Title: Selecting method for ge light-receiving element
Inventor: SUDO HIROKI
IPC: H01L21/66
Filed: 1985-04-23
Abstract: PURPOSE:To select an acceptable or defective Ge light-receiving element easily by controlling the Ge light-receiving element for a fixed time at the high temperature of a temperature within a predetermined range and obtaining the dark current value of the Ge light-receiving element. CONSTITUTION:When there are populations consisting of a plurality of Ge light-receiving elements, samples are sampled through samplings from each population, and a storage test is conducted in a prescribed short time within the temperature range of 250-300 deg.C at a temperature higher than a normal high-temperature bias test regarding several sample. Reverse voltage-current characteristics are measured before and after the test, and the Ge light-receiving elements, the changes of dark currents thereof are kept within a tolerance, are regarded as acceptables and populations, in which the number of defective Ge light-receiving elements is larger than stipulations, as defectives. When the number of acceptable Ge light-receiving elements is larger than stipulations, the normal high-temperature bias test is further conducted regarding acceptable Ge light-receiving elements, and populations in which the number of final acceptable Ge light-receiving elements is larger than stipulations are acquired.

IPC: C07F7/18
Filed: 1992-03-09
Abstract: PURPOSE:To selectively and readily produce a cis-olefin useful as an intermediate for various fine chemicals under a mild reaction condition in a high yield by reducing an alkine with formic acid in the presence of a palladium catalyst. CONSTITUTION:An alkine (e.g. 2-undecyne) of formula I [R1, R2 are H, ester, substituted silyl, carboxyl, cyano, (substituted)1-20C aliphatic hydrocarbon, (substituted)phenyl] is reduced with formic acid in the presence of a palladium catalyst to give a cis-olefin of formula II (e.g. 2-undedecene).

Title: Sensor for detecting material in liquid by leak surface acoustic wave in which linbo3 is used as piezo-electric substrate
Inventor: MORIIZUMI TOYOE
IPC: H03H9/25
Filed: 1987-04-08
Abstract: PURPOSE:To obtain a sensor for detecting the material in liquid having good detection accuracy by using LiNbO3 having a cut plane, the normal of which is the axis rotated by 5 deg.-85 deg. around the X-axis from the Y-axis of the crystal axes as a piezo-electric substrate. CONSTITUTION:The piezo-electric substrate 10 is the rotated Y plate of the LiNbO3 cut within the range of 5 deg.-85 deg. angle of rotation. An input signal generated by an oscillator 15 is converted to leak surface acoustic waves in the substrate 10 by comb- shaped electrodes 111, 112 for input. These waves propagate in the substrate 10 and a receptor 3 and are converted to an electric signal by comb-shaped electrodes 121, 122 for output. The output signal is compared with the input signal generated in the oscillator 15 by a phase comparator 16. The phase difference between these two signals is the propagation delay time of the leak surface acoustic waves between the electrodes 111, 112 and the electrodes 121, 122. The propagation speed of the leak surface acoustic waves changes when the specific material in the liquid 7 to be detected is adsorbed on the receptor 3. The change quantity of the phase is thus measured by the phase comparator 16, by which the detection of the specific material is permitted.

IPC: F16K31/10
Filed: 1986-04-15
Abstract: PURPOSE:To aim at miniaturization in a proportional valve, by making a meson retract from a position, where a tip of a valve lever is engaged with a cam surface, because of interruption of current-energization to a solenoid, losing its pressing force to the tip of the valve lever and thereby closing a valve port.

When the continuous rating current is interrupted, the meson 40 is moved to a skirt part of an engaging surface 14a, retracting from the lower part of a cam surface, whereby the valve body 8 goes up and the valve port 6 is closed. Therefore, it comes to unnecessary to separately set up an on-off valve for checking a flow of fluid in preparations for the time of power failure, thus a device is miniaturized.
