Abstract: PROBLEM TO BE SOLVED: To enable the highly accurate measurement of multiple component of force acting on equipment in environments in liquid and under the action of high pressure such as in deep sea by forming a pressure balancing chamber between two flanges connected with each other by a plurality of beams with strain gages. SOLUTION: A detector 20 for multiple component of force comprises a measuring side flange 1 and a fixed-side flange 2, and the flanges 1 and 2 are connected with each other by a plurality of beams 4 to 6. Then a strain gage is attached to each of the beams 4 to 6, and a pressure balancing chamber is formed between the two flanges 1 and 2 by fluid-tightly joining a bellows attached to the one flange 1 and a bellows diaphragm attached to the other flange 2. By this, as the bellows and the bellows-diaphragm fluctuate to equalize the pressure of the inside and outside of a detector 20, the need for pressure- prooving the container of the detector 20 is eliminated. Therefore, as detection performance is improved, highly accurate detection under high pressure is possible as in the case under atmospheric pressure. In addition, it is desirable. to arrange a solid cushioning in the pressure balancing chamber.

Title: Automatic weighing and labelling machine
Inventor: NISHIDA MANABU
IPC: G01G23/42
Filed: 1983-09-09
Abstract: PURPOSE:To correct automatically a zero point without stopping a device by monitoring a weight at a prescribed period, regarding its weight as a zero point when this weight becomes stable in some range, and correcting automatically the zero point. CONSTITUTION:In case a titled machine is set to a packing weighing pricing mode, a weight which is less than the minimum weight for issuing a label is measured on a weighing conveyor, and also in case it is stable, its weight is regarded as a zero point without depressing a zero point key, and it is corrected automatically. That is to say, a mode check is executed in a system controller side, and in case of the packing weighing pricing mode, a forced zero signal for executing an auto zero processing is outputted. The forced zero signal is outputted once per second. In a scale printer 40, this forced zero signal is checked, and at the time of ON, whether the weight is less than the minimum weight or not is checked in order to execute the auto zero processing, and in case of OK, a forced zero key processing is executed. In this way, the zero point can be corrected automatically without stopping a device.

Title: Bonding method for semiconductor substrate
Inventor: SATO HIROSHI
IPC: B24B37/04
Filed: 1987-07-02
Abstract: PURPOSE:To push out bubbles from bonding material when bubbles mix in the bonding material, and prevent effectively bubbles from mixing in the bonding material, by pressing a region on a semiconductor substrate along one direction, against a retaining base, in order, via the bonding material. CONSTITUTION:Pressing is performed by applying only a shaft-center cylinder 26, and then pressing is performed in order by applying outer-peripheral cylinders 27-29. Elastic bodies 26a-29a have the form of a part of a sphere or the form of a part of a cone. In addition, the concentric circular ring parts of a semiconductor substrate 11 are pressed in order against a retaining base 12. Therefore, if bubbles are included in bonding material 13, these bubbles are pushed out in the form of concentric circles toward the outer periphery of the semiconductor substrate 11, and after all, the bubbles are discharged from the bonding material 13. While the pressing force of the cylinder 26 or the like applied to the initial pressing is kept, the pressing applying outer- peripheral cylinders 27-29, etc., is performed in order. Therefore the bubbles once discharged do not permeate again into the bonding material 13.

Title: Carbonaceous friction material and its manufacture
Inventor: KOMATSU YASUKADO
IPC: C04B35/52
Filed: 1986-07-15
Abstract: PURPOSE:To get carbonaceous frictional material that is superior in anti- oxidization and exhibits desirable character without lowering its friction character by forming refractory phosphate in empty voids in carbon material, after impregnating it with phosphate solution and applying heat treatment thereto over 500 deg.C in a non-oxidizing atmosphere. CONSTITUTION:Carbon material is impregnated with phosphate solution for applying heat treatment thereto over 500 deg.C to form refractory phosphate in empty voids in carbon material. Then, by forming a refractory phosphate layer on the surface of the carbon material, its friction coefficient is increased. The reason is because the same function as friction adjusting agent is supposed to be provided, especially friction coefficient is increased under low load at low speed with low face pressure. And its oxidizing consumption is remarkably little, generated free phosphoric acid and the like is very little under high temperature due to friciton heat, and stable friction character is displayed. By giving anti-oxidization in such manner, it is possible to gain carbonaceous frictional material that has excellent characteristic under severe conditions.
