Title: Chucking jig
Inventor: FUJITA MASAHIRO
IPC: B23B31/36
Filed: 1991-12-27
Abstract: PURPOSE:To chuck a work without causing a deviation in the work by supporting the work by a support shaft and thrusting the work onto a thrusting part. CONSTITUTION:A thrusting part 11 is formed of a cylinder part 15 in which a fluid is sealed and a plurality of pistons 16 reciprocating in the axial direction of a support shaft 12 by the fluid pressure which are provided on the cylinder part 15, so that a work W is thrust onto the top end parts of the pistons 16. When the work W is supported by the support shaft 12 and thrust onto the top end parts of the pistons 16, the pistons 16 are protruded and retreated along the thrust surface of the work W and trust thereto. Since the work W is thus chucked with its axial line being conformed with the axial line of the support shaft 12, the work W is never deviated when rotated together with the chucking jig, and a precise working such as recessing to the outer circumferential surface of the work can be performed.

Title: Gas charging/exhaust device
Inventor: KAWAHARA MASAAKI
IPC: E04H15/20
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To shorten a worktime of forcible exhaust so as to improve workability by forming the secondary pressure intake port in a gas suction chamber, in the case of a gas charging/exhausting device provided with a gas sucking chamber having a gas suction port and a gas exhausting chamber having a gas exhaust port used for the purpose of the air column of an air tent and the air barrel of an air boat. SOLUTION: When the air column of an air tent is charged with gas by operating a motor M installed between a gas sucking chamber C1 and a gas exhausting chamber C2, a gas exhausting port 3 and the gas charging port of an air column are connected to each other by means of a hose and air exhausted from the gas exhausting port 3 is fed inside of an air column. On the other hand, when the air inside of an air column is discharged, gas suction port 2 and the gas exhaust port of the air column are connected to each other by means of a hose so that the air inside of the air column is exhausted by means of a suction force available from the gas suction port 2. At this time, when exhausting is made to progress and sheets themselves for forming the air column stick together and suction force becomes large, air is taken in from the secondary pressure intake port 4.  Thus by decreasing the suction force from the gas suction port 2, sheets themselves are separated from each other so as to open an air passage again.

Title: Superfine grain dispersed thin film and its production
Inventor: KATSURAGAWA TADAO
IPC: G02F1/355
Filed: 1991-12-05
Abstract: PURPOSE:To eliminate the distribution of large grains in the thin film by forming the thin film while irradiating the film surface with visible light. CONSTITUTION:A controlled light energy is imparted to the block, called a cluster, of more than several atoms while a thin film is formed to control the diameter of the fine grain. Visible light is used as the light energy. The visible light energy is used, because the light is the wavelength (energy) capable of being absorbed by the fine grain and the absorptivity varies with the grain diameter. Namely, only the grain of certain size range absorbs the light energy (wavelength) of specified range (light energy corresponding to shaded region). The grains in the film having absorbed light are heated, aggregated with the diffused atom or cluster close to the grain and increased in volume, the light is transmitted through the block of larger size, the growth is stopped, and the grain diameters are uniformized.

Title: Pen input device
Inventor: SANO TERUO
IPC: G06F3/0488
Filed: 1993-12-28
Abstract: PURPOSE:To input a character through single-time pen operation irrespective of the kind of the character by detecting a pen being operated and inputting a character assigned to a key selected with the pen or a corresponding symbol among entered symbols. CONSTITUTION:To input a lowercase English letter, a desired character key shape is tapped with the pen 7. Namely, a point is drawn on the desired character key. A tablet controller 13 detects the coordinates of the contact position of the pen 7 and supplies it to a CPU 17. The CPU 17 inputs and stores the detected coordinates in a RAM 19 in order, and judges whether or not detected coordinate positions are continuous. When the tapping operation is done, the detected coordinate positions become discontinuous, so the CPU 17 inputs the lowercase letter of the key tapped with the pen 7. To input an uppercase English letter, a circle is drawn on the key of the character to be inputted. The CPU 17 when judging that detected coordinate positions are continuous and judging that detected coordinate data are circular inputs the uppercase letter of the character assigned to the key where the circle is drawn.
