Title: Drive circuit for wire dot head
Inventor: FUKANO TAKAKAZU
IPC: B41J2/30
Filed: 1989-07-07
Abstract: PURPOSE:To inhibit the occurrence of an adverse electric current by a method wherein, as a drive circuit for controlling the rising of an electric current passing through a coil, one end of the coil for driving a wire pin is connected to a power source line and the other end thereof is connected to a grounding conductor and an input terminal of a counter electromotive force control circuit. CONSTITUTION:When a switching element 10a is turned ON by a coil drive signal S2, an electric current is passed to a coil 13a through a path of Vp, 13a, 10a, and GND. Just before the completion of this time, a counter electromotive force control signal S3 is made to rise to turn ON a counter electromotive force control circuit 14. At the completion of the aforesaid time, the element 10a is turned OFF, and only the circuit 14 remains ON. Then, an electric current is passed through a path of 13a, 12a, 14, Vp, and 13a by the counter electromotive force of the coil 13a to be effectively used as a part of a drive current for the coil 13a. Moreover, when the element 10a and the circuit 14 are simultaneously turned OFF, an electric current is passed to the coil 13a for a short time by a counter electromotive force. The element 10a is again turned ON, but the circuit 14 remains OFF for a while to avoid an adverse electric current.

Title: Core molding method
Inventor: SAKOTA MASARU
IPC: B22C9/10
Filed: 1986-07-25
Abstract: PURPOSE:To obtain a core having plural layers consisting of different kinds of molding sands with good accuracy with small-sized equipment by detaching 1st and 2nd metallic molds to a prescribed distance to form a fresh cavity in the mating parts of the two molds, packing the molding sand of a different kind in superposition on the layer preliminarily formed at every formation of the cavity and curing the sand. CONSTITUTION:The cavity having the approximately specified thickness is formed in the mating part of the two metallic molds 1, 2 when said molds are closed. The molding sand for the 1st layer is blown into the cavity and the molding sand is cured by heating the molds 1, 2 to form the hollow 1st layer A1. The molds 1, 2 which are held closed are then moved to the position below a 2nd blow tank 4 and the tank 4 is lowered to clamp the 2nd mold 2. The tank 4 is raised to detach the 2nd mold 2 from the 1st mold 1 by the prescribed distance and to form the fresh cavity between the 1st layer A1 and the 2nd mold 2. The sand a2 for the 2nd layer in the tank 4 is blown through a blow head 6 into such cavity. The molds 1, 2 are heated similarly so that the 2nd layer A2 is formed in superposition on the 1st layer A1.

Title: Data processing circuit
Inventor: TAKANO HIDETO
IPC: G06F3/06
Filed: 1991-07-17
Abstract: PURPOSE:To deal with the speedup of the revolving speed of a CD driving device by the central processing unit of the same throughput in the data processing circuit of CD-ROM by detecting the completion of the transfer of one sector by the number of transferred data by using a counter, and detecting a synchronizing pattern at a forefront of the next sector. CONSTITUTION:Every time the data of one byte is outputted from the CD driving device 6 to a buffer memory 2, an address generator 4 increases an address of outputs by '1', and the counter 8 counts the number of the transferred bytes. When the counter 8 detects the number of the bytes of one sector, it stops output to the buffer memory 2, and simultaneously, it informs the central processing unit of this. While the central processing unit 3 executes processing to set the address for outputting the next sector to the buffer memory 2, the synchronizing pattern is sent from the CD driving device 6. When a synchronism detection circuit 1 detects this synchronizing pattern, the output of the data of the next sector to the buffer memory 2 is started.

Title: Contacting material for sewage cleaning and its manufacture
Inventor: TAKAHASHI MASANORI
IPC: C02F3/10
Filed: 1990-07-04
Abstract: PURPOSE:To manufacture a contacting material with high corrosion resistance efficiently at a low cost by putting a large number of coil contacting threads made of non- thermosetting-type resin on a core material of a thermosetting-type resin, twisting the resulting body, and heating it to fix the core material in the twisted condition. CONSTITUTION:A tape-like woven fabric is prepared using fibers of a thermosetting resin and a large number of coil-like contacting threads 2 made of nonthermosetting resin are put on the upper face of it. When the resulting body is put in a bath at about 70-80 deg.C while twisted either rightward or leftward, the contacting threads 2 are extended like a flower-in-water with coil shape. With twisted, the tape-like body 1 becomes a core material 4 and at the same time is hardened by heating to have toughness and thus a contacting material having coil-like contacting threads 2 and suitable for microbe adhesion and propagation is composed. Or while twisted, the tape-like woven fabric 1 on which the contacting threads 2 are put is coiled on a cylinder 5 and by treatment e.g. passing the resulting body in hot water bath, an ideal spiral contacting material which does not return to the original strip body and has high toughness is obtained.
