Title: Rotary compressor
Inventor: SAKAMAKI HIROSHI
IPC: F04C18/344
Filed: 1985-03-30
Abstract: PURPOSE:To improve starting property of a rotary compressor by forcing compressed air to directly flow into an air bearing chamber located along the inner periphery of a center housing's compression side, from an operation chamber of the compression side through a gap between a rotary sleeve and housings of both sides. CONSTITUTION:A rotary compressor consists of a rotary sleeve 30 supported with free rotating movement inside a center housing 22, a rotor 10 rotating at an eccentric position inside the rotary sleeve 30, and a vane 16 inserted in the rotor 10 with free sliding movement. With the above consitution, prescribed gaps 30a, 30b are provided respectively between each of both sides of the rotary sleeve 30 and a front and back side housing 21, 23. And compressed air under high pressure is forced to flow in an air bearing chamber 40 along the inner periphery of the center housing (22)'s compression side, through the gaps 30a, 30b. This consequently increases bearing efficiency of the air bearing chamber 40, and prevents a direct contact between the outer periphery of the rotary sleeve 30 and the inner periphery of the center housing 22.

Title: Polyurethane
Inventor: DEBITSUDO UOOSU HAUSU
IPC: C08G18/80
Filed: 1986-03-24
Abstract: Polyurethanes may be conveniently made by curing disocyanate-terminated urethane prepolymers with a N, N'-dialkylmethylenedianiline. The diamine N, N'-di(2-butyl)-4, 4'-methylenedianiline is a particularly useful diamine. The resulting polyurethanes often are thermoplastic rather than thermosetting, making them especially useful as coatings, adhesives, and sealants. Such secondary aromatic diamines have acceptable pot lives and afford products with a variety of properties.

Abstract: PURPOSE:To attain high performance transistor (TR) driving with high efficiency while suppressing heat dissipation by detecting the base current at the primary side of a transformer, and making the current constant and using a saturable transformer inserted to the secondary side to form a reverse bias circuit. CONSTITUTION:The value of a smoothing reactor L1 is selected to include a ripple in a base current in the high frequency switching state where a main TR Q5 cannot respond to, a peak value to the current is detected at the primary side of a transformer T1 to apply on/off control thereby making the secondary current constant. Then with an off-signal, the output terminals of the reactor L1 are short-circuited to bypass the current thereby quickening the leading of the current at the next on-state. While the saturable transformer T2 connected to the secondary side of the transformer T1 is saturated, electric charges are stored in the capacitor C3 to use the stored charge as a reverse bias power supply.

Title: Flip-flop circuit
Inventor: OIDA YOSHIO
IPC: H03K3/012
Filed: 1986-03-25
Abstract: PURPOSE:To increase the maximum operating frequency by connecting a resistor and a peaking circuit in series as a load of a differential pair transistor (TR) so as to cancel the effect of the stray capacitance in existence to the collector of the differential TR. CONSTITUTION:The impedance viewing toward the emitter of a TR Q9 at a prescribed high frequency region is inductive in a circuit comprising the load TR Q9 and resistors RC1, RB1 in an emitter coupling logic FF circuit subject to circuit integration to form a peaking circuit 10 having a characteristic known as the peaking characteristic. Similarly, a load TR Q10, resistors RC2, RB2 form a peaking circuit 11 similarly. Thus, the effect by the stray capacitance existing between collector connecting points N1, N2 and the ground is cancelled. Thus, the frequency characteristic of the FF circuit is improved and the self-running frequency being an indication of the maximum operating frequency is improved remarkably. Even with a clock input exceeding 1MHz, the circuit is operated stably.

Abstract: PURPOSE:To measure stable light phase modulation characteristics modulator into one light path of an interferometer, vibration to one light path with a certain period. CONSTITUTION:While a phase modulator 15 to be measured is inserted into a branched light path 10 of a Mach-Zehnder interferometer 2, a phase modulator 6 is inserted into a light path 11 and then an electrical signal is input from a signal source 17. A coherent light is input from a light source 1 to an input port 8 of the light source 11. A photoelectric converter 4 performs square-law detection of light signal and then averaging it for performing photoelectric conversion. The output signal is amplified by an amplifier 5 and then is output to an output terminal 16. However, in a method for giving vibration, a means 18 for vibrating a light path is provided instead of a phase modulator in the light path 11 and then the output signals of the light paths 10 and 11 are input to the photoelectric converters 3 and 4, respectively, thus outputting differential signals and hence measuring stable phase modulation characteristics with less fluctuation.
