Title: Sliding vane type compressor
Inventor: HASEGAKI TAKAHIRO
IPC: F04C18/344
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of vane chattering phenomena and defective compression phenomena, which take place when an engine is started in a state that there exists the difference in pressure between a high pressure side and a low pressure side in a sliding vane type compressor. SOLUTION: The provision of a gas opening/closing means composed of two gas feeding passages 51a and 51b where one has a large cross sectional area and the other has a small cross sectional area, in the inside of a gas feeding passage communicating the portions of high pressure fluid with one another except a vane back pressure chamber and the oil basin of a high pressure chamber, thereby allows the occurrence of vane chattering phenomena and defective compression phenomena to be avoided by letting at least the passage 51a small in cross sectional area out of the aforesaid two gas feeding passages, be made to communicates with the back parts of vanes, even when the compressor is started regardless of the difference in pressure between a high pressure side and a low pressure side after the compressor has been suspended.

Title: Data processing system
Inventor: MAEKAWA TSUTOMU
IPC: G06F13/12
Filed: 1990-10-25
Abstract: PURPOSE:To enhance the efficiency of system by reading out data for mn times (m>=2) of transfer obtained by combining data for n times of transfer required by a central processing unit (CPU) and their adjacent data from a main storage in a burst mode and processing the read data. CONSTITUTION:Requested data for n times of transfer are transferred to the CPU 10 and residual adjacent data for n times of transfer are stored in a buffer means 31 and their addresses are stored in an address storing means 32. When the CPU 10 requests data for the succeeding n times of transfer, the addresses of the data are compared with the addresses stored in the means 32, and when both the addresses coincide with each other, the data stored in the means 31 are transferred to the CPU 10. When the addresses are different, data are read out from the main storage device 20. Thereby, when accesses from the CPU 10 are continued, the total access time to the main storage device 20 can be shortened and a bus occupation time can be shortened only by a period corre sponding to the transfer of the adjacent data. Consequently, the efficiency of the data processing system can be enhanced.

Title: Training signal detector
Inventor: TAKAHASHI FUTOSHI
IPC: H04B1/76
Filed: 1989-11-09
Abstract: PURPOSE:To surely decide a MODEM adjustment start timing without making the hardware of the MODEM complicate by detecting a prescribed repetitive patterns segment based on the quantity of extraction of a baud timing outputted from a timing extraction section. CONSTITUTION:A timing extraction section 30 acts like a timing extraction section for a reception side MODEM and is shared for a part of a timing extraction control section for various processing synchronously with a reception signal. A counter 20 is counted up or reset with a control signal from a comparator and when samples of predetermined number or above reach consecutively a value above the threshold level, a segment detection signal is outputted to the main control section of a succeeding MODEM to start the equalizer adjustment processing. The extraction quantity in the baud timing component is made largest in the repetitive pattern segments for the entire period of turn-on sequence. Thus, the prescribed repetitive patterns segment is detected base on the extraction quantity.

Title: Optical character reader
Inventor: SETO TOSHIO
IPC: G06K9/20
Filed: 1986-12-05
Abstract: PURPOSE:To improve the resolution of a necessary part without dropping a normal reading speed and increasing recognition time by increasing the resolution by a resolution switching means when the number of recognition-disabled characters stored in a storage means reaches a previously fixed value, and reading the characters again. CONSTITUTION:In normal reading operation, an accuracy switching circuit 15 is set up to low (rough) accuracy. In case of reading, total image data to be transferred to a character recognition circuit 9 is reduced as compared to the case reading out data at high accuracy, so that all processing time including reading time for one page of a scanner part, data transfer time and recognition processing time can be reduced. When there is no coincidence at the time of comparing with a recognizing dictionary circuit 7, the number of characters impossible of being recognized is counted in each line or row by a misrecognized character number counter 14, and when the count value exceeds a set value, the state is transmitted to a control part 10 and the same line is recognized by changing the accuracy. Thus, only the area including many small characters or complex characters impossible of being recognized is read out at high resolution.

IPC: F24H1/10
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To eliminate unnecessary anxiety from a user by an arrangement wherein an abnormality indication prohibiting means prohibits the abnormality indicating operation when a heat insulation control means is operating to keep the hot water in a heat exchanger within a specified temperature range in preparation to next delivery. SOLUTION: A hot water supply apparatus comprises a combustion chamber 11, a burner 12 disposed at the lower part of the combustion chamber 11, and a heat exchanger 13 for transmitting heat from the burner 12 to water supply disposed above the combustion chamber 11. The heat insulation control section 51 on a control board 50 tires the burner 12 under a state of no water supply to keep the hot water in the heat exchanger 13 within a specified temperature range.
