Inventor: OHIRA MICHIO
IPC: A61L2/20
Filed: 1991-07-26
Abstract: PURPOSE:To perform short-time treatment using low concn. ozone by a method wherein the injection of ozone due to an ozone injection means is started at the point of time when the humidity in a drying chamber raises to a definite value and continuously or intermittently continued until reaching a state held to constant humidity through a high humidity state. CONSTITUTION:In an article drying treatment process using a hot air supply means 3, the humidity (b) in a drying chamber is measured by a humidity detector. The injection of ozone by an ozone injection means 4 is started at the point of time when the humidity (b) in the drying chamber raises to definite humidity and continuously or intermittently continued during a period when the definite humidity is kept through a high humidity state, that is, during a high humidity period W3. Therefore, the sterilizing effect generated by the decomposition reaction of ozone and the forming reaction of a hydroxy radical is developed to the max. The unreacted residual ozone in the drying chamber is entirely decomposed at the time of the completion of drying treatment or forcibly purified in the gas discharge part of the hot air supply means 3 to be discharged.

Title: Electronic control fuel injection device
Inventor: YAKUWA MASAHIKO
IPC: F02D41/00
Filed: 1986-09-08
Abstract: PURPOSE:To open a fuel injection valve at all times neither too much nor too less, by constituting a counter on one side so as not to be operated unless operation of a counter on the other is finished and the specified time elapses, even if such a signal that operates the other side during operation of either of the synchronous counter or the asynchronous counter is generated. CONSTITUTION:When an asynchronous signal is generated during operation of a synchronous signal, this signal is inputted into an asynchronous counter 15 at the point that counting of the specified time by a timer 211 is finished after completion of operation of a synchronous counter 14. Therefore, a pulse out of the asynchronous counter 15 is inputted into a fuel injection valve after output of the synchronous counter 14 falls down at completion of its operation and comes to a low level. Accordingly, supposing main injection time data are set to T1+DELTAT (T1 is desired main injection time and DELTAT shows correction time) and increment injection time data are set to T2+DELTAT (T2 shows desired increment injection time) respectively, total valve opening time of the fuel injection valve actually conducive to the fuel supply comes to T1+T2, so that fuel is not sprayed excessively as much as a portion for DELTAT as in the conventional technique.

Abstract: PROBLEM TO BE SOLVED: To prevent abnormal mesh between a driven gear and a pinion and the occurrence of abnormal sound due to it by a simple structure by providing a positioning means which determines a position of the pinion on a base member between the pinion which meshes with the driven gear and the base member fixed on a door panel. SOLUTION: A pinion 31 of a motor unit 30 is put in a recessed part 12a of a fixed base 12, and the motor unit 30 is fixed temporarily on a flange 12b by using a fixing screw 32. A positioning pin 40 is inserted into a positioning hole 33 formed in the fixed base 12 and a shaft hole 31a of the pinion 31, and a position of the pinion 31 is set on the fixed base 12 accurately to fix it finally by using the fixing screw 32.

Title: A/d conversion circuit
Inventor: OE SHINICHI
IPC: H03M1/52
Filed: 1989-08-14
Abstract: PURPOSE:To decrease the time required for A/D conversion and to speed up the A/D conversion by adding an adder/subtractor, an input terminal and plural switches to a conventional A/D conversion circuit, and controlling the switch so that a difference between the input and a reference voltage is charged, and also discharged. CONSTITUTION:When an input voltage is larger than a reference voltage, switches 9, 10, 13 are turned on and switches 8, 11, 12 are turned off to discharge. When the output of an amplifier 1 crosses a GND level, it is judged by a comparator 2, resulting that a counter 6 is stopped. On the other hard, the most significant bit is '1' when the input voltage is larger than the reference voltage and '0' when the input voltage is smaller than the reverence voltage. When the input voltage is smaller than the reference voltage, the switches 8, 11, 13 are turned on and the switches 9, 10, 12 are turned off, and A/D conversion is similarly applied. Thus, the conversion speed is twice that of a conventional A/D converter, and the resistance and capacitance are reduced in value.

Title: Optical fiber terminal and optical connector with low reflection and manufacture of optical fiber terminal with low reflection
Inventor: NAGASE AKIRA
IPC: G02B6/00
Filed: 1990-08-10
Abstract: PURPOSE:To make reflected return light extremely small in quantity when the tilt angle of an end surface to an optical fiber axis is made small and to reduce the size and cost of an optical component by using an optical fiber which is increased in core diameter in the end surface. CONSTITUTION:The optical fiber 1 has a core-diameter increased part which is increased locally in core diameter is an optical fiber terminal which is cut at the core-diameter increased part 1C and the end surface 3 is ground slantingly to a surface crossing the optical fiber axis at right angles. Each fiber terminal is increased in core diameter, so the tilt angle theta of its end surface 3 to the surface crossing the optical fiber axis at right angles may be small. Further, the ratio of the deviation of the optical axis in the gap of a ferrule 2 from the optical fiber axis is small and the connection loss is reduced. Consequently, the reflected return light from the fiber end surface 3 when an optical element and an optical fiber 1 are connected or when optical fibers 1 are connected mutually is made small and the complexity of assembling operation is evaded.

Abstract: PURPOSE:To reduce the scale of circuit by connecting a switching element and a resonance capacitor in parallel with the primary of a source transformer, then detecting the primary output voltage of the source transformer and controlling the inductance of a saturable reactor transformer and the oscillation frequency of a drive circuit thereby atabilizing the output voltage. CONSTITUTION:A secondary winding NB and a capacitor 6 are brought into series resonance by a voltage induced through the resonance current flowing through the primary winding NR of a saturable reactor transformer, thus turning a transistor(Tr) 9 ON, OFF. When the switching Tr 9 is turned ON, voltage is applied from terminal 1 onto the primary winding N1 of a source transformer 5 while when the switching Tr 9 is turned OFF, voltage resonance is produced through the leakage inductance of the primary winding N1 and a resonance capacitor 7. Then the inductance of secondary winding N2 is controlled through current control of a control winding Nc and the output voltage is maintained constant through control of switching frequency. By such arrangement, the scale of the circuit can be reduced.
