Title: Throughput reducing method for fault simulation
Inventor: KAMIWAKI MIKA
IPC: G06F11/26
Filed: 1991-01-31
Abstract: PURPOSE:To reduce the throughput of a fault simulation by recognizing an area wherein the influence of a fault can not be observed. CONSTITUTION:When one of the divided groups of an input pattern set is called as a pattern group, fixed value simulation which aims at the fixed value of an external input terminal is performed in a pattern group unit and an observable path is traced from the external output terminal to an input side in consideration of an observable path by using the simulation results to recognize the area 350 which can not be observed, thereby excluding the fault in the area from the objects of the process of the fault simulation. Further, a fault on a fixed line signal line is propagated as much as possible by previous fault propagation. The number of process object faults of the fault simulation is decreased and the propagation range of the faults is reduced so the throughput of the fault simulation is reduced.

Abstract: PURPOSE:To improve the A/D conversion accuracy even when electronic components with a bad temperature characteristic are employed for a signal processing section by allowing a correction section to recognize an output change in response to temperature of the signal processing section thereby applying correction to an A/D conversion output according to the result. CONSTITUTION:A signal processing section 1 fetches an analog input and applies properly signal processing and its output is A/D-converted by an A/D converter section 2. A switch section 6 selects an analog input or a reference voltage from a reference voltage generating section 5 and inputs the selected signal to the processing section 1. A switching section 7 selectively inputs the output of the processing section 1 and the reference voltage to the A/D converter section 2. Through the constitution above, a control section 3 applies switching control to both the switch sections 6, 7 to obtain an A/D conversion output of the reference voltage through the processing section 1 and an A/D conversion output not through the processing section 1. Thus, the processing obtaining an output change depending on the temperature of the processing section 1 is periodically implemented from each output and the output of the A/D converter section 2 is corrected by using the result, then the A/D conversion accuracy is not deteriorated.

Title: Conveying device
Inventor: AOKI TAKANOBU
IPC: B65G17/38
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To prevent a chain guide from being worn, so as to smoothen conveyance, by forming a roller of a conveyance chain by a first roller to be engaged with a sprocket and a second roller to be brought in contact with the chain guide. SOLUTION: In a paper discharging chain 7, a first roller 751 and a second roller 752 are held and guided by upper and lower chain guides 8, 8, and a specified conveying passage is formed. Since large force is applied to the roller 751 to be engaged with the teeth of a driving side sprocket 4 at this time, the roller 751 can not be rotated. However, since the roller 752 to be brought in contact with the peripheral part 8a of the chain guide 8 has a structure independent of the roller 751, the roller 752 keeps the rotatable state. Accordingly, since the roller 752 to be brought in contact with the peripheral part 8a of the chain guide 8 guides the peripheral part 8a while being rotated, generation of surface abrasion of the peripheral part 8a and noise can be prevented.

Title: Fluid tank
Inventor: TETORI SOTOSHIRO
IPC: B05C19/02
Filed: 1987-01-22
Abstract: PURPOSE:To make it possible to satisfactorily and smoothly carry out a coating process by jetting air from an auxiliary air feed pipe, corresponding to the sediment part of a granular material which is produced in a tank under the action of air feed from an air feed chamber through a filter, so that the granular material is uniformly floated. CONSTITUTION:In a tank section 3, there are provided small pipe-like auxiliary air feed pipes 7 which are arranged being curved or crossed with a predetermined extent in a horizontal cross-section of the inside of the tank section 3. Further, air feed holes 9 are formed in the peripheral wall of each auxiliary air feed pipe 7 so that compressed air is fed from the air feed holes 9 into the tank section 3. Therefore, even though a sediment section of a granular material is formed due to compressed air blowing up from an air feed chamber 4 through a filter 2, since compressed air is fed from the air feed holes 9 in the auxiliary feed pipes 7, the sediment section falls into a floating condition. Thus, the granular material is uniformly floated, thereby it is possible to carry out a satisfactory and smooth coating process.

Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To prevent dew condensation from being caused on an inner pan inner surface because of the shortage of heat insulating effect or the presence of a non-heating part by forming the clearance between a cover member and the inner pan so as to be partially narrowed to provide a part having high heat retaining effect. SOLUTION: An inner pan 1 has a pair of handles 2, and a jar body 3 has a recessed part 4 for receiving the handle 2 on the upper part. The inner wall 12 of the recessed part 4 is raised to a fixed height, an inward support surface 13 having a prescribed width is formed on the upper end thereof, and a cylindrical cover member 5 is set on a protecting frame 14 under the support surface 13. The curvature radius in the part of the recessed part 4 is set larger than the other part to make the clearance (g') between the inner pan 1 and the cover member 5 in the range of A of the recessed part 4 smaller than the clearance (g) in the other part.  Thus, a warming heater 6 installed to the circumferential surface of the cover member 5 is made close to the inner pan 1 in the part of the range A to improve the heat insulating effect, and dew condensation is prevented from being caused on the inner surface of the inner pan 1.

IPC: H01L27/10
Filed: 1986-01-24
Abstract: PURPOSE:To shorten the access time and to prevent a wrong selecting action by maintaining a larger current for an upper word line in a transient period during which the voltage of the upper word line is equal to the non-selection voltage than the current of a non-selection mode and therefore securing high- speed rise of a holding current line and a word line of a memory circuit. CONSTITUTION:The levels VX of selected word lines 110 and 111 of a memory cell 100 are changed to a high level VXH from a low level VXL and then to the non-selection (VXL) from the selection (VXH). These switches are detected by a circuit 101. Then a circuit 102 delays properly the detection signal or increases the pulse width. At the same time, the detection signal is changed to a proper level and sent to a current switch circuit 103. The output of the circuit 102 is held at an output level until the line 110 is fixed completely at a holding level. Then the circuit 103 flows a current continuously for a period during which the level VX is fixed at a sufficiently low level from an instant that it is changed to the non-selection form the selection.

Title: Etching method for semiconductor crystal
Inventor: ITO KAZUHIRO
IPC: H01L21/3063
Filed: 1986-01-24
Abstract: PURPOSE:To enable the introduction of a method of conducting the identification of a P-N junction and the processing of crystals, by forming a step between P-type and N-type regions or in a boundary portion between the two regions when the crystals having the P-N junction are etched. CONSTITUTION:Semiconductor crystals 1 are composed of an N-type region 2 and a P-type region 3. An electrode 4 for impression of voltage is formed in a part of the surface of the P-type region 3. After a lead wire 5 is fitted to the electrode 4, insulative wax or the like is connected. Voltages being plus and minus to each other are impressed between the lead wire 5 and another electrode dipped in an etching liquid, and the semiconductor crystals 1 are made to contact with the etching liquid. While an etching speed increases at voltages -2V or below, +1V and +12V or above with respect to P-type crystals and at a voltage -2V or below with respect to N-type crystals, it is held at a substantially prescribed value in other conditions. In the vicinity of +1V, in particular, a step is formed in a portion of P-N junction due to overwhelmingly rapid etching of a P-type portion. Although a relative etching speed decreases at voltages of +5-+10V, only an interface of P-N junction is etched rapidly, and consequently a groove-shaped step is formed.
