Title: Heat exchanger
Inventor: OOMORI JIYUNJI
IPC: F28D1/04
Filed: 1978-09-11
Abstract: PURPOSE: To provide heat exchanger capable of reducing thermal stress of cooling pipes and having high reliability.  
     CONSTITUTION: Heat receiving face of cooling pipe 2 is formed in a cone-like configuration which corresponds to energy distribution of high speed particles passing therethrough. Thermal load on the surface of cooling pipe 2 is thereby distributed  uniformly so that no thermal stress due to temperature difference in the londitudinal  direction of cooling pipe 2 is induced. Furthermore, a bellows 9 is formed on a cooling water inlet pipe 8a to absorb thermal expansion by compression of the bellows 9  as well as by a bent portion of the cooling pipe 2. Therefore, arresting force at both  ends of the cooling pipe 2 is decreased, thereby thermal stress being reduced outstandingly.

Title: Part position correction control method and device
Inventor: ONO KATSUHIKO
IPC: H05K13/04
Filed: 1992-04-03
Abstract: PURPOSE:To calculate the quantity of position deviation of a part and perform its correction operation during its movement to an initial target position, and correct the position of the part in a short time by producing a correction quantity against the initial target position on the basis of the quantity of the position deviation of the part, and adding this correction quantity to the intial target position and producing a corrected target position. CONSTITUTION:A nozzle 35 adsorbs a chip part 36, and a camera unit 30 takes an image of the chip part 36. An image processor recognizes the position of the chip part 36, and a calculating means composed of a CPU for example calculates the quantity of the position deviation of the chip part 36. On the basis of this, a correcting target value producing part 4 produces a servo command value denoting a correction quantity against an initial target position. And an adder part 6 adds the servo command value denoting this correction quantity to a servo command value denotiang an initial target position produced by a target value producing part 2, and supplies it to an adder part 8 and a control part 10. Consequently, it becomes possible to correct the position neglecting nearly correction time, and speed up mounting.

Title: Balancer and over spin device
Inventor: OSAWA SUSUMU
IPC: F16C32/04
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a balancer over spin test device to be supported on a magnetic bearing to effect consistently regulation of the balance of a sample and an over spin test by properly compensating for the imbalance of a balancer and over spin device itself containing a magnetic bearing. SOLUTION: An imbalance compensating circuit forms a digital circuit having constitution as shown in Fig. The output deviation (e) of a displacement sensor passes through a filter F(s) to fetch only a rotation synchronous component and further passes a filter -(ATA)<-1> AT using a determined influence factor A. A weight factor may be taken in the filter. An output correction vector increase content WO forms a 0-th correction input vector w0, which is added to a control compensation circuit output signal. A re-correction vector increase content w1 is then computed and a computing result is added to a preceding correction input vector to obtain a first correction input vector W1. As noted above, by repeatedly computing a corrector vector, even when a fixed error is present at the influence factor A, an imbalance is compensated with high precision.

Title: Receiver and reception method
Inventor: HATAKEYAMA IZUMI
IPC: H04L1/00
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To locate the disappeared data at a substitution position in a simple circuit constitution by using a disappearance processing means which converts the information on the received data into a prescribed soft decision symbol and also shows that the information is disappeared by the substitution and then deinterleaving and decoding the disappearance information additional data. SOLUTION: The transmitter side transmits the information which codes and interleaves the symbol of a prescribed position and then substitutes the symbol for the control information. At the receiver side, a disappearance processing circuit 25 converts every symbol other than the control information into a soft decision symbol corresponding to the 14-value soft decision data for the demodulation data D9 obtained via a receiver 12. The circuit 25 also converts the symbol of the control information into a soft decision symbol consisting of 0 to assign it to the disappeared information and generates the 1st disappeared information additional data D26. The data D26 are deinterleaved by a deinterleaver 26 and then Viterbi-decoded by a Viterbi-decoder 27. Thus, a simple circuit constitution is obtained with no use of a conversion table nor an arithmetic circuit.

Title: Image forming method and electrostatic latent image carrier
Inventor: GOTO AKIHIKO
IPC: B41N1/14
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To selectively and uniformly stick ink only to an image part without sticking the ink to a nonimage part at all and to attain an output of printed mater at the same level as that of planographic printing, in a light printing field by simultaneously executing electrification and the imagewise exposure. SOLUTION: In an electrostatic latent image carrier 1, a photosensitive layer and a dielectric layer having nonphotosensitivity and ink repulsiveness are successively laminated on a conductive substrate. In this case, the electrification and the imagewise exposure are simultaneously executed by an electrifier 12 and an exposing device 13, from the side of the dielectric layer of the electrostatic latent image carrier 1. Then, an electrostatic latent image corresponding to the difference in capacitance between exposed and unexposed parts is formed. In the charge-applied part (the part electrified simultaneously with the exposure) of the electrostatic latent image, the surface of the dielectric layer is changed from the ink repulsiveness to ink receptiveness and the ink of the ink carrier 19 of a developing unit 14 butted to the electrostatic latent image carrier 1 is transferred.  The charge quantity of an only electrified part is relatively smaller than that of the charge-applied part, so that the surface of the dielectric layer keeps the ink repulsiveness. Thus, the ink of the ink carrier 19 is not transferred.

Title: If integrated circuit provided with if frequency monitor
Inventor: HAGA HIROSHI
IPC: H04B1/26
Filed: 1994-04-28
Abstract: PURPOSE:To measure the frequency without affecting a reception demodulated signal by providing a buffer amplifier between an input section and a measurement terminal of a discriminator. CONSTITUTION:A monitor buffer amplifier 9 is positioned between an input terminal and a measurement terminal (d) of a discriminator DISC 5. Since a 1st IF frequency of an input signal received from the input terminal (a) is known, a 2nd local oscillation frequency of a 2nd local oscillation circuit 2 is discriminated by measuring the frequency of the buffer amplifier 9. Even when a measurement device is connected to the measurement terminal (d), the effect of the input impedance on a disk drive is small. That is, the effect of an external impedance generated at the frequency measurement is reduce. Thus, the circuit is used to monitor the frequency for automatic frequency control or to detect a low level carrier signal by connecting a detector and a filter to an output of the buffer amplifier 9.

Filed: 1978-09-11
Abstract: PURPOSE:To extend the reproduction lower limit frequency for the speaker by providing the phase inverting mechanism formed by the resonance due to the stiffness between the back air and the air mass caused by the sound path of the pierced hole of the top plate. CONSTITUTION:The extremely light vibrating film 9 to which spiral voice coil 10 is printed is distributed with the tension applied the magnetic gap of the magnetic circuit. Then the linkage is secured between the outside and the airtight space of the back of film 9 enclosed by the magnetic circuit through only pierced hole 6 drilled to top plate 4 forming the magnetic circuit. Here the optimum conditions to be required for the phase inverting mechanism to extend the low range lower limit frequency is as follows: (mass of film 9)=(air mass of hole 6) and (stiffness of film 9)=(stiffness between back space of film 9). And these optimum conditions can be realized most approximately by linking the inside and outside of film 9 only through the sound path of hole 6.
