Title: Heat insulation material
Inventor: TSUGE SHIGEKIYO
IPC: E04B1/80
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent corrosion of glass fiber due to moisture and lowering of heat insulation and to prevent the occurrence of environmental pollution due to flying of fiber small pieces by a method wherein a glass fiber plates are placed in a plastic bag, and a pressure-reduced, compressed, and sealed heat insulation material is used. SOLUTION: A glass fiber plate 2 having an ordinary thickness is placed in a pressure reduced and compressed state in a plastic bag 3 having an air hole 5 to which a plug 4 is attached, and a peripheral edge part 3A of a bag 3 is welded in a state to protrude from the edge of one surface of the fiber plate 2. In order to place the fiber plate 2 in the bag 3, the fiber plates 2 cut to given lengths are inserted in a bag-form plastic sheet and set at a press mold. As the internal part of the bag 3 is reduced in a pressure through a vacuum route, the peripheral edge part 3A is heat- fused electrically or through steam heating and a method described above is employed. The obtained heat insulation material 1 is used such that the bag is filled with air by pulling out a plug 4 to expand the fiber sheets 2, and thereafter the plug 4 is fitted therein again.  This constitution reduces the occurrence of corrosion and lowering of heat insulation ability and the occurrence of environmental pollution due to flying through filling of the bag 3 therewith.

IPC: B64G1/26
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To quickly perform a spacecraft orientation procedure with no or almost no support by a ground tracking station. SOLUTION: The x-axis of a spacecraft 20 is set parallel to a solar beam by using a solar sensor 50 in order to search an earth in accordance with a ground tracking station or autonomously supplied instructions by using a gyro sensor 52 or an earth sensor 48.

Title: Control system for traffic signal
Inventor: NISHIDA YOSHIKO
IPC: G08G1/08
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To shorten the time for a bus on a regular route to temporarily stop for waiting a signal by providing a sensor arranged in front of a traffic signal for detecting the bus on the regular route traveling toward the traffic signal, and performing control so as to shorten the turning-on time of 'red' signal on the basis of the velocity of the bus on the regular route calculated on the basis of this sensor signal. SOLUTION: Sensors S1-S5 for detecting bus on regular route generate sensor signals only when the bus on the regular route passes on the respective sensors. The sensors S1 and S2 are arranged at a prescribed interval L in front of a traffic signal 4a and the sensors S3-S5 are arranged in the rear of a T-shaped crossing 2. A traveling velocity V of the bus 3 on the regular route is calculated from a time difference T in the case of inputting sensor signals SS1 and SS2 from the sensors S1 and S2 to a controller 5. When this traveling velocity V is lower than a set velocity V0, slow driving caused by traffic jam is judged and the time of turn on the 'red' signal in the traffic signal 4a is shortened to a preset time.

Abstract: PURPOSE:To expand the dynamic range by using a clear signal so as to discharge part of a stored charge in a charge modulation element picture element for a period from resetting till a succeeding read operation thereby changing an output current in response to the luminous quantity. CONSTITUTION:Let one filed period after reset operation is finished be T, a 1st gate voltage VG1 is applied for a horizontal blanking period after elapse of a time T/ 2.

Furthermore, for a horizontal blanking period after elapse of a time 3/4T after the reset operation is finished, a 2nd gate voltage VG2 is applied to a line. Thus, positive holes being 1/2 or over the saturation positive hole number depending on a difference VA-VRD are discharged to the substrate for a period of time 3/4T. As a result, an output characteristic depending on an incident luminous quantity is obtained with respect to a range of incident luminous quantity of 0 2LSAT.
