Patent JP-H0924509-A (JP)
Title: Manufacture of tile
Inventor: SAKAKIBARA YOSHIYUKI
IPC: B28B3/02
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To prevent the density of a molding from becoming uneven and thereby, manufacture a tile of specified size and shape at a rate of high yield in the dry molding of the tile. SOLUTION: First, a projecting part is provided at a spot other than the edge of one side (the end of the movement of a powder measure) in which the filling density of a body is low. On the other hand, recessed parts 4a, 4b are formed at spots other than the edge of one side of the rear surface of a molding. Besides, the spots are thinner than the other side (the end of the movement of a powder measure) in which the filling density of the body is high). The overall eve part of the molding is almost of the same thickness. Alternatively, the upper surface of the lower die and the lower surface of a punch are slanted forming a gradient to the other side. Consequently, it is possible to obtain a molding with an even density without causing a problem of thickness difference.  Thus a finished product of desired size and shape can be manufactured at a rate of high yield by preventing the incorrect size, improper shape and cracking due to a shrinkage difference at the time of baking from occurring.

Title: High sensitivity camera
Inventor: SAKAMOTO MINORU
IPC: H04N5/243
Filed: 1992-06-10
Abstract: PURPOSE:To pick up a dark picture even by using a conventional image pickup device by providing a delay circuit delaying a video signal by one frame and an adder adding the output signal of the image pickup device and the output signal of the delay circuit to the camera. CONSTITUTION:A video signal picked up by a video camera 1 is converted into a digital signal by an A/D converter 2. Then the signal is delayed by one frame at a delay circuit 3 and the delayed signal is fed to an adder circuit 4 and the output signal of the A/D converter 2 not delayed is fed to other terminal of the circuit 4. Consequently, in-phase input signals are fed to the circuit 4 and they are added by the adder circuit 4, from which a video signal whose amplitude is doubled is obtained. When the signal is converted into an analog signal by a D/A converter circuit and sent, a video signal with a large amplitude is obtained as an output signal and a picture with high contrast is obtained. Then the number of 1-frame delay circuits is increased and video signals of several frames are added to attain high sensitivity.

Title: Semiconductor laser driving equipment
Inventor: TAKEUCHI MAKOTO
IPC: B41J2/44
Filed: 1994-07-27
Abstract: PURPOSE:To improve the pulse width reproducibility of an image signal, by turning a semiconductor laser on independently of the input of the image signal, on the basis of a forced lighting signal, and forbiddening the turning-on of the semiconductor laser while a light amount control signal at a specified level is inputted. CONSTITUTION:Outside a printing region 31, a light amount control signal 11 is turned off and made a mask signal for an image signal 10. Thereby light emission of an LD 6 is prevented when an image controller 5 turns the image signal 10 on outside the printing region. As the preliminary operation before printing operation, a motor and optical system containing the semiconductor laser are driven. A sequence controller 3 turns a forced lighting signal 12 on, and the LD 6 emits light independently of the input of the image signal. Then the controller 3 confirms the operation of optical system containing the LD6. When the forced lighting signal is turned on, the light amount control signal 11 must be set at a specified value. By reducing the processing load of the sequence controller 3 like the above, an excellent picture image of high resolution can be formed at a high speed.
