Title: Lighting system
Inventor: IWAI MICHIKO
IPC: H05B37/02
Filed: 1994-09-27
Abstract: PURPOSE: To obtain the comfortable lighting system, which can save the energy. CONSTITUTION: Detection region of a human body detecting sensor unit 1 provided with a pyroelectric element is divided into plural detection regions. Human body detecting signal can be obtained from each divided detection region. In the case where a person passes through within the detection region, the human body detecting signal is continuously output with a short interval. On the other hand, in the case where a human body stops within the detection region, interval between the human body detecting signals is prolonged. A control unit 3 discriminates whether the person passes through or stops within the detection region on the basis of the interval between the signals.  In response to a result of the discrimination, a luminaire 41 is controlled for modulation through a light modulating signal output unit 5 so that the illuminance detecting signal by an illuminance sensor unit 2 achieves the predetermined level. The comfortable lighting environment corresponding to the behavior of a person is thereby obtained, and the energy can be saved.

Title: Manufacture of lead-acid battery
Inventor: HATANAKA TAKESHI
IPC: H01M4/22
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To improve the discharge capacity and prevent the deterioration of storage characteristic by chemical conversion charging a non-chemical conversion treated plate in a sulfuric acid solution to which mannitol or mannitol and hydrazine sulfide are added, and removing the mannitol and hydrazine sulfide by washing. SOLUTION: A non-chemical conversion treated plate is subjected to a battery jar chemical conversion treatment or pole plate chemical conversion treatment by use of a diluted sulfuric acid solution to which mannitol or mannitol and hydrazine sulfide are added as chemical conversion solution. The resulting pole plate is washed with water to remove the added mannitol and hydrazine sulfide. Although mannitol exhibits the action of forming an ideal pole plate structure in chemical conversion treatment, the lead dioxide of the pole plate is gradually reduced to lead sulfide when the mannitol is preset in the pole plate, and the capacity tends to be reduced by the reduction of lead dioxide or the change of the structure.  Since the pole plate manufactured under the coexistence of mannitol and hydrazine sulfide has many pores, the reaction area is increased to make advance easy for the reduction reaction. Thus, these additives must be removed.

Filed: 1992-07-15
Abstract: PURPOSE:To move an indoor mobile robot to a target position with higher accuracy by surely detecting the position of the robot in each room even if a room where the robot moves is divided into plural rooms by the walls. CONSTITUTION:An indoor mobile robot 1 identifies the room where the robot is presently moving and transmits the identification signals and the timing pulses through an identification signal transmitter 2 and a timing pulse transmitter 3 respectively. The ultrasonic waves are transmitted by the ultrasonic wave transmitters 6-1 and 7-1 or 6-2 and 7-2 whose signals are coincident with the identification signal received by the identification signal receivers 8-1 and 8-2, as soon as the timing pulse receivers 9-1 and 9-2 receive the timing pulses. Then the robot 1 receives the ultrasonic waves through the ultrasonic receivers 4 and 5. Thus the robot 1 detects its own position in each room based on the time count value covering the time point when the timing pulses are received through the point of time when the ultrasonic waves arrive and moves on a designated traveling route CL.

Title: Liquid crystal display device
Inventor: YAMAHARA MOTOHIRO
IPC: G09F9/35
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To effectively improve the problem of coloring by controlling the ratio of the change in the refractive index anisotropy of a liquid crystal material in a liquid crystal layer with wavelengths of light to the change in the refractive index anisotropy of an optical phase difference plate to such a range that no coloring is produced in a liquid crystal screen depending on the viewing angle. SOLUTION: Optical phase plates 2, 3 have principal refractive indices na , nb , nc in different three directions satisfying na =nc >nb . Since only one optical axis is present, the phase difference plates 2, 3 are uniaxial and show negative refractive index anisotropy. The ratio of the change in the refractive index anisotropy of the liquid crystal material in the liquid crystal layer 8 with wavelengths of light to the change in the refractive index anisotropy of optical phase difference plates 2, 3 with wavelengths of light is controlled to such a range that coloring of the liquid crystal screen depending on the viewing angle is not caused. Therefore, in a divided state of the liquid crystal layer 8, the compensation function of phase differences by optical phase difference plates 2, 3 can be combined with the best characteristics.

Abstract: PURPOSE:To increase the durability by providing a thrust member with a circular arc form section, a rubber tube provided at the inner side of the thrust member, a wedge sliding with the thrust member, and a guide to adjust the inclination to the displacement direction. CONSTITUTION:A rubber tube 5 is expanded by feeding a hydraulic pressure, a thrust member 1 is expanded through a wedge 4, and a crack is generated in a surrounding base rock. And in this case, projections 2 formed at both ends of the member 1 are slid inside a guide 3, and displaced on the bisector of the member 1 parallel to the sliding surface between the projections 2 and the guide 3. And the member 1 is displaced while maintaining the right balancing condition, and never generates a single swing even though the sliding resistance between the member 1 and the wedge 4, and the external pressure applied to the member 1 are uneven. As a result, a trouble to hurt the tube 5 by pinching the tube 5 in a gap between the member 1 and the wedge 4 can be prevented. Consequently, the durability can be increased.

IPC: H02M7/48
Filed: 1992-09-01
Abstract: PURPOSE:To prevent a control circuit from erroneously operating due to currents flowing through a circuit. CONSTITUTION:In a discharge lamp lighting device 1, a main circuit portion 2 that constitutes an inverter is provided in a section 3 on a substrate and a control circuit portion 4 including an IC 16 is provided in a section 5. Further, in the discharge lamp lighting device 1, an IC stabilized potential line 25 of the control circuit portion 4 is branched off from a main circuit stabilized potential line 23 of the main circuit portion 2. An IC high potential line 15 is connected to a power supply high potential input terminal Vdd of the IC 16. The IC stabilized potential line 25 is connected to a stabilized potential terminal GRD of the IC 16. An output terminal Out of the IC 16 is connected to the gate of an FET 18 of the main circuit portion 2. With this constitution, a magnetic field applied to the control circuit portion 4 including the IC 16 can be suppressed to a low level because magnetic fields generated by a main circuit high potential line 13 and the IC stabilized potential line 25 counteract a magnetic field generated by the main circuit stabilized potential line 23. As a result, erroneous operation of the control circuit portion 4 including the IC 16 can be prevented.
