Title: Control method of plural unmanned carrier
Inventor: YAMAMOTO SHIGEHIRO
IPC: G05D1/02
Filed: 1989-12-15
Abstract: PURPOSE:To reduce unnecessary stop for preventing collision by judging whether to stop unmanned carriers or not as against a common area in consideration of a deceleration/stop state for preventing the present collision. CONSTITUTION:A control machine 1 judges whether to stop the unmanned carriers or not to the common area in the range of a supervisory distance decided as the distance required for a stop in correspondence with the travel speed of respective unmanned carriers 2a-2c. Not only a position relation as against the common area of respective unmanned carriers 2a-2c but also the deceleration/stop state for preventing the present collision is considered for judgement. The control machine 1 transmits a stop signal and an inter-zone distance with the common area to the unmanned carriers 2a-2c and the real distance with the common area is obtained on the unmanned carriers 2a-2c, whereby deceleration and stop are executed in correspondence with the distance. Thus, the stop far away from the collision area, which is beyond necessity, for preventing collision or the stop when it is not necessary can be avoided.

Title: Polarized light source device
Inventor: KUBOTA YOJI
IPC: G02F1/13357
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a polarized light source device provided with a polarized light conversion optical system, which is suitable for a high brightness light source such as a liquid crystal projector, small in size, compact in structure and low in manufacturing cost. SOLUTION: A polarized light transformation optical system 4 of this polarized light source device 1 is provided with a plate-formed polarized light film 6. Of p- polarized light component and s-polarized light component contained in the light flux I(2) emitted from a light source lamp 2, only the s-polarized light component of the light transmits a polarized light film 6 as it is, and p-polarized is reflected by the polarized light film 6 and returns to the side of the light source lamp 2 again. This reflected light passes through a quarter-wavelength plate 5 two times and becomes light of s-polarized light component, therefore, it is emitted by transmitting the polarizing film 6. As a result, polarized light flux I(out) consisting of only s-polarized light component is emitted.  As an optical element for separating polarized light, a plate- formed polarizing film 6 is used instead of a polarizing beam splitter consisting of a conventional prism synthesis body, therefore, the optical system can be configured small and compact, and can be manufactured inexpensively. Moreover, it is also possible to suppress an optical loss and a decrease in polarizing transformation efficiency.

Abstract: PROBLEM TO BE SOLVED: To provide a formed part made of amorphous alloy having improved wear resistance in addition to excellent characteristics inherent in amorphous alloy, and a surface hardening technology therefor. SOLUTION: A formed part composed essentially of amorphous alloy is heat treated under a reactive-gas-containing atmosphere and under the conditions of temperature and time within the amorphous region of the isothermal transformation curve (TTT curve) of the material, by which a ceramic hard layer is formed on the surface of the formed part.

Title: Damper thermostat
Inventor: MASAKU MASATOSHI
IPC: F25D17/08
Filed: 1989-12-18
Abstract: PURPOSE:To provide a damper thermo in which a screw is not rotated even under the greater movement of an arm and hence it does not influence the operation temperature by providing a resilient member between the arm and the screw such that the screw mounted on the arm is not rotated even though the arm is greatly moved. CONSTITUTION:An arm 109 makes contact with an eccentric cam 103 at one end thereof and is rotatably engaged with a frame 102, a screw penetrates through the arm 109. A bevel gear part 110 and a circumferential end surface part 111 are formed on a head 108' formed on one end of the screw 108. A resilient member 112 is provided between the arm 109 and a circumferential end surface part 111 of the screw head 108' so as to make contact with them. Hereby, even if the movement of the arm 109 is greater, frictional resistance of a contact surface among the resilient member 112, the arm 109, and the circumferential end surface 111 becomes high because the resilient member 112 applies force to the circumferential end surface part 111 of the screw head 108' by the spring 106 thereof in the direction of the contraction of the circumferential end surface part 111 at all times. Thus, the screw 108 is completely prevented from being rotated.
