Title: Device for identifying wafer
Inventor: YABE SUMIO
IPC: H01L21/02
Filed: 1985-03-30
Abstract: PURPOSE:To realize high-speed identification of wafer, by mounting resonators and a loop coil by corresponding to wafers, and composing an antenna which transmits a sweep frequency wave to it and a detecting part which separates an information signal from a reflected wave. CONSTITUTION:A sweep wave on a medium band, which is generated in a sweep oscillator 310, is amplified in an amplifier 320, reaching a transmitting antenna 210. When an ID card 100 comes close to the transmitting antenna 210, ceramic resonators, with the sweep wave taken by a loop coil nearly becoming the resonance frequency wave, enter a resonant state, reflecting energy at the peak of the resonant state at the resonant frequency, and a reflected wave is reflected at the loop coil. This reflected wave is detected by a receiving antenna 220, however, its amount being extremely slight. Hence, use of a ringing detection method causes the ceramic resonators to successively resonate to generate a ringing, and the ringing signal is synchronized and detected by a detector 250 so as to take effective information at an amplifying-shaping device 330 in which a matched filter is used.

Title: Additive for measuring blood sugar value
Inventor: IWASE NORIMASA
IPC: G01N33/66
Filed: 1982-04-21
Abstract: PURPOSE:To reduce the hemolysis and decomposition during the preservation by adding a specified amount per 1ml of full blood of NaF, MgCl2 and NaH2PO4 and a required amount of anti-blood coagulation agent necessary for prevention of clot to blood. CONSTITUTION:0.5-2.0mg per 1ml of full blood of NaF, 0.01-0.20mg of MgCl2 and 0.05- 0.5mg of NaH2PO4 and a required amount of an anti-blood coagulation agent such as heparin salt for preventing clot are added to blood. When the quantity of NaF is below 0.5mg among additives combined, the sugar decomposition checking effect lacks and when it is above 2.0mg, a hemolysis is shown. The addition of MgCl2 provides a hemolysis preventing effect and a sugar deconposition checking effect unexpectedly. When the quantity thereof is below 0.01mg, the sugar decomposition checking effect and the hemolysis preventing effect lower previously because the sugar decomposition checking effect is not sufficient while when it is above 0.20mg, hard to dissolve sediment MgF2 is generated by reaction with NaF. Secondly, when NaH2PO4 is below 0.05mg, the sufficient hemolysis preventing effect cannot be obtained while when it is above 0.5mg, a slight hemolysis effect is shown. A secular comparison test for hemolytic property of the additives in this invention was done to compare with the conventional NaF additive commonly used with heparin salt and the concentration of plasma hemoglobin is 42 with the additive according to this invention when the blood is left alone for 24hr after the addition thereto, while it is 180 with the conventional NaF additive.

Abstract: PURPOSE:To maintain an air/fuel ratio constant irrespective of variation in the temperature of intake-air, by forming at least a part of a venturi with the use of a bimetal which deforms for increasing the cross-sectional area of the venturi in association with the temperature rise. CONSTITUTION:In a carburettor barrel 1 there are formed two chambers 4, 4 opposing together, having a length extending over the substantially entire length of a venturi 3, on both sides of the latter, with a stationary venturi part 5 being formed between the chambers 4, 4. Further, there is arranged a bimetal 6 having the same shape as that of the outer surface of the stationary venturi part 5, which is closely fitted in each chamber 4. Each bimetal 6 has its lower end 6a secured to an intake-air passage 2 and its upper end 6b extending outward and curved so that the upper end 6b projects into the chamber 4. With this arrangement, the bimetal 6 is in the condition shown in the drawings when the intake air temperature is below a predetermined temperature, but the upper end 6b of the bimetal 6 is curved when the temperature is above the predetermined temperature, so that the upper end 6b deeply enters the chamber 4, thereby the cross-sectional area of the venturi may be increased.

Title: Gas laser oscillator
Inventor: SUMINO TSUTOMU
IPC: H01S3/0971
Filed: 1988-03-23
Abstract: PURPOSE:To make it possible to oscillate a highly repetitive pulse laser in a simple structure and in a stable state, by preventing discharge gases from extending to adjacent split electrodes by using shield plates. CONSTITUTION:Each two split electrodes (a1, a2...an), which are not adjoining, are connected to a common discharge circuit and a trigger signal is supplied to each discharge circuit in serial order, staggering the timing. Therefore, a product material generated by a main discharge does not extend to a split electrode which stands by for the next main discharge. It much less happens that the product material generated by discharge extend to the other split electrodes a1, a2...an, since there are shield plates s1, s2...sn-1 between each split electrode (a1, a2...an). This method allows to oscillate a highly repetitive pulse layer in a simple structure and in a stable state.

Abstract: PURPOSE:To record a disconnection phenomenon of an electric power system and a phenomenon of a load variation, etc., by inputting an element of a time difference to a device for applying a trigger signal to a waveform recording device for recording a waveform before and after the trigger. CONSTITUTION:An input signal W is averaged through a full-wave rectifying circuit 4 and an averaging circuit 5, and becomes an output (c). In an A/D converter 6, the output (c) is digitized at every sampling time, is sent out as a data D to a memory 7, and is stored in order. Subsequently, in a comparator 8, a data Dd having a time lag, which has been stored already in the memory 7 is compared with the latest data D which is a converted output of the A/D converter 6, and when its difference exceeds some set level, a trigger generator 3 is driven, and a tirgger signal is generated. In this way, the trigger signal is generated only in a variation point in the input signal W by comparing a data train digitized one after another with a data train having some time lag.
