Title: X-ray soldering inspecting device
Inventor: IGARASHI SHUZO
IPC: H05K3/34
Filed: 1989-08-14
Abstract: PURPOSE:To enable the implementing of a soldering inspection free from effect of the construction of a printed wiring board by performing a subtraction processing between a transmission X ray image signal when no electronic components are mounted on the wiring board and an image signal when they are mounted. CONSTITUTION:A printed wiring board 2 is irradiated with X rays from an X-ray source 4 and an X-ray camera 6 detects a two-dimensional intensity distribution of the X rays transmitted. Then, an image memory 8 stores an image signal from the camera 6 when no electronic components are mounted on the wiring board 2 and a subtractor 10 performs a subtraction of image signals from the camera 6 when the electronic components are mounted on the wiring board 2 synchronizing the image signal stored in the memory 8 and a difference signal is displayed two-dimensionally on display device 12. With such an arrangement, as the wiring board 2 is set at the same position before and after the mounting of the electronic components, background signals based on an internal wire pattern are cancelled, thereby enabling the obtaining of image information on which a decrease alone in transmission of X rays as caused by soldering is reflected.

Title: Crc error generating system
Inventor: NAKAMURA JIYUNKO
IPC: H04L1/24
Filed: 1987-08-21
Abstract: PURPOSE:To check the retransmission function of an error block and to attain error check accurately by providing a memory storing a bit controlling the occurrence/unoccurrence of a data error in a block and causing an error to a designated block so as to check the retransmitted frame. CONSTITUTION:Frame transmission is initiated after '1' is written (intervention by operator) into an address of a memory corresponding to a block desiring to cause an error in a transmission station. In starting the frame transmission, a frame transmission circuit 12 receives a CRC error control bit CB to the transmission frame from a memory 28. The frame transmission circuit 12 forms a CRC normally when the control bit CB is 0 and forms an irregular CRC if the control bit is '1'. A frame reception circuit of a reception station detects a CRC error. In detecting the CRC error, the reception station applies retransmission request from its and succeeding frames to the transmission station and it starts the retransmission processing.

Title: Direct ignition device for gas heater
Inventor: TAKAHASHI KEIJI
IPC: F24C3/10
Filed: 1992-08-04
Abstract: PURPOSE:To prevent soup from being over-boiled and spilled over to an ignition plug and unify the shape of combustion flames and the temperature distribution. CONSTITUTION:The top and the front of an ignition plug are covered with a cover board 10 whose tip is curled. A part of gas ejected from a burner port 2 is engulfed into the tip side 11 and ignited therein. Since the ignition plug 5 is covered with the cover board 10, a spilled-over article is hardly built up on the plug and the gas ejected from the burner port is partially engulfed and ignited there. This construction makes it possible to unify the shape of combustion flames and the temperature distribution as it provides an exclusive designed burner port, thereby preventing the generation of unequal portions.

Title: Fluidized bed heat exchanger
Inventor: ANDOU TOMOAKI
IPC: F28D13/00
Filed: 1983-11-07
Abstract: PURPOSE:To utilize the feature of the fluidized bed efficiently and improve heat transfer performance by a method wherein multiple rows of heat transfer tubes are partitioned into each row by perforated plates and the filling amount of solid particles in each row is limited to the height of the heat transfer tube. CONSTITUTION:The heat transfer tube 8 of each row is contacted thermally with fins 9 arranged in parallel with a given space while the heat transfer tubes 8 are partitioned by the perforated plates 10 serving as a flow stabilizing member in each row. The solid particles 11 are filled into each row to the upper limit height of the fins. Airflow, generated into the direction of arrow sign 12 by a fan, and the solid particles 11, floated and fluidized by the airflow, effect heat exchange between the fluid in the heat transfer tube 8. The solid particles 11 in each row, partitioned by an upper limit perforated plate 15, lower limit perforated plate 14 and the partitioning perforated plate 10, are floated and flowed by the airflow generated by the fan. In this case, the solid particles are floated and flowed only between the upper and lower perforated plates, therefore, the floating flow will never be restricted by the upper tube rows and uniform floating flow condition is shown in each row. Accordingly, the fluidized bed, having constant particle concentration, is formed around the tube in each row and the temperature boundary layer of airflow is broken, therefore, the heat transfer efficiency may be improved remarkably.

CONSTITUTION:The three-dimensional free curved surface from an input device 4 is divided to a picture element for cutting by a free curved surface generating processing system 1 and made into the polyhedron off-set in accordance with the shape of the tool from a free curved surface. Based on the polyhedron, a tool path generating system 2 for cutting a free curved surface calculates the coordinates (X, Y) of the starting end and the trailing end of the cross line of the plane group of a prescribed interval and a polyhedron in parallel to a Z axis and in a Y axis direction. Next, when plural cross lines to belong to the same plane are overlapped concerning X coordinates, the cross line, in which Z coordinates come to be maximum, is selected by the system 2 and tool path data are set as coordinates (X, Y and Z). Thus, the tool interference and non-interference are decided, and tool path data to satisfy a necessary processing accuracy based on the sufficient data quantity are generated at a high speed.

IPC: G06F17/28
Filed: 1989-08-11
Abstract: PURPOSE:To improve the retrieving efficiency of English words by excluding the English words including the non-character codes out of the English words consisting of the character codes only in a word retrieving state. CONSTITUTION:A code check means B adds a code non-character to a specific position of an English word including a code other than the character codes to show this fact at retrieval of English words and decides an English word includes a non-character code or not according to the presence or absence of the code added to the specific position. An English word retrieving means C retrieves the English words except those including the codes other than the character codes that are decided by the means B. Furthermore an English headword context display function 6 is added to display the context right before or after a certain English word in order to show an English word including a code other than the character code. Thus the means B excludes the English words including the non-character codes in a word retrieving state. Then the English word retrieving efficiency is improved.

Title: Distortion compensation circuit
Inventor: IWATSUKI MASANORI
IPC: H03F1/32
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive distortion compensation circuit to compensate the distortion of a power amplifier by providing a detection means which detects the signals of an intermediate frequency band that is branched out at the input side of an amplitude modulation distortion compensation means and then controlling the phase shift value of a phase shifter by means of the output of the detection means to compensate the amplitude phase component. SOLUTION: The voltage (envelope voltage) of 20 to 30 MHz is applied to a 2nd distortion compensation part 542 from a component that is approximate to the DC obtained by a detection circuit 13 and controls the phase shift value of a phase shifter included in the part 542. Thus, the level of the signal which controls the phase shifter of the part 542 can be set completely independent of a 1st distortion compensation part 502 which compensates the AM-AM distortion. Then the optimum gain can be set for an amplifier 12 of an IF band of 70 MHZ, for example, regardless of the type of the AM-AM characteristic, so that the AM-PM distortion can be satisfactorily compensated. Furthermore, the more optimum phase shift control characteristic can be secured via an amplifier 14 which has a nonlinear relation between its input and output levels.
