Title: X-ray generator
Inventor: TSUKAMOTO KATSUMI
IPC: H01J35/06
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To facilitate this adjusting work by automatically adjusting the direction of an electron gun so that an electron beam accurately collides with a target position of an anticathode. SOLUTION: An electron beam (e) emitted from an electron gun 1 is converged by an electromagnetic lens 3, and is collided with an anticathode 4, and X-rays are generated from a surface of the anticathode 4. In such an X-ray generator, an electron beam detecting member 5 is arranged to detect a colliding position of the electron beam (e) to the anticathode 4. Dislocation between a target position of the electron beam (e) to the anticathode 4 and the colliding position is found by a comparing circuit 7 on the basis of a detecting result of the electron beam detecting member 5, and the direction of the electron gun 1 is changed by a driving circuit 8, and the positional dislocation is corrected.

Title: Casting method of high manganese cast steel product
Inventor: SUZUKI NISAKU
IPC: B22C1/02
Filed: 1983-09-12
Abstract: PURPOSE:To obtain a high manganese cast steel which has excellent quality and with which a defect such as burn-on is hardly admitted on the surface by using a casting mold composed of silica sand, coating an MgO or Cr2O3 mold coating material into film and subjecting the steel to vacuum casting. CONSTITUTION:MgO and Cr2O3 both exhibit basicity. The reaction between MgO and SiO2 of silica sand prevents the burn-on of a casting surface. The Cr2O3 mold coating material does not react with MnO as said material has basicity at a high temp. A high manganese cast steel having a good casting surface is thus obtd. Therefore if vacuum casting is performed after the mold coating material of MgO or Cr2O3 alone or a mixture composed thereof is coated into film, the high manganese cast steel product having no burn-on defect formed on the surface is obtd. and the cost by using the molding sand composed of silica sand is reduced.

Title: Communication mode switching device
Inventor: KUROE TOSHIKO
IPC: H04N1/32
Filed: 1987-07-03
Abstract: PURPOSE:To enable switching a connection mode from an origination side to a termination side by sending out an enciphering mode switching request signal and switching the mode automatically when information showing that the current connection mode of the termination side is an undesirable mode is received. CONSTITUTION:When an opposite station originates and an incoming call detection circuit 2 confirms incoming, a control part 10 makes a connection between A and C through a switching circuit 7. At this time, when the termination side is facsimile mode, that is reported through a mode information sending circuit 4. When the origination side requests for a telephone call mode, a code consisting of three predetermined numeric digits is inputted as a mode switching request signal, so a connection between A and D is made and a code discriminating circuit 5 checks its validity, when the code is normal, the origination side is informed of switching to the telephone call mode and then a connection between A and F is made. If a signal other than the normal code is inputted three times, a connection between A and B is made and the line is disconnected on the termination side. Switching from the telephone call mode to facsimile mode is performed under nearly the same operation control.

Inventor: HINO HIROBUMI
IPC: H05G1/32
Filed: 1984-08-13
Abstract: PURPOSE:To improve rising characteristic and response characteristic of bulb voltage waveform and realize high speed repetition of irradiation of X-ray by stabilizing a high DC voltage which has been boosted by a high voltage transformer and full-wave rectified to a predetermined voltage with a chopper. CONSTITUTION:When an X-ray irradiation signal is input, a controller 11 outputs the ON signal of semiconductor switching elements 6, 7 corresponding to an output signal of a comparator 35 and thereby the capacitors 8, 9 are charged and irradiation of X-ray starts. When a bulb voltage during irradiation of X-ray comes closer to a preset value, an output signal of a detector 34 also comes closer to a bulb voltage setting signal and an output of the comparator 35 outputs a signal which makes small power application coefficient. When a bulb voltage becomes equal to a preset value, the elements 6, 7 start switching operation with the power application coefficient at that time. In this structure, when a bulb voltage becomes smaller than a preset value due to fluctuation of voltage to be applied to the capacitors 4, 5, the power application coefficient becomes large and it can be controlled to become equal to a preset value. Thereby, stable bulb voltage waveform can be obtained.
