Title: Liquid crystal display device
Inventor: NAKAGAWA YUTAKA
IPC: G02F1/133
Filed: 1987-04-09
Abstract: PURPOSE:To obtain a display of an extremely high contrast ratio at a wide visual field angle by combining a negative type liquid crystal cell of high contrast, illuminating means provided with directivity and plate consisting of a group of microlenses. CONSTITUTION:The light transmitted through the display segments of the liquid crystal cell 1 with polarizing films has also directivity when the linearly progressing light provided with the directivity in the direction perpendicular to a substrate is projected on the liquid crystal cell 11 from behind the same. Light shielding property to the light in a front direction is extremely good in the non-display segments of the cell 11 and, therefore, the linear light toward the front direction is nearly completely shielded and there is no leakage of light, since the directivity is provided on the light. Said segments are, therefore, sufficiently dark even when viewed from the directions except the front. The directivity of the light transmitted through the cell 11 is, thereupon, eliminated by the plate 14 consisting of the group of the microlenses disposed on the front face of the cell 11 so that the display light is scattered over the wide visual angle. The extremely high contrast ratio is thereby obtd. over the wide visual field range.

Abstract: PURPOSE:To reduce an error and to speed up decision making by comparing the developed voltage of a resistance ladder circuit which consists of a differential resistance and temperature adjusting resistances and is powered on intermittently by a microcomputer with the developed voltage of a temperature sensing element. CONSTITUTION:A desired temperature is set with switches 11-14 and inputted to a microcomputer muCOMP4. The muCOMP4 is provided with the resistance ladder consisting of resistances 5-8 corresponding to the switches 11-14 and the differential resistance 21 for turning on and off an unshown compressor reperatedly at a specific period, and a voltage developed at the connection point of resistances 9 and 10 is inputted as a reference voltage V+ to the plus terminal of a comparator 3. A voltage V- at the connection point of the temperature sensing element 1 and a resistance 2 is inputted as a detected temperature to the minus terminal of the comparator. When the V- is higher than the V+, the output of the muCOMP10 is applied to turn on a TR17 through a resistance 16, and a relay 15 closes a contact 18 to put the compressor in operation. Consequently, the on-off period is shortened and the decision making time of temperature detection is shortened to reduce a detection error.

Title: Active filter control circuit
Inventor: SANO KOICHI
IPC: H02J3/01
Filed: 1994-04-25
Abstract: PURPOSE:To prevent that a harmonic current is enlarged to an extent higher than the amount of that generated by a harmonic generating source on the load side and a load capacitor is heated by detecting, when enlargement of harmonic current on the load side is generated, such enlargement to control a compensating current to zero. CONSTITUTION:When enlargement of harmonic current IL is generated by addition of a load such as a capacitor which becomes a low impedance to harmonics in the load side, harmonics included in a system current Is increases to enlarge a band-pass filter output signal Pt. Thereby, a DC signal Pq exceeds a preset value Pr, making high a comparator output signal Ps. Moreover, its output signal Ps appears in an output of a second gate circuit 16. In this timing, the output signal Ps is inverted to a low level to become a first gate signal Ga. Accordingly, enlargement of harmonic current IL is detected and the first gate circuit 13 turns off, controlling the compensating current Ia to zero and also an active filter operation is turned off, not assisting enlargement of harmonic current.

Title: Disposal of sludge
Inventor: MIURA MITSUGI
IPC: C02F11/06
Filed: 1980-06-24
Abstract: PURPOSE: To lower a cost for incineration of sludge containing a large amount of water, by adding a substance having a combustibility and a filtration-assisting property into sludge or filtration lees generated in filtration-dewatering sludge, filtration-dewatering the mixture, gelatinizing the resultant filtration lees, and dewatering it.  
     CONSTITUTION: Sludge or filtration lees generated in filtration-dewatering sludge is dehydrated by addition of a filtration/combustion-assisting agent, e.g. sawdust, chaff, straw or the like. Sodium alginate and then calcium chloride are added to the sludge, or a water glass solution is added to the sludge. Thereafter, the mixture is adjusted at pH about 7W8, to gelatinize the filtration lees. The obtained gel has a structure from which contained water can be quite easily separated. Consiquently, when the gel is pressed, free water is easily separated, and a crisp granular solid having a water content or 65% is obtained. The water content of the obtained granular solid is lowered at a rate such that the solid will burn hypergolically. As a result, the gel burns when it is charged in a domestic waste material incinerator, and a fuel consumption can be saved.

IPC: G06F15/78
Filed: 1992-03-10
Abstract: PURPOSE:To easily attain the measurement of an outside pulse, and the pulse output of a variable cycle or a variable frequency by using the same reference timer. CONSTITUTION:A difference between the content value of a reference timer 1 at the previous edge and the content value of the reference timer 1 at the present edge is calculated by a subtracter 6 by a rising edge and a falling edge being the changing point of the outside pulse, and the calculated result is stored in a calculated result storage device 9. On the other hand, at the time of the generation of a digit borrow(borrow) due to the calculation of the difference, the digit overflow of the reference timer 1 obtained by the calculated result is invalidated by a digit overflow flag 10, so that it is not necessary to initialize the value of the reference timer 1 at the edge of the outside pulse, and the value can be always counted from the minimum value to the maximum value. At the time of the pulse output, the content value of the reference timer 1 is compared with the content value of a compared value storage device 4, and the value for a level width is added to the present timer value, so that a timer value at the time of the next inversion can be predicted.

Title: Disk elevating device of video disk player
Inventor: MIKI YUUJI
IPC: G11B17/051
Filed: 1984-04-28
Abstract: PURPOSE:To prevent a disk from deforming through simple circuit constitution by moving up and down the disk by utilizing the discharge of a capacitor which is charged to a source voltage for downward movement between two power sources which move up and down the disk. CONSTITUTION:If a power failure occurs while a support is elevated, a positive source voltage (Vcc) applied to the emitter of the 2nd PNP digital transistor (TR) drops, so the TR is cut off between the collector and emitter. At this time, a diode D1 is turned on with the negative charge from the capacitor C to hold the base potential of the 1st PNP digital TR17 minus, so the TR turns on. On the other hand, the emitter side of a PNPTR15 is also held at a minus potential by the capacitor C, so it turns on. Consequently, a transient current flows in the order of the earth 20, a DC motor 2, a resistance R4, the PNPTR15, and the capacitor C and a DC motor 2 reverses to disengage a drive gear 3 and a friction gear 7 from each other, thereby lowering the support.
