Title: Pattern forming material
Inventor: ENDO MASATAKA
IPC: G03F7/039
Filed: 1987-02-12
Abstract: PURPOSE:To obtain an Si resist material having high sensitivity to KrF excimer laser light and high resolution by introducing oxygen atom into polysilane skeleton. CONSTITUTION:This pattern forming material consists of the compd. contg. the repeating unit expressed by the formula I. In the formula I, R1-R4 are substituents, of which at least one is a benzene ring or a sensitive group contg. benzene ring. The wavelength of the polysilane is moved to nearly 250nm and Si-Si bonds are easily cut by the KrF excimer laser when the oxygen atom is coordinated as shown by the formula I, by which the sensitivity is increased by about 100 times as compared to the conventional Si-contg. resist. Formation of the Si-contg. resist pattern as the upper layer of the two-layered resist at the time of exposing and developing by DUV light and excimer laser light in particular is thereby permitted with the high sensitivity and high resolution.

Title: Electronic switchgear
Inventor: TAKAGI MIKIO
IPC: H03K17/28
Filed: 1980-03-11
Abstract: PURPOSE:To make the on and off operation execute sharply even in case of the electric power source which has full-wave-rectified high frequency, by inserting a diode into at least one of the emitter circuit and the collector circuit of a transistor. CONSTITUTION:In the electronic switchgear S, a diode 4 is inserted into the emitter circuit of the Tr3 in order to stop a leakage current by the electrostatic capacity between the base and emitter on the transistor Tr3, which becomes a problem due to the fact that the AC power source 1 is high frequency. And now, when the AC power source 1 of high frequency is full-wave-rectified and connected to the switchgear S, a current flows into the base circuit of the Tr3 through the drain-source of the FET8, therefore the Tr3 becomes in conduction. After that, charging voltage of the electrolytic capacitor 9 instantaneously exceeds pitch-off voltage of the FET8, and the FET8 becomes off. After the Tr3 has turned off, a leakage current by the  electrostatic capacity between the base and emitter of the Tr3 is stopped by a  characteristic of rectification of the switching diode 4 having a speed which matches switching of the Tr3, and the switchgear S turns off sharply.

Title: Measurement of gas density using solid electrolyte
Inventor: USUI TOSHIO
IPC: G01N27/41
Filed: 1987-02-17
Abstract: PURPOSE:To measure the density of a gas accurately, by measuring a threshold current in an atmosphere of a low pressure with a threshold current type gas sensor so that a gas to a sensor element is diffused in a Knudsen's manner. CONSTITUTION:A solid electrolyte 1 of stabilized zirconia is provided with an anode 2 and a cathode 3 on both sides and is heated with a heater 6 up to several 100 deg.C. When a voltage is applied to both electrodes 2 and 3, oxygen in an atmosphere is turned with the cathode 3 to oxygen ions and transferred to the anode 2 through the solid electrolyte 1, causing a current to flow. The diffusion of oxygen flowing form a gas passage hole 5 of a gas diffusion control body 4 is controlled to be flat at an area where the applied voltage exists, developing a threshold current. here, the atmosphere gas is brought down to a low pressure to cause a Knudsen's diffusion. In the atmosphere of Knudsen's diffusion, the threshold current is linearly proportional to the concentration of oxygen. Thus, the knudsen's diffusion is caused under the atmosphere of a low pressure, thereby enabling highly accurate measurement of the density of a gas.
