Title: Pigment-coated phosphor
Inventor: INOUE KIYOSHI
IPC: C09K11/08
Filed: 1983-06-09
Abstract: PURPOSE:To provide a pigment-coated phosphor with improved properties for a blue color phosphorescent surface of a color cathode ray tube, prepd. by applying cobalt aluminate blue pigment with a specified cobalt content to the particle surface of a blue color phosphor. CONSTITUTION:A cobalt aluminate blue pigment having a cobalt content of 35wt% or higher is applied to the surface of particles of a blue color phosphor. The phosphor to be coated with the pigment is a silver-activated zinc sulfide phosphor having a particle diameter of 4-10mum. The concn. of silver can be reduced by the amount of the pigment applied and 0.013-0.023wt% will suffice. For reduced amt. of the pigment, the phosphor should have a large particle diameter and a small specific surface area. When the particle diameter is smaller than 4mum, too much pigment is attached to obtain a pigment-coated phosphor having satisfactory pigment separation, etc. When it exceeds 10mum, application of pigment to the phosphorescent surface is rendered technically difficult.

Title: Read only memory circuit
Inventor: SHIODA FUMIO
IPC: G11C17/12
Filed: 1982-06-14
Abstract: PURPOSE:To attain low power consumption with using almost no power in a memory cell, by constituting that two power supply lines having two different voltages are led to the storage element and storing binary information depending on the connection to either of the two power supply lines. CONSTITUTION:In connecting a terminal 7 of a switch 2 to the 1st power supply line 5, when the switch 2 is conductive with a readout instruction line 1, a readout line 3 is equal in potential of the 1st power supply line 5. Further, when the terminal 7 of the switch 2 is connected to the 2nd power supply line 6 and the switch 2 is conductive with the readout instruction line 1, the readout line 3 is the same potential as the 2nd power supply line 6. Thus, once storing whether the terminal 7 of the switch 2 is connected to the 1st power supply line 5 or to the 2nd power supply line 6 as the content of the memory, the content of the memory is discriminated depending whether the voltage of the 1st power supply line 5 is outputted to the readout line 3 or the voltage of the 2nd power supply line 6 is outputted when the switch 2 is conductive.

Filed: 1988-04-27
Abstract: PURPOSE:To obtain an electron emitting element with high quality and little dispersion in characteristic without applying the foaming process by arranging an electron emitter insulated from electrodes on the side end of an insulating layer formed between opposite sections of the electrodes. CONSTITUTION:When the voltage of several V-hundreds V is applied, electrons are emitted from near an electron emitter 3, where the thickness of an insulating layer 5 is several Angstrom -severalmu and the electron emitter 3 is made of a metal material such as Au, Ag, Cu, Pt, Pb or their alloy or an oxide such as SnO2, In2O3, PbO or a mixture of these metal materials, alloys, oxides. The applied voltage to emit electrons has a threshold value, this threshold value depends on the thickness of the insulating layer 5, i.e., the distance between the electrodes 1 and 2 at the end face of the insulating layer 5, and materials of the electron emitter 3 and the electrodes 1 and 2. The electron emitter with a stable structure can be thereby formed without applying the foaming process even if the distance between the electrodes having the electron emitter is made very narrow.

IPC: G05D1/02
Filed: 1990-04-17
Abstract: PURPOSE:To accurately control a traveling route by detecting the position of a trackless carrier vehicle by an address signal inherent in a guiding floor tile in the case of covering a floor with a guiding floor tile to form guiding floor and traveling the carrier on the floor. CONSTITUTION:When the trackless carrier is shifted to right, the rotational frequency of a right motor M2 is increased to increase the speed of a right driving wheel 62 and the rotational frequency of a left motor M1 is reduced to reduce the speed of a left driving wheel 61. When the carrier is shifted to the left, a reverse signal is outputted to control the advancing direction. A CPU part 8 stores a traveling program in a memory. At the time of receiving a signal inherent in the guiding floor tile from demodulating circuits 55a, 55b in a tile reader part R, the CPU part 6 decides which guiding floor tile is used for current traveling, compares the current traveling state with a previously stored traveling program, and outputs a control signal to a control part 7 to control the direction change, stop, start, etc., of the carrier. In addition, the CPU 8 measures pulse generated from pulse generators 65a, 65b to measure a very short distance.

Title: Nonaqueous electrolyte for battery and nonaqueous electrolyte battery
Inventor: TAKECHI KENSUKE
IPC: H01M10/0567
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To effectively prevent an evil influence by a halogen acid, and prevent the degradation of a battery, an electrolyte and a battery can material or the like by adding an inactive complex forming compound to a nonaqueous electrolyte containing a support electrolyte capable of generating a halogen acid by reacting with water so as to interact with water and the support electrolyte. SOLUTION: Representative one of a complex forming compound as a compound which is added to a nonaqueous electrolyte and forms an inactive complex by interacting with water and a support electrolyte, is a carbodiimide compound. When there is no carbodiimide compound, a PF6 anion generated by ion dissociation of LiPF6 isolates HF by reacting with water, but when the carbodiimide compound exists, a double bond part of a diimide bond part (-N=C=N-) weakly makes a hydrogen-bond with a water molecule, and since a complex where a PF6 anion electrically bonds to these is formed, HF is not generated. An adding method of the complex forming compound is not particularly limited.

Abstract: PURPOSE:To protect a lead frame against deterioration in electrical properties and to prevent cracks from occurring in a case by a method wherein one or more cuts are provided to an island. CONSTITUTION:For instance, an island 1 is formed larger than a pellet 2 by 0.3-0.4mm in dimensions, and three cuts, 3a-3c, are alternately provided to the opposed long sides, the length of the cuts, 3a-3c, is set 4/5 or so as long as the short side of the island 1, but when the length of the cuts is set as long as possible taking the strength and the processability of a lead frame determined basing on its quality and thickness into consideration, it grows large in effect.
