Title: Manufacture of semiconductor device
Inventor: FUKUZAWA TAKESHI
IPC: H01L21/3205
Filed: 1988-07-05
Abstract: PURPOSE:To prevent lowering of a yield rate of semiconductor chips by removing the second resist pattern which is used for hindering the selective removal by means of ion milling and the like at the peripheral part of a semiconductor wafer. CONSTITUTION:After coating the whole surface of a semiconductor wafer with a positive resist material, first of all, exposure is conducted to respective chip formation parts 2 on the semiconductor wafer 1 and then, extensive exposure is carried out to a peripheral part 3 as indicated by a shadowed part 4. As the positive material on the peripheral part 3 of the wafer 1 is exposed sufficiently, all the positive material on the peripheral part 3 is removed by development. Since an electric conduction material 17 of the peripheral part 3 is removed by subsequent ion milling, the electric conduction material does not scatter when dicing is performed.

The length of the recessed part 2 is made coincident with the length of the circuit board 4, the width is made wider than that of the circuit board 4, and the recessed part is planarly formed. At both the side wall parts of the recessed part 2, flanges 7 and 7 are provided at the height almost equal with the thickness of the circuit board 4 from the bottom parts and further, a lock projection 8 for the circuit board 4 is provided on the bottom part.

Title: Plumb bob nd stabilizing base therefor
Inventor: YAMAMOTO NOBUYUKI
IPC: G01C15/10
Filed: 1993-06-14
Abstract: PURPOSE:To provide a plumb bob wherein time required for the plumb bob to stop swinging can be shortened. CONSTITUTION:An attaching device for a plumb bob is attached to a pillar 7, and a plumb bob thread 2 is passed through a hole on a plate-like body 5 so that a plumb bob 1 is attached to the tip of the thread to perform measurement. When an amplitude of swinging of the plumb bob 1 is larger than a diameter of the hole on the plate-like body 5, the plumb bob thread 2 moves while pulling the plate-like body 5 after it comes against a rim of the hole on the plate-like body 5. Frictional force between a lower face of the plate-like body 5 and an upper face of a base 4 provides a load for the plumb bob 1 with the body 5 moving, thereby attenuating swinging of the plumb bob 1. Therefore swinging of the plumb bob 1 can be rapidly attenuated. When the plumb bob 1 is in a state close to a steady state, the plumb bob thread 2 is located approximately at the center of the hole of the plate-like body 5, so that the plate-like body 5 does not influence the plumb bob thread 2.

Title: Erroneous connection detecting circuit for cable
Inventor: SHIMAUJI MASAHIRO
IPC: G01R31/02
Filed: 1987-07-03
Abstract: PURPOSE:To discolor a construction error at the time of manufacture at an early stage, by providing a predetermined voltage source to one of electronic circuit units to be connected to each other and providing a detection circuit to the other and detecting the voltage sent through a cable. CONSTITUTION:When multicore cables 8, 9 are correctly connected, both of two inputs (a), (b) of an EXNOR 4 are low potential and the output (c) thereof becomes high potential. Therefore, almost no current flows to a light emitting diode 6 and said diode puts out lights. If at least one of the multicore cables 8, 9 are unconnected or not correctly connected by erroneous connection, one input signal (a) of the EXNOR 4 becomes high potential of 5 volt and, therefore, the output (c) of the EXNOR 4 becomes low potential. Therefore, a current flows to the light emitting diode 6 and said diode 6 lights to inform that connection is not normal and, in a control circuit, it can be detected that cable connection is abnormal, because the output (c) of the EXNOR 4 is low potential.

IPC: G11C11/34
Filed: 1988-07-05
Abstract: PURPOSE:To reduce the average operating current of a substrate back bias voltage generating circuit by selectively causing the substrate back bias voltage generating circuit, whose operation is selectively stopped, to go to an operating condition according to the coupling of an activation control signal and specifying a period, during which the operation is stopped, as user specification. CONSTITUTION:In the prescribed coupling of the activation control signal, the operation of a built-in substrate back bias voltage generating circuit VBBG is selectively stopped and this circuit is caused to go to the operating condition according to the coupling of the activation control signal. Then, the period, during which the operation is stopped, is specified as the user specification. Accordingly, the operation of the built-in substrate back bias voltage generating circuit VBBG can be intentionally stopped in a range that a trouble is not generated in the operation of a dynamic type RAM. Thus, the average operating current of the substrate back bias voltage generating circuit can be reduced at a standby time.

Title: Cassette device for magnetic bubble memory
Inventor: KANEKO KEIICHI
IPC: G11C11/14
Filed: 1982-09-29
Abstract: PURPOSE:To make impossible unloading of a cassette during operation by driving a solenoid with a signal displaying the operation of a bubble memory so as to activate a lock mechanism and inhibiting the unloading of the bubble cassette. CONSTITUTION:A magnetic metallic piece 8 is fitted to a lock lever 3 at a position opposite to a solenoid 5, and when the solenoid 5 is not excited, the lever 3 is detached from a cassette 1 with a spring 6 and the lock is released. When a signal displaying that the bubble memory is in operation is applied to a base of a transistor 7, the solenoid 5 is excited and the metallic piece 8 is attracted into the solenoid 5. Thus, when the lever 3 is inserted to a groove 4 of the cassette 1, the cassette 1 is not unloaded from a holder 2. Thus, unloading due to misoperation is avoided and the destruction of memory information is prevented.
