Title: Apparatus for generation of sinusoidal output signal
Inventor: SAFUDAA EMU ASHIYAA
IPC: H03B5/20
Filed: 1992-10-22
Abstract: PURPOSE: To provide a device that generates an output signal, in response to an input signal of a variable input level through a digital signal processing technology, without causing destructive noises between frequency transitions. CONSTITUTION: An input signal enters a delay circuit 16 from a terminal 18, is delayed in the circuit 16 for a one clock period, and the delayed signal is outputted from a terminal 20. The output is divided into two, the one is given to a delay circuit 24, where the signal is further delayed by one clock period and the delayed signal is fed to an adder 38 of a next stage. The other output from the delay circuit 16 enters a multiplier 28, where a multiplier δis multiplied with the signal, and the resulting output is fed to the adder 38. The adder 38 adds the two inputs and provides an output of a sum from a terminal 42 as a sine signal X(n). Part of this output is fed back to the input terminal 18 of the delay circuit 16 through a feedback line 44.

IPC: G05B15/02
Filed: 1989-10-31
Abstract: PURPOSE:To quickly and accurately grasp the reduction of the parts cost by applying an EDP system to process the total necessary number of each parts calculated for each device and the scheduled production amount. CONSTITUTION:A punched parameter 1 includes the parts having its cost to be reduced, the costs calculated before and after improvement, and a retrieving period. Then the parameter 1 is inputted via a reading device 2. A CPU 3 uses the subject parts as a key to retrieve a parts constitution information file 4 for extraction of the codes (highest levels) and the necessary number of parts for all devices that use the subject parts. Then the CPU 3 extracts the scheduled production amounts of these devices within the retrieving period out of a production schedule information file 5 and calculates the cost reduction amount. Based on this calculation result, a total list 7 (incl. a production schedule information list and a parts necessary number list) is outputted from a printer 6. Thus it is possible to obtain a calculation system where the cost reduction is quickly and accurately grasped.

Title: Inspection method for inorganic separation film
Inventor: KATO MASAKI
IPC: G01B11/30
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To obtain an inspection method in which a film formation state is judged by a nondestructive optical inspection capable of being used after the inspection and in which the existence of a defect in an inorganic separation film can be inspected by a method wherein a porous support is impregnated with an impregnating substance having a specific refractive index so as to be made transparent. SOLUTION: A porous support is impregnated with an impregnating substance having a specific refractive index, only the porous support is made transparent, and whether a defect exists in an inorganic separation film or not can be judged. For example, in the shape of a laminated body in which a zeolite film (an inorganic separation film) is laminated on an alumina support, the zeolite film is carried by the support. Since both the zeolite film and the alumina support are white, the laminated body becomes white as a whole, and a defect cannot be detected. Then, when the laminated body is impregnated with diiodomethane, only the alumina support becomes transparent, and the part of the zeolite film can be observed. When the surface of the zeolite film is observed, it is not changed from a state before the laminated body is impregnated as long as no defect exists.  When a crack exists, a stripe-shaped crack can be confirmed.

Abstract: PURPOSE:To provide a durable and reliable diaphragm valve structure by forming at least two projecting parts between the in-flow passage and the out- flow passage. CONSTITUTION:When the compressed air is fed to an air-feeding port, the pressing force is applied to a diaphragm 14 to press it down, the space between a valve seat 12 and an opening part of a seat holder 13 is reduced in volume, and abutted on the upper part of the valve seat 12 at contact points t1-t2 to seal the opening part. When the pressing force is further applied to the diaphragm 14, the projecting part of the valve seat 12 is compressed, and also abutted on the projecting part of the seat holder 13 at the other point t3. The diaphragm 14 abutted on the valve seat 12 and the projecting part of the seat holder 13 keeps the in-flow passage 21 in the air-tight condition at the valve seat 12 and the seat holder 13 respectively.

Title: Manufacture of nb-ti multiple core superconducting wire
Inventor: SUZUKI HIDEMOTO
IPC: H01B12/10
Filed: 1989-10-31
Abstract: PURPOSE:To increase a critical current density in a low magnetic field by giving a heat treatment and a cold working alternately twice under fixed conditions. CONSTITUTION:A compound wire is given a heat treatment at 390-410 deg.C for 1-10 hours and then a cold working at 89-93% area reduction ratio. The wire is given a further heat treatment at 360-380 deg.C for 60-100 hours and then a cold wire drawing process at 89-93% area reduction ratio. Outside the above ranges of heat treatment and area reduction ratio, the critical current density of the wire in a low-intensity magnetic field cannot exceed about 6400A/mm<2>. As the wire easily disconnects if the heat treatment temperature exceeds 410 deg.C and 380 deg.C at the first stage and the second stage respectively, easy disconnection is prevented by the above treatment.
