Filed: 1988-08-24
Abstract: PURPOSE:To display the height of an echo waveform more accurately by dividing the addresses of waveform memories into address groups, and sequentially sending the data of the maximum values among the data stored in the respective addresses into display memories. CONSTITUTION:This device is composed of the following parts: a transmitting part 3 which outputs specified pulses to an ultrasonic wave probe 2; a receiving part 4, a liquid crystal display part 15; and a display memory 16m. When an echo from a body to be inspected 1 is received, the data are sampled at a specified period and sequentially stored in each address in a waveform memory 6. When the stored data are displayed on the display part 15, the addresses in the memory 6 are sequentially divided by specified number based on the number of the addresses in the display memory 16m and the measuring range of the echo waveforms. Thus the address groups are formed. The data of the maximum values are selected for every address group. The data of the maxi mum values of each address group are sequentially sent into the memory 16m. The display is performed on the display part 15 based on the transferred data.

Title: Temperature-depending pressure detection switch and liquid pressure control system using same pressure detection switch
Inventor: KOIKE ICHIRO
IPC: F15B1/02
Filed: 1989-08-11
Abstract: PURPOSE:To change switch change-over setting pressure in connection with a temperature change by changing spring force which sets up the switch change- over setting pressure related to the ON-OFF change-over working, in connection with a temperature change. CONSTITUTION:When pressure liquid introduced into a pressure liquid lead-in port 8 reaches prescribed pressure of the bigness to overcome the spring force of a gas spring 9, a piston 10 moves against the spring force to transfer a pusher 11 in the same direction. The transfer of this pusher turns a constantly closed switch part OFF. When the peripheral temperature rises, gas G of a closed container 9a expands in accordance with its rise so that the pressure inside the closed container 9a rises to increase the spring force of the gas spring 9 in accordance with temperature rise and as a result to increase also the switch change-over setting pressure of a pressure detection switch 7. Depending on peripheral temperature, switch change-over setting pressure, therefore, can be changed.

Title: Pattern formation
Inventor: AZUMA TSUKASA
IPC: G03F7/38
Filed: 1990-08-09
Abstract: PURPOSE:To obtain excellent resist patterns through reduction in deterioration in profile of resist cross section by changing temperature stepwise in the direction of resist film thickness during postexposure bake. CONSTITUTION:An Si substrate 20 is coated with a negative chemical amplification type resist 21 for KrF excimer laser exposure use with a thickness of 1mum and baked at 90 deg.C for a min before pattern exposure of 60mJ/cm<2> to prepare a specimen 22. After it is subjected to the prebake step for vaporizing the flux in the resist, the temperature of a hot plate 23 is set at l30 deg.C while air 24 cooled to 5 deg.C is flowed from above the specimen 22, and 1min postexposure bake is made with the Si substrate 20 mounted. This allows compensation of decreases in development speed generated by resist absorption accompanying the exposure shortage of a resist bottom. This can be confirmed by the fact that an ideal resist pattern 21a having a vertical and rectangular cross section can be obtained without resist residues upon a later 2min development with an alkali only developer.

Abstract: PURPOSE:To obtain the characteristics of excellent response and structure which is easily manufactured by directly attaching an electrode onto an active layer consisting of indium-gallium and arsenic phosphide grown on an indium phosphide substrate. CONSTITUTION:An N-InP layer 12 in thickness of approximately 10mum and an InGaAsP layer 13 in thickness of 1mum as a light-emitting layer are formed onto a P-InP substrate 1 in thickness of approximately 100mum in succession, a P contact 14 and an silicon dioxide film 15 in thickness of approximately 2-3mum are shaped as electrodes, and a gold plated layer 16 in thickness of 20mum is formed onto the surfaces of the contact 14 and the film 15.

Title: Composition for liquid junction part of reference electrode
Inventor: TSUTSUI SEIJI
IPC: G01N27/30
Filed: 1986-09-08
Abstract: PURPOSE:To obviate leakage of an internal liquid and to maintain the good liquid junction state with a liquid to be examined by forming a liquid junction part of a material prepd. by intimately mixing and solidifying a material which forms an insoluble compd. by combining with water and water soluble emulsion. CONSTITUTION:For example, calcined gypsum (CaSO4.1/2H2O) is intimately mixed with a water soluble vinyl acetate emulsion and the mixture is packed in the pores to serve as the liquid junction part of a reference electrode and is solidified. The calcined gypsum reacts with the water in the vinyl acetate emulsion and solidifies by forming gypsum (CaSO4.2H2O). The packing effect is improved when the gypsum is packed into the pores of the liquid junction part of the reference electrode by volumetric expansion of this time. On the other hand, the vinyl acetate molecules are polymerized to form macromolecules from the emulsion state as the moisture around the same is lost. Said molecules solidify by including the periphery of CaSO4.2H2O and are thereby packed and tightly adhered in the pores. Such small pores and gaps through which the internal liquid pass directly as in the conventional liquid junction part do not exist in the compsn. formed in the above-mentioned manner. The outflow and leakage of the internal liquid are, therefore, obviated.
