Title: Universal rolling method and device therefor
Inventor: HOKIMOTO TATSUYA
IPC: B21B1/08
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To roll shapes having high quality without difference in flange thickness and web deviation by making the diameter of a vertical rolls on one side larger than that on the other side and rolling a rolled stock as pushing the horizontal rolls in the direction of the vertical roll whose roll diameter is smaller. SOLUTION: A pair of upper and lower horizontal rolls 13, 14 and a pair of right and left vertical rolls are arranged around a rolled stock 12 for manufacturing a wide flange shape and the rolled stock 12 is rolled with these rolls 13-16. The roll diameter D1 of the vertical roll 15 is set larger than the diameter D2 of the other vertical roll 16, rolling reaction force P1 of the vertical roll 15 having larger roll diameter is made larger than the rolling reaction force P2 of the vertical roll 16. Rolling is executed as always pushing the horizontal rolls 13, 14 against the vertical roll 16 whose roll diameter is smaller.  Then, the difference caused by operation variation in the roll clearances between the vertical rolls 15, 16 and the side faces of the horizontal rolls 13, 14 are not generated and the wide flange shape without the difference in the flange thickness and web deviation is rolled.

Filed: 1980-05-13
Abstract: PURPOSE:To obtain high precision by eliminating an error due to a contact potential difference by performing a chemical plating treatment after smoothing surfaces of metallic parts such as housing, oscillating electrodes, a detection electrode, and an electric-field shielding block. CONSTITUTION:Surfaces of metallic parts, such as housing 1, electric-field modulators 2 made of oscillating electrodes, a detection electrode 3, and an electric-field shielding block 4, are somoothed by lapping, etc., to the same state. Then, they are chemically plated with the same metal having a small tendency to ionization, e.g. gold and silver. A probe is formed by using thus treated metallic parts, so that no contact potential difference is developed among contact surfaces of the metallic parts. Thus, an error due to the contact potential difference is eliminated to improve the precision.

Title: Data transmitter
Inventor: TACHIKA KATSUHIKO
IPC: H04B5/00
Filed: 1994-03-31
Abstract: PURPOSE:To make the transmitter small and to reduce the power by sending a data signal depending on a content of data to be sent when a trailing ridge of a reception signal is detected so as to eliminate the need for an oscillation circuit to activate a clock means. CONSTITUTION:A transmission reception coil of a data carrier receives a power carrier signal SL1 sent from a transmission coil of an antenna, and the transmission reception coil is resonated by driving transistors(TRs) to send a data signal SL2a. In this case, the data signal SL2a is sent from the data carrier in a timing synchronously with a transmission end timing of the power carrier signal SL1 sent from the antenna. Thus, even when a charge end timing of a capacitor C1 is delayed due to a change in the distance between the antenna and the data carrier, the data signal is sent from the data carrier at an intermittent point of the power carrier signal SL1 at all times and then the transmission reception of data are accurately conducted.

Title: Scroll compressor
Inventor: SAITO JISUKE
IPC: F04C18/02
Filed: 1994-03-31
Abstract: PURPOSE:To make a piping system outside a compressor commonable as well as to promote a decrease in cost and an improvement in reliability by constituting this compressor in use of a condensed refrigerant solution as a fluid to apply back pressure to a power-save valve for letting a part of refrigerant gas in the stage midway in compression to a low pressure chamber from a compression space in time of partial load operation. CONSTITUTION:In time of full-power operation, back pressure is applied to a power- save valve 68, closing it, with a refrigerant solution fed to a refrigerant passage 64 from a refrigerant circuit at the outside of a compressor, thereby interrupting an interval between two ports 56 and 58, and any motion of this power-save valve is stopped. In brief, refrigerant gas inhaled in a compression space is fully compressed and then it is discharged out. On the other hand, in time of partial load operation, a supply of the refrigerant solution from the refrigerant circuit at the outside of the compressor is stopped, and any pressurization of the refrigerant solution from the refrigerant solution passage 64 is de-energized, whereby the power-save valve 68 is opened, and thus an interval between both the ports 56 and 58. With this constitution, the partial refrigerant gas inhaled in the compression space from the low pressure chamber is put back to this low pressure chamber, degrading the capacity of the compressor, and thus a power-saving state is secured.

Title: Continuous word recognition apparatus
Inventor: SEKOE HIROAKI
IPC: G10L15/10
Filed: 1981-04-27
Abstract: A system for recognizing a continuously spoken word sequence with reference to preselected reference words with the problem of coarticulation removed, comprises a pattern memory for memorizing demi-word pair reference patterns consisting of a former and a latter reference pattern segment for each reference word and a word pair reference pattern segment for each permutation with repetition of two words selected from the preselected reference words. A recognition unit is operable as a finite-state automaton on concatenating the demi-word pair reference patterns so that no contradiction occurs at each interface of the reference patterns in every concatenation. It is possible to use the automaton in restricting the number of reference patterns in each concatenation either to an odd or an even positive integer.
