Inventor: UMEZAKI TATSUYA
IPC: G01R31/28
Filed: 1993-12-28
Abstract: PURPOSE:To reduce the overhead of a circuit and, at the same time, to shorten the time required for preparing a test pattern by judging the observability and controllability of flip flops in the circuit through forward operation and backward operation without back track and selecting FFs to be scanned. CONSTITUTION:A partial scanning system only converts flip flops requiring controllability and observability into flip flops to be scanned in such a way that, after dividing an LSI into combinational circuits A-D respectively surrounded by primary input terminals t1-t5, primary output terminals t6-t8, and flip flops FF1-FF6, a test pattern is prepared against each combinational circuit and the test pattern of the whole circuit is prepared by performing forward operation and backward operation without back track against each prepared test pattern. At the same time, the controllability and observability of faults in a circuit are judged against each flip flop.

Title: Radio communication system
Inventor: MORIFUJI TOSHIAKI
IPC: H03M13/27
Filed: 1993-12-28
Abstract: PURPOSE:To allow the receiver side to make relevant decoding even when a transmitter side varies an interleave size by decoding a frame with the interleave size in a shortest hamming distance for received frames. CONSTITUTION:A receiver side receives one frame of interleaved data by a transmitter side. An address control section 3 reads data received from a memory 2 as to each interleave size under the control of a size dependent hamming distance calculation section 4 of an automatic discrimination section 1 to calculate a hamming distance corresponding to each size. The calculation section 4 makes decoding including data error correction from the memory 2 based on a designated interleave size and compares the decoded data with the read data. Then a bit number (hamming distance) different from bits is outputted to an interleave size discrimination section 5. The discrimination section 5 discriminates the minimum interleave size and outputs the result to a decoding section 6 before end of one frame and the data are read from the memory 6a according to the size and the read data are decoded.

Title: One touch slim nozzle ti for electric vacuum cleaner
Inventor: SUZUKI KOUKI
IPC: A47L5/30
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To facilitate cleaning even at a narrow place such as the rear part of furniture or the like located beside a wall by turning a horizontal (T-shaped) suction port at an extended nozzle tip of an electric vacuum cleaner to be changed for a vertical type (I-shaped). SOLUTION: In this tip suction nozzle, a horizontal type (Tshaped) suction port at an extended nozzle tip of an electric vacuum cleaner is turned to be changed for a vertical type (I-shape) suction port. Traditionally, the tip part of the electric vacuum cleaner is shaped in T (horizontal type) and at a place such as clearance, shaded area or the like, the nozzle at the tip part must be often changed or removed inconveniently before cleaning. Thus, a rotary part 2 is mounted on the normal horizontal type (T-shaped) nozzle body 1 and is turned to be changed for a vertical type (I-shaped) on use. With such a structure, convenient application is possible even at a narrow place, a clearance, a shaded area or the like.

IPC: H04B17/391
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To improve test efficiency by acquiring test results in real time. SOLUTION: An receiver 14 measures a receiving electric field strength of a radio wave transmitted from a mobile station 11 and transmits an actual measurement value to a display unit 16 through an interface 17. Simultaneously, the receiver 14 transmits location data of the mobile station 11 to a computer 15 through the interface 17. The computer 15 calculates distance between a base station 13 and the mobile station 11 in real time based upon the input location data and inputs the distance to an electric field strength theoretic value-calculation program, calculates a theoretic value of the received electric field strength, and transmits the theoretic value to the display unit 16 in synchronization with transmission of actual value of the receiver 14 through an interface 18.  The display unit 16 displays both the actual value from the receiver 14 and the theoretic value from the computer 15, in correspondence mutually with time function.

Title: Bs tuner
Inventor: HIRASHIMA MASAYOSHI
IPC: H04N7/167
Filed: 1990-11-30
Abstract: PURPOSE:To automatically switch to other receivable channel in the case the broadcast is changed to a chargeable broadcast in the midway of viewing by detecting a state of a specific bit of a control code in a sound signal for showing a fact that it is a chargeable broadcast, varying a tuning frequency by using its detecting output, and tuning it to an unchargeable channel. CONSTITUTION:When a chargeable broadcast is started after a prescribed time (arbitrary length) elapses, and a specific bit Y of a control code in a sound signal becomes '1', phi6 is outputted from a control code detecting circuit 11. As a results a 2-channel rise signal phi8 is transmitted to a remote control signal processing circuit 3 through a NOR gate 19. Accordingly, a tuning frequency of a frequency conversion/tuning processing circuit 1 is further shifted to the upper channel by two channels. In such a way, while a normal satellite television broadcast signal is being received, its channel is received continuously, and when the specific bit Y becomes '1', it is switched automatically to other channel, therefore, it is extremely convenient to a viewer.
