Filed: 1988-01-20
Abstract: PURPOSE:To raise the water proofness of tunnel by a method in which a supersonic wave vibrator is attached to one or both sides of the coupler parts consisting of a fastener body and sliders and joints are hot-bonded while engaging the coupler parts. CONSTITUTION:Coupler parts 3 and 4 made of a thermoplastic resin are connectedly set on side in the longitudinal direction of blade parts 1 and 2 of a water- proof sheet. The part 3 is provided with couplers 3a-3c and the part 4 is provided with couplers 4a-4c. A supersonic wave vibrator 6 is attached to the peripheral side of the small-diameter portion of the guide plate 5e of a slider 5 serving to engage the parts 3 and 4. The parts 3 and 4 are set in a mutually facing manner, the parts 1 and 2 are fixed, and the parts 3 and 4 are advanced between guide plates 5d and 5g and guide plates 5g and 5e.

Title: Image former
Inventor: INUZUKA TSUNEKI
IPC: G03B27/00
Filed: 1981-01-21
Abstract: PURPOSE:To prevent false fare computation by stopping copying when a key counter is removed. CONSTITUTION:When a key counter CNT 1 is removed prior to turning-on of a copying key, the electric power source to other counters CNTs 2-4 supplied through the counter CNT 1 is turned off and therefore a key counter presence or absence CCNTi goes to the L level, and the removal of the counter is inputted to a control circuit which prohibits the acceptance of the copying key. The electric power source is supplied to paper feed solenoids SL1, SL2, of pickup rollers in the upper and lower steps through the counter. Therefore, when the key counter is removed after the copying cycle has been started by turning the copying key on, the movement of the paper feed solenoids is stopped and normal paper feeding cannot be made. Namely, normal copying cannot be accomplished despite the false use of the key counter.

Abstract: PURPOSE:To obtain a long-life optical information recording element by forming tracking guide zones, distributed at desired pitch and to desired width through transparent material areas with low reflectivity and high magnetic permeability, by oxidizing a recording medium film consisting essentially of chalcogen metal by irradiating it with O ions. CONSTITUTION:Over a transparent disk 1 made of glass, polyimide resin, etc., a recording medium film 2 consisting essentially of chalcogen metal, such as  Te-N and Te-Se, is formed by high-frequency sputtering. The disk 1 is irradiated selectively with an ionization O beam under vacuum to oxidize the film along the circumference of the surface at constant intervals and to constant width, forming transparent material areas 3. The transparent material areas 3 are used as guide zones for tracking. Thus, a smooth recording element having no work groove is obtained. Further, a low-energy semiconductor laser is usable and the life is prolonged remarkably as compared with a recording medium film 2 made of only TE.

Title: Air-fuel ratio controller for engine
Inventor: KISAKA HIROYUKI
IPC: G05B11/36
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in controllability and exhaust emission by determining a predetermined deteriorating condition of exhaust flow rate on the basis of an engine operating condition and suppressing air-fuel feedback control if deterioration of estimation accuracy of an observer is predicted from rapid increase of unnecessary time accompanying reduction of the exhaust flow rate. SOLUTION: From a detection value of an air-fuel ratio detecting means 22, an air-fuel ratio (x) for each cylinder in an engine 1 is estimated by means of an estimating means 30b, and an air-fuel ratio is feedback controlled in each cylinder by means of a regulating mean 16 so that each air-fuel ratio estimation value (x) becomes a target air-fuel ratio. In this process, a basic regulation quantity, which corresponds to the target air-fuel ratio, of the regulating means 16 is set on the basis of an engine operating condition in a basic regulation quantity setting unit 30a, and by means of a feedback correction unit 30c, the basic regulation quantity is corrected so that the air-fuel ratio estimation value (x) for each cylinder becomes the target air-fuel ratio.  If a determining means 30d determines that an exhaust flow rate of the engine 1 is dropped below a predetermined value, correction of the basic regulation quantity is suppressed by means of suppressing means 30e.

Abstract: PURPOSE:To prevent missing in recording by performing the regeneration of records on the recording paper for conversion data which are stored in a dual-port memory at a speed higher than in an ordinary measurement recording during a period wherein the recording paper is in short by using a recording system. CONSTITUTION:In a paper shortage mode, a first microprocessor (MPU) 1 recognizes a detected recording-paper shortage signal which is inputted from a recording-paper detecting circuit 7 and stops the sending of an interruption signal INTRQ2 into a second microprocessor (MPU) 2. The MPU 1 performs only the measurement and display of an analog input signal Ain. The results of the measurements are sequentially stored in a dual-port memory 3. At this time, recording operation is not performed in the MPU 2. Then, in a recovery recording mode, the detected recording-paper shortage signal which is sent into the MPU 1 from the circuit 7 is reversed when the recording paper is supplied. The MPU 1 continuously sends the signal INTRQ2 to the MPU 2 regardless of an ordinary measuring period until the time the regenera tion of the records of the measured data during the period of the recording paper shortage which are stored in the memory 3 is finished and the delay in recording operation is recovered.
