Title: Fiber optical terminal assembly
Inventor: NIGERU CHIYAARUZU SUMISU
IPC: G02B6/04
Filed: 1990-05-30
Abstract: PURPOSE: To expand the maximum quantity of light transmittable inside an assembly by locally heating an end face, letting glass flow through a bundle of fibers and forming a base to be fused with a housing. CONSTITUTION: A bundle 7 of optical fibers 8 is inserted through a funnel-shaped channel 6 into a sleeve 2. Afterwards, when separating a jig 5, the cross section of the sleeve 2 is filled with the fibers 8 in tightly filled structure. An end face 11 trimmed at a front end 10 of the sleeve 2 is locally heated, a recessed face 11a is formed on a tray-shaped glass surface layer 14, and a zone 15 of fused fibers composed of the fiber bundle is formed under the surface layer 14. Thus, since required heating is minimized and heating is applied at a position away from non-fused fibers, the fragility of adjacent non-fused fibers is minimized.

Title: Exposing method
Inventor: NISHI TAKECHIKA
IPC: G03F7/20
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To enhance the resolution furthermore while satisfying the requirements for the margin of the depth of focus without shortening the wavelength of illumination light for exposure. SOLUTION: Under presence of an illumination light IL from a light source 1, the pattern image of a reticle R is projected through a projection optical system PL onto a wafer W. The reticle R and the wafer W are scanned in synchronism with the projection optical system PL and exposed. In order to satisfy the requirements for the margin of the depth of focus that the sum of the focus control accuracy, the level difference of an underlying pattern (level difference of a mark), and a width obtained by multiplying a photoresist by a predetermined coefficient is smaller than the depth of focus even when the numerical aperture of the projection optical system is increased, the photoresist is made thin.  Since the target value of accumulated exposure must be varied depending on fluctuation in the thickness of the photoresist when the photoresist is made thin, a resist thickness measuring unit 46 measures the thickness of the resist and controls the accumulated exposure based on the measurement.

Title: Image forming device
Inventor: HIRASHIMA YASUHITO
IPC: G03G15/16
Filed: 1992-06-02
Abstract: PURPOSE:To prevent toner from adhering to a transferring roller, whether the polarity of the toner is positive or negative, by making an electric circuit from the surface of a photo conductive layer to a base substance a nearly insulating state other than a time when a transferring bias is impressed on the transferring roller. CONSTITUTION:The toner 8 discharged form a developing device 6 is electrostatically charged, it is considered to be equivalent to charge, and a current flows when the toner moves. The toner can not move when the circuit of the current at the time is broken. Since the time when the image carrier 1 is brought into contact with a certain surface of the transferring roller 9 is normally about 0.1 seconds, the integral value of the current flowing in limited time becomes small so that the movement of the toner or the amount of that may be limited by making the flow of the current difficult. Normally, the transfer roller 9 is connected with a bias power source grounded, and the conductive base substance 2 of the image carrier 1 is also grounded. The toner is prevented from adhering to the roller by insulating the transferring roller 9 against a ground plane other than the time when transferring is performed, or performing grounding with a value which is equal to or above a specified electric resistance value (for example, 10<5>OMEGA) at such a time.

Filed: 1979-10-31
Abstract: PURPOSE: To obtain the reference signal for comparison with good S/N, by changing the tuning frequency of a tuning circuit according to the frequency of input signal.  
     CONSTITUTION: An input signal D in  is fed to an automatic tuning circuit 63 via a differentiating circuit 61, rectifying circuit 62. The tuning frequency of a circuit 63 is changed with a signal CV in response to playback tape speed. The output of the circuit 63 is fed to a phase comparison circuit 68 via a delay circuit 66. The output of the circuit 68 is fed to an LPF56, and an oscillator 54 is controlled with a voltage adding 69 the phase error output and the signal CV. Thus, the oscillator 54 oscillates at a center frequency even if the tape speed is other than the speed for normal playback, allowing to prevent narrower capture range. A phase comparator 70 changes the delay amount of the circuit 66 so that the phase difference between the input signal D in  and the output of the oscillator 54 can be constant, allowing to prevent the shift in phase difference by tape speed.

Filed: 1984-07-09
Abstract: PURPOSE:To prevent drop of sealing ability at high temperature by sealing an alkaline battery with a gasket comprising polysulfone resin and a sealing layer formed by sealant prepared by dissolving asphalt in nonpolar cyclic hydrocarbon solvent. CONSTITUTION:A sealing part between an outer can 3 and a sealing can 4 of a sealed battery using alkaline electrolyte is sealed with a gasket 1 comprising polysulfone resin and a sealing layer 2 formed by sealant prepared by dissolving asphalt in nonpolar cyclic hydrocarbon solvent such as decalin or cyclohexane.

Title: Electric rotating machine
Inventor: YOSHINO YUTAKA
IPC: H02K3/28
Filed: 1990-05-31
Abstract: PURPOSE:To suppress maximum differential voltage to be generated in one winding and to facilitate automatic insertion of winding into a slot by a method wherein the winding is split into a plurality of winding sections which are then connected electrically in series and arranged while being spaced by a predetermined distance. CONSTITUTION:Maximum differential voltage  V to be generated in one winding can be expressed by  V=V. But since one winding is split, in this case, into upper and lower windings insulated from each other through a separator 12 and an insulating paper 13 and they do not cross each other, maximum differential voltages  V0 and  V1 in the lower and upper windings may be considered individually. Since the upper and lower windings have number of turns equal to half that of each phase winding,  V0= V= V/2 is satisfied and the maximum differential voltage to be generated in one winding can be halved as compared with conventional case. Furthermore, the process for inserting each winding into a slot 2 comprises only six steps and thereby it can be automated easily.

Abstract: PURPOSE: To soften the shock at the gear changing by a method wherein detecting means for the position of a shift lever switch and the suction negative pressure are employed in order to select the duration of half clutch in accordance with various conditions of gear changing operation.  
     CONSTITUTION: When the accelerator pedal is not operated after the gear changing, an accelerating signal (b) is at low level and a high level signal is applied from inverter 45 to a resistor 46 so that a reference voltage generating circuit 49 outputs a signal (b") to a comparator 50. On the other hand, a gear changing signal (a) turns from low level to high level in order to gradually raise the output signal (d) from a charging circuit 44. As a result, the time position, at which the both signals (b") and (d) are in equal level, is retarded and the time for the output signal (e) of the comparator 50 to turn from low level to high level becomes long. The time lag is determined by the output of pulse wave and becomes long enough to generate the duration of half clutch suitable for the conditin of gear changing operation.
