Title: Scroll type compressor
Inventor: NAKAMURA MASAYA
IPC: F04C18/02
Filed: 1993-09-09
Abstract: PURPOSE:To surely prevent the damage of a movable spiral body or a fixed spiral body even in the case where the long term operation of a scroll type compressor is continued under the conditions of high speed rotation and high compression ratio as the large sizing of a shell diameter is restrained to the minimum. CONSTITUTION:The periphery of a movable side plate 41 is protrusively provided with a main guide section 41b striding over a normal L2 at the most external contact point S1 between the inner wall of a movable spiral body 42 and the outside wall of a fixed spiral body 23 at a relative phase where the volume of a central compression chamber becomes substantially zero in a direction perpendicular to an axis O, and a shell section 22 is provided with a main guide face 22a to guide the main guide section 41b only in the direction perpendicular to the axis O. Since the main guide section 41b is guided only in the direction perpendicular to the axis O by the main guide face 22a, even in the case where a gap exists in bearings to bear a movable scroll under the conditions of high speed rotation and high compression ratio, thrust force caused by the above gap is received by the main guide section 41b and the main guide face 22a. In addition, a part of the periphery of the movable side plate 41 is protrusively provided with the main guide section 41b, and the shell section 22 is provided with the main guide face 22a to guide the main guide section 41b.

Title: Gas rate sensor
Inventor: KATSUNO YASUATSU
IPC: G01P5/12
Filed: 1986-09-25
Abstract: PURPOSE:To purely lead the temperature of hot wires as a voltage and to perform accurate detection by providing electrodes for power supply, the hot wires, output signal electrodes, etc. CONSTITUTION:Constant currents are supplied from a power source PS to the hot wires 7a and 7b. Then, the respective output signal electrodes 20a-20d are connected to high impedance type operational amplifiers Q1 and Q2, so flowing currents are fine and the influence of the fusing of the electrodes 20a-20d of the electrodes 6a-6d for power supply is exerted. Further, even if resistance temperature coefficients and heat generation become unbalanced owing to the fusion variance among the electrodes 6a-6d for power supply, output signals are led out of the electrodes 20a-20d while by-passing the electrodes 6a-6d of generation sources. The power source PS, on the other hand, outputs the temperature of the wires 7a and 7b as the voltage, so the stable and accurate output signal is obtained without varying in zero point owing to variation due to the fusion of the wires 7a and 7b.

Abstract: PROBLEM TO BE SOLVED: To easily and accurately detect danger bulging at early time so as to be able to prevent the accident, etc., caused by the bulging from occurring by accurately detecting the fine bulging between rolls in a continuous casting equipment. SOLUTION: A displacement on the upper surface of a cast slab between the rolls, a displacement on the upper surface of the roll near the upper surface of this cast slab and a displacement in a frame of this roll, are measured with three laser sensors 1a, 1b, 1c arranged in a pinch roll zone, etc., of the continuous casting equipment. Then, a true bulging quantity δ' between the rolls is obtd. by subtracting the displacement measured value on the upper surface of the roll and the displacement measured value of the frame from the displacement measured value on the upper surface of the cast slab. When this bulging quantity between the rolls exceeds any one of criterion for judging calculated from an equation showing the relation between the pre-obtd. bulging quantity between the rolls and a cast slab width, casting speed or carbon content in the cast slab, it is judged as the danger bulging, and then, the bulging quantity is restrained by changing the casting condition.

Filed: 1985-10-09
Abstract: PURPOSE:To facilitate reading of information recorded at high density by irradiating parallel light beams on the surface of a recording medium, separating an irradiation route from the parallel beams reflected from the surface of the recording medium and then forming an image on a photodetector by means of a convergence lens. CONSTITUTION:Diffused beams 18, which have expansion and are emitted out of a light source 11 such as an LED and semiconductor laser whose light emitting point is placed at the focus distance of a collimate lens 12, is made incident on the collimate lens 12, and is emitted being parallel light beams 19. Some of them transmits a beam splitter 15. The diameter of the parallel light beams is limited by an aperture 17, and the beams are vertically irradiated on the surface of the recording medium in a mirror face-like state. The irradiated light beams are reflected on the surface of the recording medium to be a scattered light with a strong directivity, most of which pass through the aperture 17 again and reach the beam splitter 15. Furthermore some of the reaching beams is reflected by the beam splitter 15, is made incident on the convergence lens 13, turns out to be a convergence light beam and forms an image on the photodetector 16. Thus information recorded at high density on the surface of the flat recording medium such as a card can be easily read.

Title: Sense amplifier circuit
Inventor: HOSHI KATSUSHI
IPC: G11C11/34
Filed: 1986-09-22
Abstract: PURPOSE:To attain the operation by low current consumption by providing a couple of transistors (TRs) using a node corresponding to a bit line pair as a gate input so as to select a refresh circuit. CONSTITUTION:When a refresh signal phiRF goes from a low level to a high level, a node N5 goes to a high level because a TR T11 using a node N1 corresponding to a bit line as a gate input is activated. On the other hand, a node N6 keeps a low level when a TR T12 using a node N2 corresponding to a bit line as a gate input is not activated. In this case, the node N3 goes to a high level higher by a threshold voltage of a TR than the power voltage VCC via a capacitor C1 whose one end is connected to the node N5 and the node N1 is precharged up to the VCC level by using a TR T13 using the node N3 as a gate input. Thus, the TRs T11, T12 are provided in this way, a sense amplifier circuit based on the information of the nodes N1, N2 being bit lines is selected and the operating current of the refresh circuit not requiring refresh is reduced.

Filed: 1987-09-09
Abstract: PURPOSE:To display gradation close to gradation obtained by (N+1)-bit of picture data while reducing the circuit scale by increasing/decreasing a reference voltage of an N-bit A/D converter by a special value for each period T being an integral multiple of the field period of a picture signal. CONSTITUTION:Both terminals of series resistor circuit (r1-r8) are connected to reference voltage sources VH, VL. Then a gate circuit 101 is connected to the resistor r8 and a gate circuit 102 is connected to the resistor r1 in parallel. Connecting potentials V-, V1-V8, V+ of the resistors r1-r8 are given to one terminal of a comparator 103 as reference voltages and a picture signal VD is inputted to a plus terminal of the comparator 103. With a frame signal F at '1', since the resistor r1 is short-circuited, the voltages V-,V+ are expressed as shown in equation I and with the frame signal F at '0', since the resistor r8 is shortcircuited, the voltages V-, V+ are expressed as shown in equation 11. Thus, since the picture signal is identified into 15 stages of digital values in one frame period, the gradation display close to a 4-bit picture data signal, regardless of 3-bit picture signal, is attained.

Abstract: PURPOSE:To easily recognize all changed data by comparing the time stamp set to each data file with the time information corresponding to the retrieving time range and extracting the relevant data file when the time stamp value is larger than the time information. CONSTITUTION:An input processing part 1 selects a data item to be outputted and reads the designation of the retrieving range time, etc., for generation of an output request file F.
