Title: Time switch
Inventor: NISHIKAWA KAZUNORI
IPC: H01H43/02
Filed: 1987-06-18
Abstract: PURPOSE:To simplify the assembling and increase the accuracy of distances among contact plates by integrally forming projections blocking fixed contact plates from approaching a movable contact plate at the preset positions on a contact plate holder. CONSTITUTION:The free end section of a fixed contact plate 46 is brought into contact with the projection 721 of a contact plate holder 72, the free end section of a fixed contact plate 33 is brought into contact with the projection 722 of the holder 72, and a fixed contact plate 34 is brought into contact with the projection 732 of the holder 72. The projections 721-723 of the holder 72 block the contact plates 46, 33, 34 from approaching a movable contact plate at the preset positions respectively, and the preset distances are maintained between the movable contact plate and the fixed contact plates in each switch element in the nonoperational state in which a time switch is not set. The contact plates are thereby not required to be assembled with the preset step to a frame when assembled, thus the assembling is simplified. The contact plates are not deformed when assembled, and the accuracy of the distances among the contact plates can be increased.

Title: Manufacture of semiconductor device
Inventor: OGAWA HISASHI
IPC: H01L27/10
Filed: 1989-06-14
Abstract: PURPOSE:To increase the surface area of a memory node without increase of the number of processes by a method wherein the difference in etching rate between polycrystalline silicon doped with impurity and non-doped polycrystalline silicon is utilized to form a fin structure. CONSTITUTION:After impurity-doped polycrystalline silicon layers 5 and non- doped polycrystalline silicon layers 6 are successively and alternately built up, the layers are patterned by etching to expose the cross sections of the layers 5 and 6. If the cross sections of the polycrystalline silicon layers 5 and 6 are etched by isotropic etching, as the impurity-doped polycrystalline silicon is etched faster than the non-doped polycrystalline silicon, the impurity-doped polycrystalline silicon layer 5 parts are recessed and unevenness are formed on the cross sections. Then impurity is diffused into the whole polycrystalline silicon to form a memory node 7 having an unevenness on its surface. With this constitution, the memory node, i.e., a fin, having a large surface area can be formed by increasing the number of building-up processes only without increasing the number of the other processes.

Abstract: PURPOSE:To cope with the secular change of a sensor by correcting plural sensor outputs properly and controlling the titled device so as to obtain a reference output taught by a teaching means. CONSTITUTION:With a program switch (PSW) 40 is turned on, either one of sensors, e.g., a sensor 10A requested by a program detects a known physical quantity, a CPU 32 fetches the output of the sensor 10A and stores it in a RAM 36. Then the CPU 32 fetches an arbitray numerical data set in a data input device 42. The CPU 32 calculates a difference between the sensor output and a reference output and computes the corrected value. Said value is stored in the prescribed address of a PROM 26. In repeating the operations above, the output characteristic and the corrected value as to one sensor are decided and the result is stored in the PROM 26.

Title: Method for generating uniform liquid particle group
Inventor: KURABAYASHI TOSHIO
IPC: B01J2/04
Filed: 1982-09-01
Abstract: PURPOSE:To generate liquid particle groups having an extremely high degree of uniformity with less energy consumption by applying an acoustic wave or ultrasonic wave to the liquid flow from a nozzle or hole of a non-circular shape and generating the liquid particle groups having roughly equal sizes. CONSTITUTION:If liquid is flowed from a nozzle or hole of a non-circular shape like rectangular, elliptical shape or the like and the flow rate thereof is successively increased, the flat liquid film spread during the outflow is contracted by surface tension, resulting in a 90 deg. change in a flat direction and forming chain- like liquid flow. If the acoustic wave of a suitable frequency is applied to the chain-like liquid flow from a speaker, uniform particle groups equal to the frequency are generated in an extremely stable state. The liquid particle groups having high uniformity are obtd. by an extremely simple method and the granules produced by drying and solidifying such particle groups lend themselves to applications in a wide range.

Title: Measuring apparatus for three-dimensional shape
Inventor: YAMADA YOZO
IPC: G01B11/25
Filed: 1989-06-15
Abstract: PURPOSE:To obtain a measuring apparatus being excellent in a measuring speed and resolution, easy to handle and of low cost by a construction wherein an optical slit having a function of rotation or a function of shift of a lattice pattern is provided in the direction of progress of a condenser lens. CONSTITUTION:For a lattice-shaped pattern irradiation element, a light source, a diffraction grating 1 and a condenser lens 2 are used by arranging them linearly sequentially. Moreover, a slit having a function of rotation of a lattice pattern or such a function of shift of the lattice pattern as to vary the lattice pattern is provided in the direction of progress of light of the condenser lens 2. A light proceeding from a focal plane forms an image analogous to the diffraction grating 1 on the conjugate plane of the diffraction grating 1. When a diffraction grating (b) having lattice spacing (d) is employed, the light is diffracted in a direction given by sin (u) = nl/d ((n) is the order and l a wavelength), and when only the light of the first order is passed by using the slit, a point image (c) on a spectral plane 3 turns to be (d). Thus, the lattice image can obtain twice as large resolutions as (b). Rotation of the lattice-shaped pattern and a change in the shape thereof can be controlled only by shifting or rotating the slit.
