Inventor: WAKIZAKA TATSUYA
IPC: E04C3/34
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To remarkably increase the post strength by making the outside surface and the inside surface as relief surface, surrounding the periphery of a post main reinforcement with a cast iron plate formed like a cylinder having a closed section, and placing concrete in the interior thereof. SOLUTION: In a factory, a cast iron plate 12 is formed like a cylinder having a closed rectangular section, and the inside surface 12a and an inside surface 12b are formed as projecting and recessed uneven surface 20. The cast iron plate 12 is carried in a building site, erected in such a manner as to surround the periphery of the post main reinforcements 24, 24, and concrete is post-placed to form a post 10.

Title: Discharge gas temperature control system for scroll refrigerator
Inventor: HIRAOKA SEIJI
IPC: F25B1/00
Filed: 1995-01-20
Abstract: PURPOSE: To suitably hold a compressor discharge gas temperature even in a transient operation and to efficiently operate at the time of stably continuous operation by varying a liquid injection control temperature in response to the discharge gas temperature altering state of the compressor. CONSTITUTION: When the discharge gas temperature of a compressor 1 is detected to become a specific value or more, the discharge gas temperature control system of the compressor 1 opens a solenoid valve 5 for injection, and closes the valve 5 at the specific value or less to control the discharge gas temperature. If the discharge gas temperature is in an abrupt rising ratio of a certain specific value or more, the injection operating temperature value is injection controlled by a lower value than the normal set value. Thus, cooling is early conducted to prevent the temperature rise due to the follow-up delay, and even in the transient operation of the compressor 1, the discharge gas temperature gas can be suitably held to be operated, and the power of the compressor 1 is not wastefully operated.

Abstract: PURPOSE:To make it possible to detect the jamming of paper, by providing a rotation detection means for detecting the rotation of a rotary body rotating by the friction force with printing paper and detecting the jamming of printing paper on the basis of the detection signal thereof. CONSTITUTION:A paper feed motor 2 rotates by an indicated angle by a paper feed signal to rotate a platen 3, a drive shaft 8 and a paper feed tractor 4 to deliver printing paper 1 to the direction shown by an arrow. The paper jamming detecting rotary body 5 provided below the drive shaft 8 rotates by the friction force with the printing paper 1 with the delivery operation of the printing paper 1. Because a magnet 6 is preliminarily provided to said rotary body 5, a pulse like output wave form is obtained from a magnetic sensor 7. At this time, if the jamming of the printing paper 1 is generated, the generation of a pulse signal is eliminated and, by monitoring said output wave form, the generation of the jamming of the printing paper 1 can be detected. By the method, even if either of a cassette paper or a continuous paper is used, paper jamming can be detected.

Title: Graphic conversion system
Inventor: OSUGA HIROJI
IPC: G06T9/00
Filed: 1985-01-18
Abstract: PURPOSE:To improve the arithmetic processing efficiency by calculating previously an arithmetic parameter whose X.Y coordinates are fixed within a scan of a picture scanner by an element-based dividing operation for each scan and using said arithmetic parameter to perform a converting operation. CONSTITUTION:A pattern 2 is shown in a black color on a white drawing 1 to be read, and the scan is carried out along a locus 3. A run length vector 4 shows a specific distance between a start point and an end point during which the black pattern 2 is continuous within a scan. A converting operation is carried out by means of equations I and II where the start and end points of the vector 4 are defined as (x) and (y) respectively together with the coordinate values xt and yt obtained through conversion of the coordinate values (x, y) and constants (a-h). The equation I is calculated only once at first for each change of the scan line; while the equation II is applied to the run length data within the same scan line. Thus the result of calculation is used in common within the same line. This improves the arithmetic processing efficiency with a graphic conversion system.

IPC: G05D23/00
Filed: 1991-01-25
Abstract: PURPOSE:To permit the stabilization of the temperature of an instrument, installed on a base on the surface of moon, easily by a method wherein the instrument is provided with a heat pipe, connecting a pipe for pouring liquid reserved in a vessel into the ground of moon and the ground of moon, into which the liquid is poured, to the instrument, whose heat is to be controlled, thermally. CONSTITUTION:Liquid (water, for example) 1, forming a heat sink under ground, is reserved in a tank 2 and pipes 3, connected to the tank 2, are burried under the ground. Holes are bored on the pipes 3 at positions lower than 1m under the ground to impregnate the mud and sand 4 under the ground with the liquid 1 supplied from the tank 2. The mud and sand 4, having the temperature of about -30 deg.C, deprives the liquid 1, impregnated under the ground, of the heat thereof and the liquid 1 is solidified. In this case, the pipe 3 is equipped with a heater (not shown in a diagram) to control the solidifying time of the liquid 1 so that the sufficient amount of the liquid is impregnated into the mud and sand 4. The heat sink, constituted under the ground in such a manner and having a big heat capacity, is connected to an instrument on the surface of the moon, whose heat is to be controlled, through the heat pipe 5 thermally to stabilize the temperature of the instrument.

Abstract: PURPOSE: To obtain the internal wall of pipe with high-quality coating layer of uniform thickness by uniformly coating and soldifying liquid lining material on the internal surface of pipe of metal which is heated, rotated, and reciprocated.  
     CONSTITUTION: A metal pipe P is placed on rollers 7, 7', and one end of the pipe P is covered with blind lid 20, the other end with lid 21 having hole 22 to pass a pike. Screw lever 15 is operated to cause rollers 13, 13' to press the pipe P from the top, and the roller 7, 7' are rotated by motor M. Then, the pipe P is heated from the outside by heater 16 ant the pipe P is reciprocated with proper stroke by displacing rollers 7, 7' through handle 12 manipulation. Keeping the pipe P heated and rotated, pike 19 containing lining material 23 is inserted into the pipe P through the hole 22. The pike 19 is rotated 180° to inject lining material 23 all over the surface of the pipe P. The roller 7, 7' are rotated faster so that centrifugal force and the reciprocal motion of the pipe P causes uniform coating. This motion is continued until lining material is solidified.
