Title: Resin sheet having fine irregular surface and manufacture thereof
Inventor: MORIGUCHI KAZUFUSA
IPC: B29C48/08
Filed: 1990-05-11
Abstract: PURPOSE:To manufacture a resin sheet with a fine irregular surface, which has a low friction coefficient and from which no frictional powder is generated, by bringing only one surface into contact with a cooling roll and cooling only the surface and forming fine irregularities having specific surface roughness to a surface not brought into contact in the melten sheet of a crystalline resin extruded from a mold. CONSTITUTION:A crystalline resin is used as a raw resin, and it is advantageous that high- density polyethylene and polyacetal are employed as such a resin. The raw resin is melted by an extruder, a molten resin sheet is extruded from a mold, and only one surface thereof is brought into contact with a cooling roll and solidified. Consequently, fine irregularities having center-line mean surface roughness of 0.2-3mum are formed to a sheet surface on the side not brought into contact with the cooling roll. The sheet surface brought into contact with the cooling roll is formed in a smooth surface. A pair of rolls such as nip rolls are used as the cooling rolls. Only both end sections of the molten resin sheet are brought into contact with a pair of each roll surface while only one surface of the molten resin sheet is brought into contact with the surfaces o the rolls at that time, the other surface of the molten resin sheet is brought to a free state not brought into contact with the rolles and the rolls are turned.

Title: Total radiation-type temperature measuring method
Inventor: TAMURA KIYOSHI
IPC: G01J5/06
Filed: 1983-07-06
Abstract: PURPOSE:To detect all wavelengths of a radiation energy by opening an aperture part to make the radiation energy, which is radiated from an object to be measured, incident directly into an inside tube from this aperture part and detecting the quantity of temperature rise of the inside tube at this time. CONSTITUTION:A total radiation-type temperature detector 10 is provided with a black body cavity-shaped inside tube 16 having an aperture part 14 provided with a shutter mechanism 12. An outside tube 20 surrounds the outside circumferential part of the inside tube 16 except the aperture part 14, and a vacuum layer 18 as a heat insulating layer is formed between the inside tube 16 and the outside tube 20. A heat insulator 22 surrounds the outside circumferential part of the outside tube 20. Plural thermocouples 24 detect a temperature rise of an inside wall face 16A due to heat radiation from the object to be measured. After the temperature of the inside tube 16 is set to a certain low value, the aperture part 14 is arranged closely to the object to be measured, and the shutter 12 is opened to make the heat radiation from the object to be measured into the inside tube 16, and the quantity of temperature rise in the inside tube 16 is detected at this time. The surface temperature of the object to be measured is obtained on a basis of this quantity of temperature rise.

IPC: H01L33/30
Filed: 1990-05-14
Abstract: PURPOSE:To shorten the length of an absorbing region thereby reducing the reflectance on the absorbing region while restraining the laser oscillation at the low temperature environment thereby enabling the light source for photoinstrumentation with high precision to be provided by a method wherein, at the coupling part of an exciting region with an absorbing region, the relation of the active layer width in the exciting region < the active layer width in the absorbing region is satisfied. CONSTITUTION:A waveguide structure is formed by holding the upper and lower parts of an active layer by clad layers comprising a p type-material and an n type material at low refractive index and having the band gap energy higher than that of the active layer. The title super luminescence diode is formed by coupling two laminated bodies in tandem comprising said bodies functioning as an exciting region (a) having an electrode capable of feeding current and another laminated body functioning as an absorbing region (b) having an electrode but not feeding current or having no electrode at all. At this time, the active layer width at the coupling part of the exciting region (a) and the absorbing region (b) satisfies the relation of the active layer width in the exciting region < the active layer width in the absorbing region. In such a constitution, the active layer width in the absorbing region is made wider than that in the exciting region at the junction part to make the active layer width constant or narrower toward the end of the absorbing region so that the reflectance on the absorbing region side may be sufficiently reduced thereby enabling the laser oscillation at low temperature to be restrained.

IPC: G09G3/36
Filed: 1987-05-20
Abstract: PURPOSE:To attain display of a picture high in definition by using plural pulses in one frame of period as selection signals supplied to respective gate lines. CONSTITUTION:In a time chart of the selection signals G and G', a picture signal 6 supplied to a drain line 6 connected to the drain of a thin film transistor 3, a picture element electric potential 7 equal to the potential of the lease of the thin film transistor 3 and a common electrode electric potential 8, the picture signal 6 is driven in terms of AC in the frame period T nearly setting the common electrode electric potential as a center. While the selection pulses G and G' are supplied to the gate of the thin film transistor 3, the picture element electric potential 7 gradually closes to the picture signal 6 and while the selection pulses G and G' are not supplied to the gate, it holds a certain electric potential. Since the selection pulses G and G' are short, the picture element electric potential 7 can not gradually close to the picture signal 6 with one pulse, so that it does with two pulses. If two pulses are insufficient, one more pulse is added. Thus, the display quality can be improved.

Inventor: MORITA MASAO
IPC: H04W4/04
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a communication system by which power consumed by a terminal equipment is suppressed. SOLUTION: A control means 16 of a center terminal 3 allows a communication means 15 to send start time information denoting a period for stopping communication processing by a terminal equipment 2 to the terminal equipment 2, a communication means 8 of the terminal equipment 2 receives the start time information and an interrupt means 12 interruption of power supply from a power supply 7 to the communication means 8. Then an interrupt release means 13 releases the interruption of power supply by the interrupt means 12 when a time count by a timer 10 reaches a start time (end time of pause period) indicated in the start time information. Thus, the communication processing by the terminal equipment 2 is stopped for a time when the center terminal 3 makes no communication with the terminal equipment 2 to suppress useless power consumption.

IPC: H02H7/28
Filed: 1977-10-14
Abstract: PURPOSE: To enable detection of the secondary winding shortage accident for a network transformer regardless of the amplitude of the current in the accident by detecting the occurrence of the accident by the power factor of the current.  
     CONSTITUTION: Since the respective power factor relays 6-1 to 6-2 and network protector reverse current breakage are correlated at timing, a network protector connected to the accident circuit detects the reverse current to thereby trip with a protector breaker PC-11. Then, the accident currents i f2 , i f3  are vanished to flow only the accident current i f1 , which is monitored by the relay 6-1 for detecting that the value of the delayed power factor of the accident circuit reaches less than predetermined value to thereby detect the secondary winding accident shortage of the network transformer NT-11 so as to generate a trip command to the corresponding primary feeder breaker 3-1 in order to thereby disconnect the accident point  from the system
