Title: Automatic delay correction circuit for loop form data transmission system
Inventor: USUKI SHIGERU
Filed: 1986-07-11
Abstract: PURPOSE:To avoid system-down even if a data delay in a transmission line reaches 1-frame time or over by activating a delay switching circuit based on a control signal of a discrimination control means and sending data delayed by a corresponding delay quantity in a loop transmission line. CONSTITUTION:When a signal delayed by one-frame time by a storage circuit 29 is received, a storage circuit 30 retards the data by further one frame time and sends a signal delayed by 2 frame times to a switching circuit 28. A delay quantity detection circuit 25 converts an output signal 24 from a transmission timing control circuit 18 into a pulse signal depending on the delay of the output signal 23 from a reception timing control circuit 16 and sends the converted bit pulse to a delay bit counter circuit 26. The circuit 26 counts the pulse signal from the detection circuit 25 and sends its output to a comparator circuit 27. A delay switching circuit 28 is activated based on the signal of the comparator circuit 27 and sends the data of the corresponding delay.

Title: Electronic time piece
Inventor: WATANABE ISATO
IPC: H02P8/02
Filed: 1981-10-15
Abstract: PURPOSE:To overcome the possibility of a judgement that a pulse motor does not rotate despite the rotation of a rotor by returning the normal drive pulses to the minimum width whenever auxiliary drive pulses for driving the pulse motor are generated by a fixed frequency. CONSTITUTION:When it is detected 7 that a pulse motor 6 does not rotate, auxiliary drive pulses are generated from a generation circuit 4 to drive the motor 6 and after that, normal drive pulses with a larger width are generated from the circuit 4. If auxiliary pulses are generated continuously by a fixed frequency because of a judgement that the pulse motor 6 does not rotate despite the fact that it is rotating by the normal drive pulses, outputs are produced from a counter 9 to reset a control circuit 8 whereby the normal drive pulses are returned to the minimum width.

Title: Floor nozzle for vacuum cleaner
Inventor: YAMAURA IZUMI
IPC: A47L9/00
Filed: 1993-07-02
Abstract: PURPOSE:To prevent the heat generation of the motor by exposing one end of the outer shell of the motor on a suction room side to remove heat from the outer shell of the motor by the current of air caused by suction. CONSTITUTION:An outer shell 45 of a motor 29 is exposed on a sucking room 26 from a bulkhead 44 which is formed between a sucking room 26 and a motor housing room 43. Thus the heat is removed from the outer shell 45 of the motor by the current of air caused by suction. The heat of the motor 29 is moved to the exposed outer shell 45 by the thermal conduction. Accordingly, the heat generation of the motor 29 is continuously cooled down when the vacuum cleaner is used. In short, it is unnecessary to install an independent motor housing room 43 and filters preventing dusts on grids set on the side of the sucking room 26 and on the outside of a floor nozzle 21. This is effective not only to reduce the cost due to eliminating the filter but also to reduce the man hour. Further, the depth of the floor nozzle main body 21 can be reduced by placing the motor 29 close to the sucking room 26 and the compact floor nozzle 21 can be used more easily.

Abstract: PURPOSE:To prevent sticking of liquid crystals of the outside walls of a cell on account of capillarity during injection of the liquid crystals by preventing the formation of any gap between upper and lower panels on the outer side of a sealant layer in the part of an injection port. CONSTITUTION:There are gap materials 2 for the purpose of assuring an adequate spacing and a sealant 4 for the purpose of adhering the plastic substrates to each other and sealing a liquid cryatal 3 between a pair of plastic film substrates 1 having transparent conductive films. These are so cut or worked that in the part of the injection port of a cell the layer 4 arrives at the outside circumference of the upper and lower substrates 1 and that in other parts the outside circumferences of the substrates are formed on the side outer than the outside circumference of the sealant layer. It is much better to form the part of the injection port of the cell in such a way that the layer 4 on the side face projects slightly from the substrates 1 to improve the preventive effect against capillarity.

Abstract: PURPOSE:To prevent a fatal damage to the data processing of a receiving side even when a synchronizing signal is omitted by successively adding plural synchronizing signals having different bit patterns to each block in prescribed order and discriminating omission of the synchronizing signals in accordance with the added order on the receiving side. CONSTITUTION:A switch 21 repeatedly selects four synchronizing signals S having difference bit patterns and supplies the signals S to a synchronizing signal adding circuit 12 in prescribed order, for example, in the order of P1, P2, P3 and P4.

An address generation circuit 24 does not output any address designating data to a block B to which the synchronizing signals S are omitted. Therefore, no fatal damage is given to a time base transforming process and interleave operation.
