Title: Optical synchronization terminal station equipment
Inventor: NISHI KIYOTAKA
IPC: H04B10/079
Filed: 1992-06-08
Abstract: PURPOSE:To implement a conducting test of a transmission line even when there is out of clock synchronism between a sender side equipment and a receiver side equipment. CONSTITUTION:An output signal 13 and a test signal 12 of a transmission processing section 7 for an STM signal are inputted to a selection section 8 in a transmitter side equipment 1, and the selection section 8 selects the test signal 12 by means of a test start signal 14 outputted at the time of test and transmits the selected test signal 12 to an optical transmission line 5. A test signal discrimination section 9 of a receiver side equipment 3 identifies and receives the test signal 12. Since the test signal 12 does not flow through the transmission processing section 7 together with a reception processing section 10, the transmission line is tested independently of the synchronization of the station clock.

Title: Printer device
Inventor: TAKADA TAKASHI
IPC: G06F3/12
Filed: 1989-06-07
Abstract: PURPOSE:To reprint data after stopping halfway to print data by storing several- page components of data in a data buffer so that this data can be used again and controlling the printing of this data by a printing control part. CONSTITUTION:A data buffer part 3 takes in input data 11 inputted from the external by the number of pages indicated by an input page select signal 15. A printing part 4 sends an error signal 19 to a command selector part 2 if printing is impossible because of the end of paper, paper jamming, running-out of ink, or the like. When an error signal 19 or a stop request from a data transmission side 1 or an operation panel 5 of a printer main body comes to the command selector part 2, a stop command signal 18 is transmitted to the printing part 4 to stop printing after an output select signal 16 is saved in a register 6. When a reprinting request comes from the data transmission side 1 or the operation panel 5 of the printer main body, an output page select signal 6 saved in the register 6 is transmitted to the data buffer part 3. Thus, reprinting is possible.

Title: Method for forming concrete with high physical properties
Inventor: SHIBATA TOKUHITO
IPC: C04B28/02
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To conspicuously improve physical properties of concrete, such as strength, waterproofness, and life, by rapidly mixing powder containing a high water-absorptive resin as a main component from below ready mixed-concrete when the concrete is placed. SOLUTION: Equivalently mixed power containing a high water-absorptive resin, silica fume, and a powder waterproof agent is dispersed on a placement surface where bars are arranged, of a floor, a roof, or the like, and ready mixed-concrete is pumped up to be placed on the powder in a usual manner. At this time, the mixed powder is mixed into the concrete from a lower surface of the same. The high water-absorptive resin mixed thereinto from below absorbs surplus water content from a lower portion of the concrete, and therefore movement of the surplus water content in an attempt to upward escape is not generated, whereby a water channel therefore is not formed. Thus, physical properties such as strength, waterproofness, and life, of the concrete are conspicuously increased while using the same ready mixed-concrete material and the same placing system as conventional ones, and breathing is eliminated, whereby leveling is carried out earlier and workability is enhanced.

Title: Delay circuit
Inventor: KOYADA HIROSHI
IPC: H03K5/13
Filed: 1984-07-16
Abstract: PURPOSE:To form a delay circuit made effective even with use of a few cells by connecting a PMOSFET and an NMOSFET in series in a CMOS master slice system LSI. CONSTITUTION:In bringing an input 1 to L level, an output level of an inverter 3 goes to H. An FET5 is sufficiently in on-state in this case and a voltage at a terminal (b) is equal to a power supply voltage. The level at the terminal (b) of an FET6 is at H, then the input of an inverter 4 goes to a level lower than the power supply voltage. In bringing the level of the input 1 to H level, the input of the inverter 4 goes similarly to a level (a level higher than 0V) equal to that of the terminal (b). As a result, the input level of the inverter 4 is always between the power supply voltage and 0V. Thus, the inverter 4 is not sufficiently driven, the speed to transmit an output signal of the inverter 4 to the next stage slows down and a delay circuit is realized. Then the effective delay circuit is formed with a few cells.
