IPC: F17C13/12
Filed: 1992-08-24
Abstract: PURPOSE:To perform cooling of a liquefied gas container without requiring any large-sized facility and without using external energy substantially. CONSTITUTION:When the temp. of a liquefied gas container 12 attains near the critical point, a temp. sensor 26 senses a temp. signal corresponding to the temp., and an actuation circuit 28 drives an actuator 24 upon judgement that this temp. signal exceeds the set temp. near the critical temp.

Title: Production of waveguide type optical element
Inventor: HIYOSHI YASUO
IPC: G02B6/13
Filed: 1985-11-05
Abstract: PURPOSE:To obtain a waveguide type optical element with a decreased propagation loss by using arsenic sulfide glass as a vapor source or sputtering source and forming a thin chalcogenide glass on a substrate material. CONSTITUTION:As2S3 among various kinds of the chalcogenide glass is particularly good in the optical transmission characteristic in a visible region and near IR region. The arsenic sulfide glass expressed by As2Sx (x=3.1-3.8) is used as a vapor deposition source or sputtering source for obtaining the thin film for the waveguide. The arsenic sulfide glass is obtd. by subjecting a quartz glass tube compounded with a prescribed ratio of high-purity simple substances of arsenic and sulfur to vacuum sealing, then putting the tube in an oscillatable electric oven, resting the tube in the oven at 600-850 deg.C to effect the reaction of the arsenic and sulfur and finally subjecting the same together with the glass tube to quick cooling in water. The thin arsenic sulfide film 3 formed on the substrate 1 is inherently the optical waveguide of a slab type and is, therefore, usable as various kinds of optical elements. The uniform thin film is thereby obtd. and the waveguide type element having the small propagation loss is formed.

Title: Voltage controlled oscillator
Inventor: SAEKI HIROSHI
IPC: H03B5/02
Filed: 1989-09-25
Abstract: PURPOSE:To obtain an oscillation output whose oscillation frequency can be varied linearly by voltage control over a wide range from a low frequency up to a high frequency by adopting the constitution such that the feedback quantity to an active circuit is kept constant irrespective of the oscillating frequency when the oscillating frequency in the resonance circuit varies with the application of a control voltage. CONSTITUTION:When a control voltage is applied to varactor diodes D1, D2 of a resonance circuit 1, the resonance frequency is changed, and an active circuit 3 is oscillated in response to the resonance frequency of the resonance circuit and the oscillating signal is outputted. Moreover, the control voltage is applied to a varactor diode D4 in a capacitance ratio variable circuit 4 and the capacitance ratio between the varactor diode D4 and capacitors C7, C8 is controlled to make the feedback quantity of the active circuit 3 constant independently of the oscillating frequency, thereby controlling the strength of the oscillation. Thus, the relation of the control voltage versus the oscillating frequency is linear over a wide range from a low frequency up to a high frequency without a complicated circuit constitution and the voltage controlled oscillator with less level fluctuation is realized.

Title: Anti-skid mechanism for four wheel drive car
Inventor: ARIKAWA TETSUO
IPC: B60T8/32
Filed: 1983-12-29
Abstract: PURPOSE:To control the brake pressure optimally while independently against the front and rear wheels under four wheel drive, by interrupting a mechanism for coupling driving force intermittently on the basis of a brake pressure control signal thereby releasing integral coupling of front and rear wheels. CONSTITUTION:Upon considerable deceleration of front wheel 6, for example, a control unit 22 will produce a brake release signal on the basis of a detection signal from a wheel speed sensor 15 to function a controller 27 thus to control the brake pressure of front wheel 6. At the same time, the brake release signal is fed to OR gate 39 to bring its output high thus to energize a coil 42 and to open B contact 41. Consequently, an electromagnetic mechanism 44 is de-energized to bring an intermittent system 8 to interrupting position. As a result, the front wheel drive shafts 3, 4 and propeller shaft 7 are decoupled to prevent transmission of variation of the wheel speed of front wheel 6 through front wheel drive shaft 4 and transmission 2 to the rear wheels 12, 13 resulting in independent braking of rear wheels 12, 13 by means of each brake 37, 38.
