Title: Method for detecting defective press-fitting of o-ring
Inventor: TOMITA KOJI
IPC: F02M55/02
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting defective press-fitting of an O-ring wherein a defective press-fitting of an O-ring such as obliquely fitted O-ring which is a male member is detected with sure when a male member such as a fuel jetting valve is engaged with a female member such as a fuel supply pipe. SOLUTION: By allowing a press-fitting jig 21 to which a fuel jetting valve 11 is fixed to approach a fuel supply pipe 12, a male protruding part 13 of the fuel jetting valve 11 is inserted into a hole 12a of the fuel supply pipe 12. Then, by allowing the press-fitting jig 21 to recede from the fuel supply pipe 12, the male protruding part 13 is pulled out of the hole 12a, when the pull-out load is detected by a load detector 23. Based on the fact that the pull-out load detected by the load detector 23 is smaller than a specified judgement value, such defective press-fitting of an O-ring 16 as the O-ring 16 is obliquely attached to the male protruding part 13 is detected.

Title: Two-dimensional image pickup device
Inventor: UEDA TAKAMI
IPC: H02P25/034
Filed: 1987-05-29
Abstract: PURPOSE:To miniaturize the whole of a device and to reduce a cost by using a voice coil type linear motor as the driving source which scans a one- dimensional image pickup element in a transverse direction. CONSTITUTION:Voice coil type linear motors are arranged on both sides of an element moving carriage 3 on which the one-dimensional image pickup element facing an optical element is mounted. When a current flows from a controller 41 to the voice coils 27 of the element moving carriage 3 in magnetic fields of permanent magnets 29, the driving force to drive the element moving carriage 3 in the direction of an arrow A (or an arrow B) is generated in voice coils 27, and the element moving carriage 3 is moved in the direction of the arrow A (or the arrow B) by this driving force to scan the one-dimensional image pickup element 25 in the transverse direction. Thus, the whole of the device is miniaturized to reduce the cost.

Title: Manufacture of semiconductor device
Inventor: KAWAGOE HIROHITO
IPC: H01L29/78
Filed: 1981-08-31
Abstract: PURPOSE:To realize a high speed, high integration MOSIC by a method wherein an oxidation resistant mask is placed on a substrate covered with a high concentration reverse conductivity type layer which is selectively oxidated to separate reverse conductivity type regions and the gate structure is built by removing channel region oxidated layer. CONSTITUTION:For example, an n type substrate 1 is overally diffused with a p<+> layer 2 and, for example, a nitride mask 3 is formed on FET source and drain regions and, if necessary, on a tunnel accommodated wiring region 7. Next, after forming an oxide layer 4 at a depth establishing some distance from the p<+> layer, and the part of the oxide layer 4 between source and drain regions 2a and 2b is selectively removed with help of a resist mask 9, for example, to form a depression 5. Next, a gate film 6 is formed on the depression 5 and, after providing contact holes in the nitride mask 3, an Al electrode for example is formed, completing an IC. By this, a high concentration structure can be formed on self-alignment manner and a high speed operation is ensured because gate parasitic capacitance can be reduced to the order of the p<+> layer 2 thickness and overlapping.

Filed: 1993-06-07
Abstract: PURPOSE:To prevent the vertical movement of a pinion and also to prevent wear by pinch by providing the pinion on the first linear guide side while angular moment acts duplicatively, a traveling frame tilts with a first linear guide as a fulcrum and the second linear guide side sinks. CONSTITUTION:The angular moment around a Y axis is acted on the traveling frame 30 so that the elevating and lowering arm 32 side falls with the first linear guide 30c1 close to the traveling frame as a fulcrum. This angular moment is received by the second linear guide 30c2 separated in the X-axis direction which is the separating direction of the elevating and lowering arm for the traveling frame 30 and the traveling frame is moved in the X-axis direction at the stable position. Since the pinion 30e is provided at the position in the same X-axis direction as the first linear guide 30c1 which is made to a tilting fulcrum, the pinion does not move vertically and wear by pinch between the pinion and a rack is also not generated. Consequently, positioning accuracy can be maintained satisfactorily extending over a long period of time.

In a thermostatic chamber 16, hot air is circulated by a blower, while hot water having a prescribed temperature is sent to a heater by a hot-water circulating unit, and the sheet, i.e. the reaction vessels, is transferred along the grooves each having a shape analogous to those of the reaction vessels. Therefore, the mixed reactive solution of a sample and a reagent is kept smoothly at a prescribed temperature and thus the reaction is accelerated.
