Title: Method for using many times copied or printed sheet
Inventor: YAMAZAKI TOMOKI
IPC: C09D11/328
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To utilize a recycling of a copied or printed sheet by using many times the copied or printed sheet. SOLUTION: Coloring matter dyes of three primary colors which develop colors in alkaline properties and an iodo-starch dye which develops black color are respectively regulated in a chromaticity and a viscosity with solvents. Then, they are set in an ink jet unit. A sheet is color printed by using a printer having the jet unit. When the printed sheet becomes unnecessary, the sheet is sprayed with organic or inorganic acid dilute solution or reducer solution, or coated with it by a roller. Or, it is fumigated by these drugs to simultaneously erase the four colors. After it is dried, the sheet is recycled.

Title: Snowfall sensor
Inventor: IRITANI KOJI
IPC: G01N27/00
Filed: 1993-02-19
Abstract: PURPOSE:To allow easy sensing of snowfall by a constitution wherein a Peltier effect element sandwiched by boards can be switched alternately between an AC power supply and a DC voltage measuring circuit through a switch. CONSTITUTION:A Peltier effect element 1 is heated by Joule heat so long as the element 1 is connected with an AC power supply 3 through a switch 2. Consequently, boards 1e on the opposite sides of the element 1 are heated uniformly when no snow is present on the surface thus producing no temperature difference. When snow is present on the surface of the element 1, the boards are heated by Joule heat and the heat of melting of snow touching the boards causes temperature difference between the surface and rear boards 1e. An electromotive force corresponding to the temperature difference is induced when the element 1 is connected with a DC voltage measuring circuit 4 through the switch 2. In other words, a voltage corresponding to the amount of snowfall is induced in the circuit 4 and snowfall can be sensed by measuring the induced voltage.

Filed: 1992-02-19
Abstract: PURPOSE:To provide a method of a batch growth/process, by which an active layer and current blocking layers are created using selective growths so that uniform optical semiconductor elements excelling in reproducibility are obtained on a wafer of a large area. CONSTITUTION:First, by an MOVPE selective growth, an n-InP clad layer 2, an active layer 3 and a p-InP clad layer 4 are created, and the whole of the active region is covered with a (111) B plane. Thereafter, an SiO2 film 21 is removed partially, and using the effect that the (111) B plane suppresses the speed of the MOVPE selective growth, current blocking layers are made to grow selectively on both the sides of the active region. Thereby, highly uniform optical semiconductor elements on a wafer of a large area are obtained since no semiconductor etching is used. Also, the elements of a high performance can be realized since the current blocking layers are created.

Title: Ultrasonic doppler flow meter
Inventor: SAITOU KOUJI
IPC: G01P5/24
Filed: 1981-03-06
Abstract: PURPOSE:To eliminate the influence of the level fluctuation of a detection signal, by comparing an amplitude average value of the Doppler-shifted detection signal as a reference voltage with the detection signal in the ultrasonic Doppler flow meter. CONSTITUTION:Ultrasonic waves are transferred from an oscillator 3 into a fluid 5 by a signal from an ultrasonic transmitting part 1. Reflection waves due to scattered materials 6 and the transmission signal propagated in the tube wall are received by a receiving oscillator 3', and these reflection waves and the transmission signal generate the beat of a Doppler frequency. The beat signal has Doppler shift components extracted through a high frequency amplifier 7, a detecting circuit 8, a low pass filter 9, and a low frequency amplifier 10. A part of this output becomes a DC voltage corresponding to the magnitude of the received signal through a full-wave rectifying circuit 18 and an average value circuit 19 and is used as a reference voltage of a comparator 20 and is compared with a Doppler signal, and thus, the influence of the fluctuation of the received signal level due to the change of the density of scattered materials, the degradation of the characteristic of oscillators, etc. is eliminated.

Filed: 1984-02-24
Abstract: PURPOSE:To make any trouble informable to a driver at once, by installing a self-diagnostic function which diagnoses non-display and anything unusual due to connection failure and trouble in the cable, in a display unit. CONSTITUTION:When connection failure in a cable 3 between a control circuit 1 and a display circuit 2 or anything trouble inside the display circuit 2 happens there, such a portion that each bit length of a signal S1 out of a shift register 21 and a signal S2 out of a shift register 12 comes into being congruous with each other is produced there. Therefore, a level of an output signal S3 of an Exclusive OR circuit 13 comes to 1, and since an AND condition is effected by the signal S3 and a clock signal CL at an AND circuit 14, a level of a signal S4 out of the AND circuit 14 comes to 1 as well. In consequence, a latch circuit circuit 16 is set and the level of 1 is kept up so that a light emission diode 17 emits light. Therefore, if a car speed indication takes place with a display element 23, it is known as a misindication and, what is more, a fact that it is caused by connection failure in the cable 3 is known as well.

Abstract: PROBLEM TO BE SOLVED: To diagnose a failure at the time of deceleration to prevent a driver from receiving a sense of incongruity by adding a set function of purge ON operation time of a purge valve to a control means based on a detected speed at the time of deceleration. SOLUTION: It is judged whether deceleration is being done or not (step 102). In case of YES, engine speed Ne is compared with diagnosis conducting rotation number No (step 104), and if Ne exceeds No, t1 time for conducting no diagnosis at the time of rapid deceleration is compared with set time Ta after t1 time until fuel cut control conducting rotation number N1 from No is measured (step 106) (step 108). In case of YES, t2 time which is purge ON operation time of a purge valve is determined by t1 time (step 110). After that, suction air pressure change amount absolute value Pevp and judgement level MFevp are compared and judged (step 120). In case of YES, it is diagnosed that an abnormality due to small flow rate in an evapopurge system occurs to inform a driver of the abnormality (step 122).
