IPC: H01L21/762
Filed: 1981-09-30
Abstract: PURPOSE:To obtain a semiconductor device having an oxidized film isolating layer capable of being highly integrated without pattern conversion error due to bird beak by suppressing the production of a crystal defect by a method of burying the uneven surface between the surfce of a silicon substrate and an oxidized film formed partly in the groove with an oxidized material. CONSTITUTION:With a remaining pattern 110 as a mask a silicon nitrided film 107 in a groove 15 is etched, thereby simply and accurately forming an extremely thin remaining silicon nitrided film 107' on the side wall in the groove 105. Even if the groove 105 is tapered, the film 107' can be accurately formed on the side surface of the groove 105 by increasing the thickness of the remaining pattern formed on the side wall of the groove 105. In this manner, when a thick  oxidized film 112 to bury most of the groove 105 is formed by thermal oxidation, the production of a crystal defect due to thermal distortion to the substrate  101 can be remarkably suppressed around the film 112.

Title: Sealing member for rotary heat storage type heat exchanger
Inventor: MATSUDAIRA NOBUYASU
IPC: F16J15/52
Filed: 1994-06-14
Abstract: PURPOSE:To prevent the damage to a core and a sealing member due to its excess surface pressure by composing the sectional shape of a shoe by forming a thinner lightened part than both the thick ends of the shoe between both the ends. CONSTITUTION:The shoe 21 of a sealing member for constituting an inner seal 2 and an outer seal 3 is formed with a lightened part 21a made of a heat-resisting stainless steel and formed in a predetermined thickness (t) at its central part thereby to be formed in a shape having flexibility by reducing the rigidity of the central part. Since the pressure of high-pressure air from a high-pressure passage is operated at the part 21a in a direction for cancelling the thermal deformation of the shoe 21 occurring due to the fact that the member becomes high temperature at the time of operating a rotary heat storage type heat exchanger, the deformation of the shoe 21 is uniformized. Accordingly, the occurrence of a local surface pressure increase between both the ends of the shoe and the core is prevented, and the end faces of the shoe and the core are always brought into slidable contact with each other under uniform surface pressure, and hence the damage of the core due to the surface excess pressure increase is prevented.

Title: Moisture detector
Inventor: YANAGISAWA MICHIO
IPC: G01N27/12
Filed: 1988-06-23
Abstract: PURPOSE:To enable highly accurate measurement over a long period of time at a high temperature and a high moisture and in a wide range of temperature while preventing DC deterioration in a moisture sensor by providing a switching circuit to switch a direction of connecting the moisture sensor at each cycle of an oscillation circuit. CONSTITUTION:An output of an oscillation circuit 2 which performs an oscillation at a cycle determined by time constants of a resistance R1 and a capacitance C1 is connected to a CK input of a D-FF3 and two analog switches 4 are driven by an output E to switch the connection of a sensor 1. Hence, as a direction of current flowing through the sensor 1 is changed at each cycle of the circuit 2, no DC deterioration in the sensor 1 occurs. The output of the circuit 2 is applied to a voltage division circuit A comprising the sensor 1 and a reference resistance Rr and an output voltage B thereof is compared with a reference voltage C by a comparator 5. Thus, as moisture goes up, a resistance value of the sensor 1 falls and an output D of the comparator 5 goes to an H level with the voltage B becoming higher than C. As the moisture becomes higher than a set value, a circuit 6 repeats the connection and separation cyclically with the repetition of the cyclic connection and separation of the output D thereby outputting an intermittent sound from a speaker 8.
