Title: Production of ceramic microball
Inventor: OZAKI YOSHIHARU
IPC: C04B35/46
Filed: 1986-05-10
Abstract: PURPOSE:To produce the titled ball having a uniform particle size with a simple method by dispersing a solution dispersed very fine particles in an alcoholic solution into a liquid paraffin in a small dropping state, followed by drying and calcining it. CONSTITUTION:The various kinds of ceramic fine particles or alkoxide particles capable of forming ceramic fine particles by hydrolyzing and calcining are dispersed in the alcoholic solution to prepare a suspension solution or a sol. And then, the suspension or the sol is dropped in the liquid paraffin which does not mix with the suspension or the sol, followed by dispersing to form spherical particles thereof. The obtd. particles are filtered, washed, dried and calcined, after evaporating alcohol by heating the particles to form the titled balls. The particle size of the obtd. spherical particles is controlled by a diameter of an orifice for dropping said particles and a concentration of the suspension or the sol, thereby easily obtaining the titled ball which is near to sphericity and has uniform particle size.

Abstract: PURPOSE:To stabilize the temperature of a floor heating warm water by bypass ing the warm water of a return tube to a forward tube when the temperature of the floor heating warm water generated by heat exchanging by a heat exchanger is a pedetermined value or more. CONSTITUTION:A heat exchanging unit 5a for generating floor heating warm water is provided integrally with a heat exchanger 5, and warm water generated from the unit 5a is circulated to a floor heating panel 3 via a return tube 11 of a warm water route. In this case, the temperature of the water in the tube 11 is detected by a temperature sensor 12 provided at the tube 11, and when the temperature detected by the sensor 12 is a predetermined value or more, the water of the tube 11 is switched by a switching valve 14, and bypassed to a forward tube 13 via a bypass tube 15. Thus, the floor heating warm water is obtained by thermal conduction of the exchanger 5, and the temperature of the floor heating water can be stabilized.

Title: Liquid crystal display device
Inventor: MOCHIZUKI AKIHIRO
IPC: G02F1/133
Filed: 1984-05-29
Abstract: PURPOSE:To accumulate and hold the written content of a display without a holding voltage by converting or transferring said content, in the state of having no holding voltage, to a focal conic state and Grandjean state which are the bistable state of a cholesteric state. CONSTITUTION:The figure shows the relation of the change in the impressed voltage- light transmittance of mixed cholesteric-nematic liquid crystals. The voltage VH of, for example, double the holding voltage Vd is first impressed among all the electrodes of the matrix to make the liquid crystals into the H (homeotropic) state. All the liquid crystal molecules 1 in the H state are in the same direction as the electric field direction and the incident light past a polarizing plate 3 arrives at a polarizing plate 4 without changing the angle of polarization but the angles of polarization of the plates 3, 4 vary by 90 deg. and therefore the light is not passed through and the dark state is maintained. When the voltage is made zero from this state, the liquid crystals attain the F0 state which is the cholesteric phase. The same F state as F0 is attained even if the Vd is impressed again. The component of the light passing through the plate 4 is then generated and the bright state is created. Even if the 2Vd is decreased to the Vd, the H state can be maintained. The continuous display of the image without the holding voltage is thus made possible.

Abstract: PURPOSE:To reduce an electric power consumption of a semiconductor integration memory cell  by forming a vertical cross section of a field oxide film for a memory cell FET and forming an n  channel on the midway of the depth to completely shield a current at the time of reading ''0''. CONSTITUTION:An n<+> type source 12 and a drain 11 (bit wire B) are formed on a p type substrate 4, ions are implanted therebetween, and n channel 2 is formed in deep portion, and a p  type charge storage layer 8 is formed in shallow portion.

IPC: H01L29/792
Filed: 1991-05-13
Abstract: PURPOSE:To prevent data holding capacity from lowering due to repeated writing/erasure of data by an arrangement wherein a first floating gate only capable of electrical writing and a second or third floating gate capable of electrical writing/erasure coexist. CONSTITUTION:When data not to be rewritten is written in, a drain 3 and a semiconductor substrate 1 are grounded and a high voltage is applied on a control gate 15 and a source 2 thus writing the data into a first floating gate 11 through an insulation film 10. When a data to be rewritten is written in, a high voltage is applied onto the control gate 15 and the drain 3 thus writing the data into a second floating gate 13 through a second insulation film. Since the data is written into the first floating gate only one time, qualitative deterioration of the first insulation film is suppressed and the data is held in the first floating gate 11.

Abstract: PURPOSE:To prevent latch up of the device by a method wherein a P-well is surrounded with a P type layer, and a P type MOSFET constructed by both thereof and a gate electrode is connected in parallel with an N type MOSFET in the well. CONSTITUTION:A gate electrode 21 is arranged between the P-well 13 of an N type substate 10 and the P type layer 20 surrounding the P-well thereof interposing an insulating film between them to form the FET 22, and is connected in parallel with the N type FET 15 in the P-well 13. A parasitic diode 23 is generated between the P type source of the P type FET 11 and the N type substrate. A surge to invade from an output terminal OUT is by-passed according to the FET 22 and the diode 23 to prevent destruction, and because the P type layer 20 is surrounding the P-well 13, the resistance value between the collector of the lateral FET and the base of the vertical FET is increased, and a current to flow in the substrate 10 or the well 13 is limited. Accordingly a voltage drop according to base resistance is reduced, and latch up is prevented. When resistance of the P type layer 20 is increased, the voltage drop according to resistance can be reduced than the VBF of the FET.

Abstract: PURPOSE: To improve the adherence of a printing plate by a method wherein a plate tail inserting member is supported to the tail side end part of a machine plate movably from a plate hold-down roll side along the peripheral surface of a plate cylinder. CONSTITUTION: By retreating a piston rod 24 through the actuation of a second air cylinder 23, a lever 20 is pivoted clockwise about a rocking cylinder shaft 21, resulting in abutting a plate hold-down roll 22 against the position corresponding to a rolling bar hole on the peripheral surface of a plate cylinder 1. At this time, since a third air cylinder 25, which is pivotally attached to the central end part 20c of the lever 20, is also moved together with the pivoting of the lever 20, a pad 28 is moved to the plate cylinder 1 side so as to come close to the plate cylinder 1. When the plate cylinder 1 is pivoted clockwise starting from the state just mentioned above, a machine plate is pushed by the hold-down roll 22 against the peripheral surface of the plate cylinder 1 so as to be wrapped in order to be adhered to the periphery of the plate cylinder 1.  Since the machine plate is installed under the state being adhered to the peripheral surface of the plate cylinder, neither the folding of a printing plate nor the cracking of the plate develops.
