA YUTAKA
IPC: H01L21/60
Filed: 1988-03-11
Abstract: PURPOSE:To reduce input capacitance by providing a P-N junction region to the lower section of a bonding pad. CONSTITUTION:An silicon oxide film 2 is shaped onto an silicon substrate 1, and a bonding pad 3 is formed onto the silicon oxide film 2. A passivation film 4 composed of the silicon oxide film or a nitride film is shaped around the bonding pad 3. A diffusion layer 5 containing a P-type impurity in low concentration and showing a conductivity type reverse to the silicon substrate 1 is formed to the silicon substrate 1 in the lower section of the bonding pad 3, and a P-N junction is shaped between the silicon substrate 1 and the diffusion layer 5 by the diffusion layer 5. The capacitance of the bonding pad 3 is represented by the synthetic capacitance of the capacitance C1 of the film 4 and the capacitance C2 of the substrate and the diffusion layer 5 because the N-type substrate 1 is connected to a power supply. Since synthetic capacitance C is diminished with the reduction of capacitance C2, the capacitance of the bonding pad 3 is decreased with the lowering of an impurity in the diffusion layer 5 and the increase of reverse bias voltage VR, thus lessening the capacitance of the bonding pad 3.
