Title: Hydraulic tube expanding device
Inventor: KODAMA TOSHIO
IPC: F28F9/16
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To make the depth of a clevis formed at a joining part between a tube plate and a heat transfer tube as shallow as possible by pressing a mandrel to the tube plate side with a pressing means. SOLUTION: A temporary expanding part 10 is formed on a heat transfer tube 2, a tube plate 1 is temporarily fixed to the end of the heat transfer tube 2 with this. After a mandrel 3 is inserted from a heat transfer tube holding hole to the inside of the heat transfer tube 2 until striking to the tube plate 1 with its flanges 5, hydraulic liquid is injected inside the heat transfer tube 2 sealed with a 1st seat ring 4 and a 2nd seal ring 6 from a hydraulic liquid injection inlet of the mandrel 3, and the hydraulic pressure is supplied inside a pressure adding chamber 11 from a hydraulic pressure supplying tubes 12, 13 communicated to the hydraulic pressure supplying source of a pump, etc.  In such a way, the end part of the heat transfer tube 2 is expanded, the heat transfer tube 2 is adhered closely with the inner circumferential face of the heat transfer tube holding hole and the mandrel 3 is pressed to the tube plate 1 side. In this way, the positional displacement of the mandrel 3 to the falling off direction from the inside of the heat transfer tube 2 is prevented from generating caused by the hydraulic pressure injected inside the heat transfer tube 2.

Title: Automatic error correcting apparatus of direction finder
Inventor: OZAWA MIKIO
IPC: G01S3/64
Filed: 1987-05-07
Abstract: PURPOSE:To make an indicator to agree with the true arriving direction of a radiowave, by applying a signal to a power source for a driving motor when a digital signal from an encoder agrees with the output signal of an A-D converter, and stopping said motor. CONSTITUTION:An A-D converter C sends out a digital signal corresponding to the arriving direction of a radiowave including errors due to antennas in the vicinity, structures or the like. A rotary encoder E is driven with a motor M, and the output of the encoder is sequentially changed. When the signal agrees with the output signal of the converter C, a signal is applied to a power source J, and the rotation of the encoder E is stopped. The encoder E is formed so that the stopped position compensates for the error. Therefore, an indicator A, which is coupled with the motor M, indicates the true arriving direction of the radiowave. A digital display D indicates the direction in digital quantity.

Title: Image data processor
Inventor: HIRANAKA DAISUKE
IPC: H04N19/80
Filed: 1995-04-11
Abstract: PURPOSE: To prevent the generation of a part which is not encoded and is thrown away in a device encoding an image after reducing the image. CONSTITUTION: An image reduction means 1 reduces a sheet of the input image of lateral M picture elements and longitudinal N picture elements by defining lateral X×m picture elements and longitudinal Y×n picture elements as a unit and an image compression encoding means encodes the reduced image by defining the block composed of lateral m picture elements and longitudinal n picture elements as a unit. Namely, the size of the unit reducing the image is made lateral X times and longitudinal Y times (X and Y are integers) as many as the size of the block compressing and encoding the image. When the reduction by a picture element unit is performed like a reduced image (1), a fraction which can not be divided is generated in the block.  Because this fraction part is not encoded, the reduction is performed by defining three lateral blocks and two longitudinal blocks as a unit like a reduced image (2).

IPC: B60R1/06
Filed: 1978-09-11
Abstract: PURPOSE:To prevent the accumulation of errors as well as to return a mirror to the eye-point accurately by detecting the number of revolutions of a motor constantly and comparing the detected value with a set point for controlling a control circuit automatically. CONSTITUTION:When a switch SWA is pushed, circuits 21A and 24 are on for self-holding. When outputs of circuits 21A, 24, and 5 and and-circuit AND 1 are brought into high levels, as the result, a transistor Tr4 is on to rotate a motor M1 regularly. The number of the revolution is detected by a unit 8, and input into a circuit 4 as pulse signals through a circuit 7 and others. A mirror is changed in the angle to the right hand until the count in the circuit 4 is accorded with the set point in a circuit 3. When the output of AND1 is decreased into a low level, a timer circuit 2 is on to keep the static state of the mirror until the set time is over. Then, when the output of AND2 is brought into a hibh level, a transistor Tr7 is on to rotate the motor M1 reversely, and the mirror is returned to the eye-point. When the count value is accorded with the set point, the motor M1 is stopped automatically.

Abstract: PURPOSE:To obtain a DC amplifier very stable against temperature fluctuation by halving a resistance of a load resistor to a resistance of emitter resistor and approaching a bias of 3rd and 4th transistors(TR) to the bias of 1st and 2nd TRs. CONSTITUTION:The resistance of load resistors RL1, RL2 is selected to be a half the resistance of the emitter resistor RE. Then the emitter of the 3rd and 4th TRs Q3, Q4 of the same performance as the 1st and 2nd TRs Q1, Q2 for differential amplifier is connected in series with the collector of the 1st and 2nd TRs Q1, Q2 via the load resistors RL1, RL2 respectively. Simultaneously, the bias of the 3rd and 4th TRs Q3, Q4 is approached to the bias of the 1st and 2nd TRs Q1, Q2. Thus, the output voltage is not affected by a base-emitter voltage VBE of the TR to improve the operation stability and the allowable quantity with respect to the gain change of the absolute value dispersion of the circuit components such as TRs and resistors being components of the amplifier is increased.
