Title: Device in clean room
Inventor: YAGI KATSUTO
IPC: F24F7/06
Filed: 1987-02-20
Abstract: PURPOSE:To be able to keep sufficient cleanliness on working surfaces and reduce plant cost and maintenance cost by placing a primary zone which is parallel to side walls and a secondary zone of which height size is smaller than that of the primary one and supplying uniformly clean air passing through highly efficient filters from blow-off holes at the upper part of the secondary zone. CONSTITUTION:A secondary zone 12a where an apparatus 9 for a manufacturing line is placed and a primary zone 12b where worker pass are placed in parallel to side walls 20 in a space 12 and a clean air supply means is installed between clean air blow-off holes 101 for the secondary zone and a ceiling 19. The height of air blow-off holes at the zone 12b or a passage part is made high to such an extent as to enable workers to pass through on their feet and the height of air blow-off holes at the secondary zone 12b or working place part is made low so long as a hindrance does not occur. After air discharged from a blower 23 is purified by a highly efficient primary filter 25, it is blown off from the holes 101. By this constitution a clean air area and an area for air conditioning are substantially reduced and therefore, plant cost is able to be reduced.

IPC: H02P8/20
Filed: 1980-03-19
Abstract: PURPOSE:To change closkwise and counter-clockwise directions easily by a method wherein an initial value is inputted to the output ports of a register, a motor is turned only by one step every time the phase is shifted and a fixed phase is replaced with another phase when the motor is turned in the reverse direction. CONSTITUTION:An initial value set to a register 21, the shift direction thereof is controlled by means of a shift control circuit 22, is transmitted to output ports, and ports 0, 2 drive a stepping motor 20 through drivers 23, 25 and ports 1, 3 through drivers 24, 26 through circuits 27, 28 exchanging mutual output. The motor is turned in the clockwise direction by delivering '1' signals to an inversion signal terminal 35, and an A phase and a B phase among the output of the output ports are converted by forwarding '0' signals and the motor is turned in the counter- clockwise direction. Thus, the clockwise and counter-clockwise directions can be changed extremely easily without requiring other external circuits.

Title: Hybrid integrated circuit device
Inventor: KANEKO MASAO
IPC: H05K1/18
Filed: 1995-02-23
Abstract: PURPOSE: To mount a high element on a printed board by bending a metallic substrate in a U-shape and forming hollowed-out sections on the mounting surface of the substrate for separately mounting elements. CONSTITUTION: A metallic substrate 3 is bent in a U-shape and mounted on a printed board 2 in a π-structure. Namely, the substrate 3 is composed of three faces of a left side face 13, right side face 14, and top face 15. Through holes P..., P... are formed in two rows through the printed board 2 for inserting outer leads 8 and chip capacitors and elements are arranged between the two rows. It is also possible to mount elements on the outside of the π-structure. Since the substrate 3 is made of a metal, however, it is difficult to get the contact between the elements mounted on the outside of the π-structure and the inside of the structure in the through holes. Therefore, when hollowed-out sections 16 are formed on the mounting surface of the substrate 3 to electrically connect wires to each other in the sections 16, IC mounting sockets or ICs can be mounted on the outside of the π-structure also.

Patent JP-S61195036-A (JP)
Title: Data transmission system
Inventor: TAKEUCHI MOTOHIRO
IPC: G06F13/00
Filed: 1985-02-25
Abstract: PURPOSE:To prevent securely data from being mixed by comparing data of a data input line with that of the data output line of a terminal whenever one bit is outputted during at least one byte outputting period and stopping the output of data when a difference can be found. CONSTITUTION:When two units of terminals supervise a host RXD input line in order to output data, there is the timing when terminals T2 and T3, for instance, output simultaneously data, recognizing that the time of the same one byte is in the MARK state. In such a case at least initial one byte of the data output of each terminal shows an equipment number inherent to each terminal as a number or character, and during the output data of an RXD line is compared with that of the TXD output line of the terminal itself whenever one bit is outputted. When a difference is found, the output of data is stopped. Therefore the terminal T2, which outputs the signal of SPACE at the bit where the difference is found, continues its outputting as it is. Then the terminal T3 outputting the signal of MARK stops its outputting, thereby preventing the data from being mixed.
