  • Publication number: 20060091588
    Abstract: To provide a production method of a polycrystalline ceramic body with excellent density, a preparation step, a mixing step, a forming step and a heat-treating step are performed. In the preparation step, a coarse particle ceramic powder, and a fine particle powder having an average particle diameter of ? or less of the average particle diameter of the coarse particle ceramic powder are prepared. In the mixing step, the coarse particle ceramic powder and the fine particle powder are mixed to produce a raw material mixture. In the forming step, the raw material mixture is formed to a shaped body. In the heat-treating step, the shaped body is heated and thereby sintered to produce a polycrystalline ceramic body. In the heat-treating step, a temperature elevating process and a first holding process are performed and at the same time, a second holding process and/or a cooling process are performed.

  • Patent number: 6077049
    Abstract: A compressor has an odd number of aligned pairs of cylinder bores. A double-headed piston is accommodated in each aligned pair of bores. The time at which gas is discharged from each cylinder bore is different from that of all of the other cylinder bores. The compressor has a pair of reducing devices, one reducing the pulsation amplitude of the gas discharged from the front cylinder bores and the other reducing the pulsation amplitude of the gas discharged from the rear cylinder bores. The reducing devices reduce the gas pulsation amplitudes of the front and rear cylinder bores at a substantially equal rate. Each reducing device includes a discharge chamber for receiving the gas discharged from the associated cylinder bores and a discharge passage connected to the discharge chamber. The discharge chambers of the reducing devices have equal volumes, and the discharge passages of the reducing devices have equal lengths and equal cross-sectional areas.

  • Patent number: 5879416
    Abstract: A rectangular case of a battery has cover, which is inserted into an open end of the case with the peripheral edge thereof butted against an inner periphery of the case, forming an interface to be welded. In order to form an equal weld penetration depth, the welding of the corners of the weld interface and straight sides thereof is carried out differently. For example, when the corner of the weld interface is welded, the laser beam is aimed at a portion offset outside the corner of the weld interface while the laser beam is applied right on the weld interface when the straight side is welded. Each portion on the straight sides is, preferably, welded before the above main welding for temporary setting.

  • Patent number: 5517017
    Abstract: A position detection element 4 is formed by sequentially depositing an X-axis resistor film 5, a photoconductive film 6 and a Y-axis resistor film 7 on one surface of a glass substrate 2 which is a transparent member. Further, a light screening film 3 is formed on the other surface of the glass substrate 2. At that time, a pin hole 31 through which light is transmitted is formed at a central portion of the light screening film 3. Where the position detection element 4 and the light screening film 3 are formed integrally with and on the glass substrate 2, mounting of the glass substrate 2 on a casing of a sensor enables the position detection element 4 and the light screening film 3 to be mounted on the casing of the sensor, thus improving the mounting property of the light position detection element 4 and the light screening film 3 on the casing.

  • Patent number: 5455415
    Abstract: An insolation sensor for detecting a substantial insolation direction from the sun including a light shading film an aperture defined therein and provided on one of the surfaces of a glass substrate. A position detection element having a photoelectric conversion film made of a semiconductor is formed on the other surface. The rays of light from the sun are incident as a spot beam H onto the position detection element through the aperture. The position detection element detects a center of the intensity of photocurrent at the beam receiving portion. Therefore, even when the intensity of each of the direct rays and scattered rays from the sun change on the ground depending on the weather conditions, the center position of the distribution of the insolation intensity can be detected in accordance with the weather conditions, and a substantial insolation direction can be detected.

  • Patent number: 4461475
    Abstract: A game machine has a plurality of targets which unpredictably come out and disappear from their corresponding holes at the surface of a table on a game stand. A player can only strike targets which are positioned above the surface thereof. A main shaft is provided with the target on its upper end and is supported by bearings in such a manner that it can rotate and move up and down. A plunger disposed at the periphery of the main shaft is magnetically attracted by an electromagnetic solenoid. When raised, the main shaft always faces a predetermined direction due to an action of permanent magnets. Hitting of the target can be detected by monitoring abrupt large fluctuations in current flowing through the solenoid during a period of time that the target is caused to appear above the table.
