Title: Piezoelectric transformer driving circuit and cold cathode-ray tube illuminator using it
Inventor: HORIUCHI YUKITO
IPC: H05B41/24
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a driving transistor by driving a piezoelectric transformer by generating a high voltage on the secondary side of a piezoelectric transformer by switching transistors at every prescribed period which is equal to one turning-on periods of the switching transistors or longer. SOLUTION: The operation of a flip flop 3 is stopped by generating a signal S1 by delaying a lighting stop signal S from a drive stopping circuit 8 by means of a delay circuit 14 and supplying the signal S1 to the flip flop 3. The delay time of the delay circuit 14 is set at the timing after switching transistors Q1 and Q2 are switched one or more times or longer. That is, the flip flop 3 generates pulse signals as Q- and Q-outputs by frequency-dividing a pulse signal to one half upon receiving the pulse signal from a pulse oscillation circuit, turns on the transistors Q1 and Q2, and boost the secondary side voltage of a piezoelectric transformer 6 to a high value by supplying outputs P1 and P2 to the transformer 6.

Title: Metal mold for press brake
Inventor: AKUTSU MITSUO
IPC: B21D5/02
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To obtain a metal mold having durability and to obtain inexpensive products by utilizing the metal mold in possession by spreading a cloth material having stretchability between both sides of a V-groove of a lower mold, thereby preventing the bending flaws generated at the time of bending of a plate material. SOLUTION: The cloth material which has the stretchability and is knitted of liquid crystal polymer fibers having strength of several times that of iron and fibers of a fully aromatic polyester system and aromatic polyamide system of <=530 in denier is preferably spread between both sides of the V-groove. The cloth material 4 is spread between the upper mold 2 and lower mold 1 in possession under use. The cloth material 4 is stopped at several points by means of tapes, etc., to a lower mold 1 or the lower mold mounting base. The plate material to be subjected to bending is put between the upper mold 2 and the cloth material 4 and is subjected to bending. Since the cloth material has the stretchability, the cloth material restores to the home position after bending even if the cloth material is pulled to the V-groove at the time of bending.  The pulling of the cloth tapes fixing the material and the peeling of the cloth material do not occur. The cloth material is merely necessitated to be kept rounded when not used. The repetitive use thereof is thus possible. The cloth material is soft but has the strength several times that of the iron and is, therefore, durable.

The coolant from the double bottom section tube sheet is ventilated to a spot adjacent to the top sheet at the top of the heat exchanger. A second blower 100 which drives the coolant is laid out in a series to the flow of the ventilation of the coolant from a main blower 95.  In such an unexpected stop state, the main blower comes to a stop but the second blower still continues the operation.

Title: Method for generating data cell, data cell generating device and data cell receiver
Inventor: DE VRIENDT JOHAN
IPC: H04L12/70
Filed: 1999-12-15
Abstract: PROBLEM TO BE SOLVED: To drastically increase network efficiency by multiplexing plural data/voice packets to at least one mini cell, adding overhead information representing the length of the data/voice packet and subsequently multiplexing plural mini cells to a data cell. SOLUTION: When a packet multiplexer P-MUX receives three voice packets P1 to P3 with 1st to 3rd input terminals, it determines the lengths of P1 to P3 and notifies an OH-ADD of them through information transmitted on a link between the control output of the P-MUX and the control input of the overhead adder OH-ADD. The P-MUX connects P1 to P3 and supplies the connected packet as a data packet to the OH-ADD. The OH-ADD adds an overhead section OH representing the lengths of P1 to P3 to the data packet. Thus, a headerless mini cell MC1' is generated.

Abstract: PROBLEM TO BE SOLVED: To suppress toner consumption without disturbing an image by simple image processing by selecting and extracting an image pattern, interleaving an image area part at a prescribed ratio, and varying the interleaving method of image data depending on the area of the image pattern. SOLUTION: A bit map memory 50 in a laser beam printer 10 converts image information sent from a host computer 20 in the unit of one dot and gives the converted image into an image processing section 60. The image processing section 60 applies logical calculation to the received image information. First one-dot line length is set and when the length of the image data by one dot in the main scanning direction is longer than a reference length of one dot line in the main scanning direction, whether or not discrimination is repeated for a prescribed number of times in the sub scanning direction is discriminated. When repeated for a prescribed number of times, the image data are sent to an image synthesis section without image processing. Then only the image data meeting the criterion for a prescribed number of times are fed to an interleave processing section.
