Title: Beam torsion type balance
Inventor: TAKAOKA KOUICHIROU
IPC: G01G1/18
Filed: 1980-10-21
Abstract: PURPOSE:To decrease residual strains considerably and to make the execution of microweighing of high accuracy possible by constituting the torsion part of a beam torsion type balance of an amorphous alloy material. CONSTITUTION:A torsion part of a balance of a beam torsion type is constituted of an amorphous alloy material. For example, a torsion part 1 is made by melting an iron-nickel alloy at 1,600 deg.C, spraying the same onto a high speed revolving drum cooled to 25 deg.C or rolling mill, and forming the same into a thin film of an amorphous alloy by a liquid quenching method, then cutting the same into a rectangular strip shape and forming said part. This is combined with a beam 2, a weight pan 3, a sample receiving pan 4, a centroid adjusting weight 6, etc., and is fixed by torsion fixing fittings 7. Weighing is carried out by using a device 8 for reading beam angle change. As compared to the case of conventional titanium material torsion, residual strains decrease to about 1/10 and the weighing of high accuracy is made possible.

Title: Infrared-ray combusting apparatus
Inventor: KOMORI MINORU
IPC: F23D14/14
Filed: 1979-11-15
Abstract: PURPOSE: To lower the combusting noise of an infrared-ray combusting apparatus using a gas fuel and to obtain uniform intensity of combustion, by designing a flame board made of a heat-resisting porous plate such that round flame holes having a large diameter and those having a small diameter are formed alternately at the lower portion of the flame board.  
     CONSTITUTION: Gas fuel supplied from a gas supply pipe 3 is injected into an inner space formed inside a flame board 1 from a gas injecting port 4 and ignited by an igniting means (not shown). On the other hand, air necessary for combustion is supplied from round holes 2aW2c formed in the flame board 1. Therefore, flame is formed just at the positions of these flame holes 2aW2c. At the same time, flame board 1 is red-heated and infrared rays are radiated through a heat transmitting member 6 attached to an outer case 5 which is placed with proper spacing from flame board 1. Here, arrangement is such that round flame holes 2b having a large diameter and those 2c having a small diameter are disposed alternately at the lower portion of flame board 1, so as to prevent excessive supply of air and to render the intensity of combustion uniform over the entire surface of the flame board.

Filed: 1984-07-16
Abstract: PURPOSE:To reduce the load capacity of a bit line, to speed up reading and to decrease the transient current of the bit line by providing a transfer gate intermitting the bit line in synchronizing with a sensor amplifier control signal. CONSTITUTION:When precharging is completed and a word line X rises in the condition where a bit line B, antis B and B' and the anti B' come to a power source potential VDD, a potential difference in accordance with data contents of a memory cell appears on the bit line. When a sensor amplifier control signal phis goes to ''H'', the potential difference is amplified by a sensor amplifier consisting of P type transistors P4 and P5, N type transistor N1 and N2, etc. In the midist of the amplification, a signal phiSB synchronous with the signal phis goes to ''H'' to turn off transfer gates T1 of P type transistors P00 and P01, N type transistors N00 and N01, etc.; and the bit line B, and its anti B' are separated. Thus the load capacity of the sensor amplifier is reduced, and data is read out a high speed. Simultaneously, a transient current applied to the transistor of the sensor amplifier can be reduced.

Abstract: PURPOSE:To provide a method for automatically filling a bathtub with hot water through which a problem arising when a circulation decision method and an inflection point method are properly used, especially the occurrence of splash of drop-in water and the generation of noise during transfer to the inflection point detection method are reduced. CONSTITUTION:Two-way conveyance of hot water to a bathtub 10 by using an additional burning circulation circuit 20 and it is decided whether a drop-in flow rate per unit time exceeds a specified value. When it exceeds the specified value, transfer to an inflection point detection mode in which the inflection point of an output value from a bathtub water level sensor 52 is captured through one-way conveyance is performed. When it is below a specific value, transfer to a circulation decision mode through two-way conveyance is executed to regulate a bathtub water level to a level higher than that of a circulation fitment 11 of the bathtub. In this case, a current bathtub water level is set to a reference water level and drop-in is carried out until the set water level is detected, and this way provide a method for automatically filling a bathtub with hot water. When transfer to the inflection point detection mode is effected, after a drop-in flow rate through two-way conveyance is decreased to a value lower than a specified flow rate, it is switched to one-way conveyance.
