Title: Data base access method
Inventor: KOBAYASHI NOBUYUKI
IPC: G06F17/30
Filed: 1991-12-11
Abstract: PURPOSE:To facilitate designing a hash function according to the distribution of an access key to rialize a high speed hash access method using the hash function in a data base access processing. CONSTITUTION:In a hash access method which directly obtains the storage page of the access-intended record by an access key for the record, an element showing the range for an element to be distributed close to the consecutive numbers as well as the element showing the distribution close to the consecutive number are chosen among the components of the access key (101). The subtraction method is used for an element close to the consecutive number for each value of the element showing the range, and the access is executed by obtaining the storage page based on the subtraction while referring to the control table storing the parameter of the subtraction for each range (104).

Title: System provided with device for reducing power consumption and method therefor
Inventor: BRONNER PETER E
IPC: H04B7/26
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To reduce the entire power consumption of a receiver and to extend the service life of a battery by reducing the power consumption of a mixer inside a signal path in the case where RSSI signal has indicated that the strength of information signals is large. SOLUTION: RSSI (reception signal strength indicator) signals are used and an RF mixer 220 is switched between a high power mode and a low power mode by using a hysterisis comparator 275. The hysterisis comparator 275 controls a current drawn out from a fixed current source 221. In the case that the RSSI signals are sufficiently large and reliable reception is possible in the low power mode, a high current is switched to a low current inside the RF mixer 220. Further, by incorporating a hysterisis function in a control loop, in the case that antenna signals are changed near a switching threshold value, an instable switching mode is evaded. The execution of the hysterisis function includes a gentle transition area for not sharply changing the current inside the current source.

Title: Magnetic particle testing method
Inventor: MORINAGA YASUHIKO
IPC: G01N27/84
Filed: 1991-12-11
Abstract: PURPOSE:To accurately discriminate the presence/absence of a defect in the level-difference section, edge section, valley section, etc., of components having complicated shapes by magnetizing an object to be measured and sprinkling fine magnetic particles over the object so that the magnetic particles can adhere to a crack or flaw, and then, detecting the crack or flaw with a measuring section by changing the intensity of magnetization. CONSTITUTION:The magnetization of a work 1 is performed by composite magnetization by utilizing an axial current flow from a coil 4 and brush 5. At the time of measuring a valley section, the work 1 is weakly magnetized by making a weak current to flow through the work 1. Then magnetic particles are sprinkled over the magnetized work 1 from a magnetic particle spray 6 while the work 1 is rotated by means of a driving source. By detecting the rotation angle of the work with a rotation angle sensor 7, a strobe 8 is turned on at a preset rotation angle and the picture of the adhering state of the magnetic particles to the work 1 is taken with a TV camera 9. The taken picture is processed and decided by means of a picture processor 10. Then the intensity of magnetization is increased and the picture of the ridge section of a spline section 2 is taken, processed, and decided. Since the magnetic flux density at the valley section is increased in excess of a required level, a masking process is performed during the course of picture processing for cutting off a section increased in magnetic flux density.

Abstract: PROBLEM TO BE SOLVED: To minimize execution of changeover of a transmission antenna by executing the operation of changeover of the transmission antenna only when the reception quality is improved by switching the transmission antenna. SOLUTION: A discrimination circuit 213 of a mobile station measures the number of paths of an outgoing channel and discriminates the necessity of execution of antenna selection only when the number of the paths is smaller than a threshold value, and discriminates that it is not required to execute antenna selection in other cases. A multiplexer circuit 214 multiplexes a control signal denoting the discrimination result of the discrimination circuit 213 on transmission data and transmits the multiplexed transmission data.

IPC: C25D9/10
Filed: 1989-12-19
Abstract: PURPOSE:To improve press formability and chemical conversion treating property by coating the surface of a galvanized steel sheet with an Mo-oxide film in which Mo content is specified. CONSTITUTION:The surface of a galvanized steel sheet is coated with an Mo- oxide film by 5-500mg/m<2> expressed in terms of Mo by means of electrolysis, etc. The Mo-oxide film is formed into a glassy film similarly to a chromate film, and the occurrence of the galling of plating to a die can be prevented at the time of pressing and sliding characteristics can be improved. Further, since the Mo-oxide film is dissolved in a chemical conversion treating solution, a chemical conversion treated film can be formed. Moreover, no adverse effect is produced even if the Mo-oxide film is eluted in the chemical conversion treating solution. Since this oxide film is free from dissolution even in a cleaning stage by the use of oil and a degreasing stage, deterioration in lubricity can be prevented and also the application of load to the other stages can be prevented.

Abstract: PURPOSE:To attain high resolution for a small sized CRT by giving a signal outputted to a collector of a color signal transistor(TR) to bases of 1st and 2nd buffer TRs and outputting a color signal from an emitter of each buffer TR to a cathode of the CRT.
