Title: Crystal vacuum gauge
Inventor: TAMURA FUJIO
IPC: G01L21/22
Filed: 1988-06-13
Abstract: PURPOSE:To measure pressure from low one to ordinary one with one temperature sensitive crystal resonator by utilizing the temperature sensitive crystal resonator as a heat conductive type pressure sensor in a low pressure area and utilizing it as a viscous pressure sensor in a middle pressure to ordinary pressure area. CONSTITUTION:A heat source 8 is set near the temperature sensitive crystal resonator 1 having a negative temperature coefficient. Negative feedback is performed to a power supplied to the heat source 8 so that the frequency of said resonator 1 is kept constant. The oscillation frequency of said resonator 1 is converted into a voltage in a rectifier 9 and added to the voltage supplied to the heat source 8 in an adder 10. According to an output voltage from the adder 10, a meter 11 is driven and the voltage value can be known from the needle of the meter 11.

Title: Cold-pilger mill pipe making method
Inventor: KADOKAWA MASAHIRO
IPC: B21B21/00
Filed: 1985-07-01
Abstract: PURPOSE:To increase the quality by obtaining a good cross sectional shape with less pointing of a pipe and by increasing the effect of the correction for complete roundness as well by subjecting a blank to rolling by its rotation by a limited angle on each material feeding. CONSTITUTION:The rolling is performed with the blank rotation angle on each one stroke of the rolling at 65-85 deg.. In case of the rotary angle being in the above range the elliptic quantity is small and besides the cross sectional shape as well becomes good close to a circular shape although some pentagonal shape remain. The reason why is because of the side relief to prevent a size being formed on the caliber 3 of a roll 4 and the space formed by the upper and lower calibers 3, 3 being not round. And the material 2is intermittently rolled in the rolling zone with the axial direction feeding and rotation being given on each one stroke and becomes in a polygonal shape. And the pipe after rolling is subjected to a rotary straightener to correct its bend and made round completely.

Title: Method and apparatus for reproducing digital signal
Inventor: KAWAMAE OSAMU
IPC: G11B20/18
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To transmit data with higher reliability by switching between the execution and non-execution of repeated correction in an error correction processing depending on a transmission speed of a reproduction signal. SOLUTION: A reproduction digital signal from a disc 1 is decoded 13 to be stored into a memory 14. A memory data is read out into an error correction means 16. A block address for switching an error correction processing and for correction are set for a repetition mode setting means 19 from a system control means 62 in the setting of a repeated correction mode. At this point, the correction processing controls the address of a data to be read in for the generation of a timing signal corresponding to a correction method and the correction processing by a correction switching signal 20. A block address setting signal 10 specifies a block address of a correction data. In the repeated correction of errors, a control is performed to set the same block address. When an output data of an output processing means 17 is insufficient, a mode is set to omit the repeated correction.

Filed: 1985-07-04
Abstract: PURPOSE:To facilitate the variation of the discharge capacity by using the constant capacity type pumps in the number selected so that the unit discharge quantity is in a specific relation to the number of units.

Title: Photosensor array
Inventor: OKABE KAZUYA
IPC: H04N5/335
Filed: 1987-06-11
Abstract: PURPOSE:To improve the yield in manufacture of photosensor arrays, by composing each photosensor of two photosensor elements connected in series such that a transparent electrode layer of one of the photosensor elements is in contact with a metallic electrode layer of the other. CONSTITUTION:In a photosensor array 7, two adjacent photosensor elements 9, 9 are combined such that a transparent electrode layer 4 of one of the photosensor elements 9 is in contact with a metallic electrode layer 2 of the other photosensor element 9 and these two photosensor elements are connected in series to provide a photosensor 8. According to such construction, it is very rare that both of the photosensor elements 9, 9 constituting the photosensor 8 become defective when the photosensor array 7 is manufactured. Even if one of the photosensor elements 9 becomes defective by pin holes in an amorphous Si layer 3 for example, the other photosensor element 9 will operate normally. Further, since photoelectric current is not affected by voltages, no variance is caused in photoelectric characteristics of the photosensor array. Thus, the fraction defective caused by pin holes in the a-Si layer 3 or the like can be minimized and the yield of the photosensor arrays 7 can be improved.

IPC: F01K13/02
Filed: 1983-08-10
Abstract: PURPOSE:To perform rational denitrating control, by a method wherein a flow rate of a reducing material being injected is controlled at each turbine system so that a deviation between a desired value and a detected value corresponding thereto is brought to zero. CONSTITUTION:A deviation signal (g) represents a deviation between a desired value at each turbine system and an actual value, and is inputted as a desired value signal for a flow rate of the injected reducing material to a subtractor 18 through a PI computer 15 and an upper limit value 16. An output signal (i) from a second detector 17 is inputted as an actual signal for a flow rate of the injected reducing material to the subtractor 18. From the two signals, the subtractor 18 computes a deviation between a desired value and an actual value, and a deviation signal (j) thereof is inputted to a PI computer 19. A flow rate of a reducing material, injected to each denitrating device through a regulator 20 for a flow rate of the injected reducing material, is controlled so that a deviation is brought to zero by means of an output signal (k) from the PI computer 19. Addition of a total amount control function to an individual control system enables the other control systems to compensate each other for the one control system which is happened to be forced into a condition in which it is deviated out of a control range.

Abstract: PURPOSE:To obtain the spectrum of the pure phosphorescence component of a phosphor which is not so long in half-reduction period easily and accurately, by intermitting exciting energy for making a measured material to luminesce, by making use of characteristics of the phosphor. CONSTITUTION:Luminous-body sample 1 to be measured emits light with a fluorescence component and phosphorescent component superposed by lamp driving output (a) of exciting lamp driving part 21 while exciting lamp 2 comes on, and consequently the output of amplifier 12 is held at a high level. Once exciting lamp 2 goes off, the fluorescence component disappears while an afterimage of only the phosphorescence component remains, so that output (b) of amplifier 12 will decrease in level. This signal (b) is sent to sample circuit 23. By timing output (c) outputted fixed time after exciting lamp 2 goes off, this circuit 23 holds the level of amplifier output (b) at that time and this held output (d) is sent to pen driver circuit 13. In this way, the spectrum of the pure phosphorescence component can be obtained easily and accurately.

IPC: F24F5/00
Filed: 1991-06-19
Abstract: PURPOSE:To improve the efficiency of a freezing cycle, to reduce the size of an electric part, and to form a product in a compact state by a method wherein the electric part is brought into contact with a part of a heat-exchanger on the outdoor side to conduct the heat from the electric part to the heat-exchanger. CONSTITUTION:During heating operation, a refrigerant flows as shown by a solid line, heat is emitted by a heat-exchanger 5 on the indoor side, and heat is sucked by a heat-exchanger 3 on the outdoor side to effect heating. Since heat generated from an electric part 6 being a frequency converting device is brought into contact with the heat-exchanger 3 on the outdoor side, heat is derived in a freezing cycle to produce a high-efficient freezing cycle. Meanwhile, during cooling operation, a refrigerant flows as shown by a dotted line, heat is emitted by the heat-exchanger 3 on the outdoor side, and heat is sucked by the heat-exchanger 5 on the indoor side to cool the indoor side. In which case, since the electric part 6 is brought into contact with a condenser but the electric part 6 is brought into a state that its temperature is increased to a value higher than that of the freezing cycle, the heat of the electric part 6 is transferred to the condenser and heat is emitted by the heat-exchanger 3 on the outdoor side.
