Title: Crt drive circuit
Inventor: KOBAYASHI MASAKI
IPC: H04N5/66
Filed: 1994-07-13
Abstract: PURPOSE:To improve raster moire to give priority to focusing by controlling the screen voltage to a specified preferential level. CONSTITUTION:A CPU 10a of a screen voltage control part 10 reads the voltage data out of a storage and gives this voltage to an operational amplifier 4a of a screen voltage generation circuit 4 via a D/A converter 10b. Then the focus of a CRT is kept in its best state with supply of the DC analog voltage. Under such conditions, the presence or absence of the raster moire is confirmed. If the moire is confirmed, the data on the part 10 are changed by a screen voltage changeover switch 9 of the CRT. Thus the screen voltage is dropped down to an optimum level so that the best focus is secured with no raster moire. The DC voltage is controlled by a contrast volume 8a and a brightness volume 8b of a user volume 8 and supplied to a video amplifier 1 and a cut-off control circuit 2 for adjustment of brightness, etc. Thus the raster moire is improved and the priority is given to focusing in response to the display screens.

Title: Heater for heating furnace
Inventor: MATSUO HIDEAKI
IPC: H05B3/62
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To previously remove many faults occurring according to a deformation of a heater by rotatably equipping a heating furnace with the heater as a heating source of a work charged in the furnace, thereby preventing the deformation of the heater. SOLUTION: A rack 73 is mounted at an end of a rod 72 of a cylinder 71 in an upper portion of the heating furnace, and engaged with a gear 33. When the rack 73 is advanced and retreated via the rod 72 by a drive of the cylinder 71, the heater 31 is alternately repeatedly rotated forward and reversely of respective half rotations via the gear 33 engaged with the rack 73. When a steel material of a low temperature is charged in a heat treating chamber of a high temperature correspondingly heated to a predetermined temperature by the heater 31, a heat surface of a side corresponding to a steel material is temporarily quickly cooled, but a heater surface of the side corresponding to a heat insulator disposed at its opposite side is substantially not cooled, and hence the heater 31 is recessed to the material side to tend to be bent according to a difference of thermal contractions.  In this case, the heater is rotated by half, thereby preventing the heater from being bent.
