Patent JP-S641580-A (JP)
Title: Recording material
Inventor: MATSUSHITA TOSHIHIKO
IPC: B41M5/155
Filed: 1987-09-01
Abstract: PURPOSE: To enhance the preservability of an image, by forming a color forming system from a usual colorless or light-colored dye precursor and an aromatic isocyanate compound.  
     CONSTITUTION: A color forming system consisting of a usual colorless or light- colored dye precursor and an aromatic isocyanate compound is formed on the same base material or said components are applied to different base materials. When the dye precursor is brought into contact with the aromatic isocyanate compound through external energy, for example, heat, both components are reacted to form a colored reaction product. Since this reaction is irreversible, the reaction product once reacted does not return to the colorless or light-colored dye precursor. As a result, the image composed of the obtained reaction product is excellent in image preservability such as light fastness, plasticizer resistance or the like. As the dye precursor, compounds of a triphenylmethane type, a fluorane type, a diphenylmethane type, a thiazine type, a spiropirane type or the like are designated.

Inventor: KOMINAMI MASAYA
IPC: F02D41/14
Filed: 1985-09-30
Abstract: PURPOSE:To improve control precision of EGR efficiency, by a method wherein the opening of an EGR valve is controlled according to an output from an O2 sensor detecting O2 concentration in suction air mixed with EGR gas, and energization to a heater, heating the O2 sensor, is controlled according to a suction air amount. CONSTITUTION:An EGR valve 10 is located between pipes 11 and 12 through which an exhaust pipe 9 is communicated with a suction pipe 2, and is controlled by an electronic control circuit 14 according to an output from an O2 sensor 6 having a detector 12 for the number of revolutions of an engine, a suction air amount detector 4, and a heater 7 adapted to heat the sensor to an ordinary motion temperature. The O2 sensor 6, heated by the heater 7, is cooled by suction air to decrease temperature when a suction air amount is increased. In which case, in order to prevent decrease of temperature, control is effected so that a power fed to the heater 7 proportionally to an increase in a suction air amount is increased by a heater correcting means 15 to which an output signal from the suction air amount detector 4 is inputted.

Title: Mos type semiconductor storage device
Inventor: HORIUCHI TADAHIKO
IPC: G11C11/41
Filed: 1989-08-25
Abstract: PURPOSE:To reduce power consumption in a memory cell and to improve the speed of a read/write action by setting the threshold of a MOS transistor constituting the memory cell larger than that of a MOS transistor constituting a peripheral equipment. CONSTITUTION:The bias voltage of a second P well 3 in the second N-channel MOS transistor TR 5 constituting the peripheral equipment is 0V. Thus, a drain current increases and the action speed of TR 5 can be improved. In such a case, a sub-threshold current about 10<-10>A flows, for example, even if a gate voltage is 0V. On the other hand, the substrate bias of -3V is impressed on the first P well 2 of a first N-channel MOSTR 4 constituting the memory cell from a substrate bias generation circuit 6 in such a case, and the sub-threshold current of respective TR is set to be less than 10<-12>A. Thus, the power consumption of the memory cell can considerably be reduced and the speed of reading and writing can be improved.

Title: Optical recording tape and its production
Inventor: WATANABE RYUJI
IPC: G11B7/24009
Filed: 1985-10-02
Abstract: PURPOSE:To attain a writing or erasing operation with a smaller quantity of incident energy by using a metal that can vary the spectral reflection factor or an alloy to form a recording layer, and providing an interfering or absorbing layer for incident light energy to he recording layer at the incident side for light energy. CONSTITUTION:A metal or an alloy causes reversibly the phase transformation by the light energy and varies its spectral reflection factor according to said phase transformation. Such a metal or alloy is used to a recording layer 1. An absorbing layer 3 is formed with a material which absorbs the incident energy at the incident energy side of the layer 1. Thus the incident energy is largely absorbed by the layer 3 and changed into the heat energy and the temperture of the layer 3 increases suddenly. Then a colorless and transparent interfering layer 2 of the appropriate thickness is added to the energy input side of the layer 1. The energy reflection factor can be reduced by controlling properly the thickness of the layer 2. Thus the temperature of the layer 1 rises quickly up to a high level compared in a case where no layer 2 is provided. Therefore, it is possible to record the prescribed information by cooling rapidly the recording medium after heating it locally and then holding the crystal structure obtained in a high-temperature area also in a low-temperature area.
