Title: Pattern similarity calculation system
Inventor: KANEUCHI KUNIYASU
IPC: G10L15/32
Filed: 1987-12-15
Abstract: PURPOSE: To decrease the total arithmetic quantity by performing collation with only a register which does not collate by preliminary operation and finding the similarities of all registers in consideration of the result of the preliminary operation when the similarities of narrowed down candidates are operated. CONSTITUTION: An input voice is stored in a register 4 as couples of data after a frequency analysis is taken by a BPF 2. Then the similarity is found through AND operation between the most significant digit byte 6a of a dictionary pattern and the input pattern of the register 4 and stored in a register 7. This similarity is put in the register 7 in the order of the collation, word names or word numbers included in a higher half of word names are extracted, and parts which are not preliminarily operated among matching dictionary patterns are taken out and ANDed with the pattern in the register 4 to find the similarity. The pattern of the highest similarity is outputted as a recognition result. Consequently, objects to be collated are narrowed down through the simple operation to reduce the total operation quantity.

Filed: 1987-12-15
Abstract: PURPOSE:To detect both the start point of time and the end point of time of a burst signal stably with excellent response by detecting individually the start point of time and the end point of time of a burst signal so as to detect the period of the burst signal. CONSTITUTION:An input signal is compared with a threshold level Vth1 by a comparator 1, waveform-shaped and supplied to a signal start point time detecting circuit 2 and a signal end point time detecting circuit 3. The signal start point time detecting circuit 2 detects a 1st bit of the burst signal fed from the comparator 1. The signal end point time detecting circuit 3 detects the end of the burst signal fed from the comparator 1 and consists of a comparator comparing an output of, e.g., a low pass filter with a prescribed threshold level. A packet detecting circuit 4 consists of a component such as an OR gate and outputs a signal representing the period (packet) of the burst signal from an output terminal OUT. Thus, both the start point of time and the end point of time of a burst signal is detected stably with excellent response.

Title: Heating method for in-pipe content
Inventor: HIRAYAMA KOTARO
IPC: H05B6/10
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To quickly and sufficiently heat a stored material or a flowing material in pipes by forming the pipes into a pipe group comprising plural number of small diameter pipes arranged in parallel closed-circuitlikely not to get conductive each other, and by engaging an induction coil inclusively to it. SOLUTION: One induction coil 2 is engaged to a group of small diameter pipes 1 to be induction-heated, and induced current circulating around the respective pipes 1 is induced to generate Joule heat ranging a whole circumference of the respective pipes. The pipes 1 are formed into a pipe group comprising plural small diameter pipes arranged in parallel not to get conductive closed- circuitlikely by contacting each other. When conductive closed-circuitlikely, difference is generated between current flowing in an outer part of a contact point and current flowing in an inner part of the contact point so that heating does not get uniform in the circumferential direction, that's a reason why the pipes 1 are made not to be conductive closed-circuitlikely.  The small diameter pipes 1 are separated each other to be nonconductive between the pipes, and alternatively the pipes 1 are arranged closely via an insulating material.

Filed: 1994-12-21
Abstract: PURPOSE: To obtain a bright and easy-to-see screen immadiately after a back light is turned on by making the adjustment quantity of brightness change in accordance with a measured lighting time. CONSTITUTION: When a back light 2 is turned on to display information to liquid crystal display elements 1, the measuring of the lighting time is started in a lighting time measuring means 23. Since a flourescent tube has not been in a thermal equilibrium state right after the lighting of the back light 2 and is dark, the adjustment quantity of a brightness adjusting means 22 is made to be changed by a brightness control means 24 so that a display part 12 becomes brighter than a set state previously set. Then, since the flourescent tube approaches to the thermal equilibrium state as the lighting time of the back light 2 increases, the adjustment quantity of the brightness adjusting means 22 is made to be changed by the brightness control means 24 so that the display part 12 returns to the set state. Thus, the screen becomes easy-to-see and the operability of a device is improved.

Abstract: PURPOSE:To make the output voltage of an integration circuit at input clock stop the same as a voltage in an operation by providing a clock shut-down circuit fixing an output to an H level at input clock interruption. CONSTITUTION:An input clock is inputted to a phase comparator 3 via a clock shut-down circuit 5 fixing an output to an H level at input clock interruption.

Thus, the output voltage of an integration circuit 4 remains before the input clock stop and the phase of the output clock of a voltage controlled oscillator 1 is unchanged even with the stop of the input clock. Thus, the output clock is kept to the state before the stop when the input clock is stopped.

Title: Address generating device
Inventor: KIMURA TAKESHI
IPC: H04K1/06
Filed: 1989-12-11
Abstract: PURPOSE:To generate the addresses at a high speed by turning a pseudo random address that receives the sequential conversion to the combination of element states obtained by a counter block via plural sets of circuit clocks into an output address via an inverse conversion circuit. CONSTITUTION:The character conversion blocks 1-3 are cascaded in plural stages for conversion a sequential address into a pseudo random address. The components that undergo the character conversion processing via the blocks 1-3 of each stage can be set independently of each other among the stages. In addition, such a component that applies the character conversion processing in plural times can also be used together with such a component that applies no character conversion processing at all. Thus a pseudo random address (y) is obtained for expression of a vector. The address (y) is converted again into a pseudo random address (y) for scalar expression via a vector expression adverse conversion circuit 13 and then outputted. This address (y) is used as a transfer destination address which is used for exchange of the scanning line sequence, etc.
