Title: Method and apparatus for measurement of air flow rate
Inventor: SUGAYA ATSUSHI
IPC: G01F1/00
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which the pulsation of an air current can be measured without delay and precisely by a method wherein, on the basis of a flow-rate detection signal whose response delay is restored, a threshold value is detected and the direction of the flow of the air is estimated on the basis of the crossing of the threshold value with the flow-rate detection signal whose response delay is restored. SOLUTION: A microcomputer 40 compensates the response delay of a flow-rate detection signal which is obtained from a heat-ray probe 11 and which contains a response delay. It sets a threshold value on the basis of the maximum value and the minimum value of the detection signal whose response delay is compensated, and it judges a reverse-flow section. According to the judged reverse-flow section, the detection signal is compensated, and an air flow rate is measured precisely. That is to say, in order to reduce a measuring error at the pulsation of the air flow rate, the response delay of the flow-rate detection signal obtained from the heat-ray probe 11 is restored. A threshold value is computed on the basis of the detection signal whose response delay is restored.  The direction of the flow of the air is estimated on the basis of the crossing of the threshold value with the detection signal whose response delay id restored. Thereby, a following-flow section is discriminated from the reverse-flow section without delay. A correction processing operation can be performed, and the measuring accuracy of an average air flow rate can be increased when a reverse flow is generated.

Inventor: YOSHIOKA SHIRO
IPC: B65H3/00
Filed: 1993-04-08
Abstract: PURPOSE:To simplify separation of a lamination plate aluminum foil into plate aluminum foils in each unit number. CONSTITUTION:In a lamination plate aluminum foil A, a sheet 2 for separation, the both surfaces of which are smooth, and an insertion sheet 3 having a coarse surface 3b being a surface superposed with the thin sheet 2 for separation and a smooth surface brought into adhesion contact with the plate aluminum foil 1 side are located in a superposed state between the plate aluminum foils 1 and 1 in each unit number (a). When the lamination plate aluminum foil A is horizontally displaced as the aluminum foil is pressed, a slip is generated between the contact surfaces of the thin sheet 2 for separation having the low coefficient of friction and the insertion sheet 3. The lamination plate aluminum foil is displaced in a stair-form manner at every unit number (a) and the number of the plate aluminum foils 1 necessary to molding of an aluminum foil container is taken out.

Title: Sheet transfer state detecting device
Inventor: ISAKA KAZUO
IPC: B65H7/06
Filed: 1982-06-22
Abstract: PURPOSE:To stop the transportation of a sheet by detecting the transfer state of the sheet by a light emitting and photo detecting means disposed before and behind a heat chamber to generate a detecting signal. CONSTITUTION:When a sheet 2 is in a proper transfer state, the light emitted from light emitting means 3 advances as shown by an arrow 5 to be detected by a photo detecting means 4. In the case where there is any failure in sheet running and a part of the sheet 2 floats, the light emitted from the light emitting means 3 is intercepted by the sheet 2 as shown by an arrow 6 not to reach the photo detecting means 4, to detect that light does not arrive, then a detecting signal is immediately generated. A control portion 31 is adapted to stop transporting the sheet 2 and applying electricity to heaters 11, 12, 13 in response to the detected signal.

Title: Grinding work method
Inventor: HASHIMOTO MASAHIRO
IPC: B24B7/22
Filed: 1982-06-24
Abstract: PURPOSE:To grind fragile member efficiently and accurately, by contacting the fragile member with medium such as fluid or solid member having lower temperature then grinding the cracked portion on the surface caused through heat- shock. CONSTITUTION:In the relation between the strength and the temperature of fragile member, the rupture mechanism will develop from the fragility rupture region I to the quasi-ductility rupture region II and the ductility rupture region IIIand the strength will deteriorate sequentially as shown by the bent line 1. When holding the fragile member in the high temperature region where the strength will deteriorate and instantaneously contacting with medium having lower temperature, the differential temperature will cause heat-shock on the contact face to produce crack. In case of temperature controlled medium, the optimal heat-shock differential temperature will cause micro crack at the contacting portion thereby the fragile member can be grinded efficiently and accurately.

Abstract: PURPOSE:To reduce erosion in inner face of a vessel and to improve operational efficiency by arranging a main electrode above the center part in the molten steel vessel and sub-electrode arranged apart from the main electrode, reducing interval between the sub-electrode and molten steel and concentrating the power into the main electrode. CONSTITUTION:Arc 21 is generated from the main electrode 7 arranged above the center part of the molten steel vessel 2 to concentrate the power.
