Title: Picture processor
Inventor: TAKAGI YUICHI
IPC: G06T1/60
Filed: 1991-02-22
Abstract: PURPOSE:To quickly perform the window switching processing by preliminarily storing picture data in a picture memory in terms of window. CONSTITUTION:Picture element data of plural windows are stored in a picture memory 3 in terms of window, and a change point coordinate register 4 where the coordinate point address of the change point of each window is stored is provided. At the time of drawing, addresses of respective picture elements on the display picture are designated while being two-dimensionally scanned by an address scanner 5. Picture data in designated addresses are read out from a display picture area of the picture memory 3 in order to draw a picture, and the designated address is always compared with each coordinate address in the change point coordinate register 4. When the coordinate address coinciding with the designated address is found, a certain value address different among windows is added to the designated address, and the addition result is supplied to the picture memory 3 as the read address.

Abstract: PROBLEM TO BE SOLVED: To efficiently compress both long and short character strings. SOLUTION: A symbol string detecting means 1 detects a second symbol string which matches with the first symbol string of a prescribed length (n) out of inputted symbol strings.

Filed: 1990-03-01
Abstract: PURPOSE:To automatically perform impedance matching between the power source side and the load side in a short time by controlling capacities of first and second capacity varying means based on the load and the phase difference of a high frequency power source, the frequency value of the power source, etc. CONSTITUTION:A phase difference and absolute value ratio calculating circuit 5A of a controller 5 calculates a phase difference theta between the high frequency current and the high frequency voltage and a ratio of their absolute values. A conductance and susceptance calculating circuit 5B calculates a conductance G and a susceptance B and sends them to an arithmetic circuit 5E. The characteristic impedance on the high frequency power source side peculiar to a device and a signal indicating the frequency are preliminarily supplied to the circuit 5E. The circuit 5E uses respective supplied values to perform the operation to calculate a capacity for impedance matching between the power source side and the load side and supplies it to a matching variable capacitor 2B and a tuning variable capacitor 2A through capacity control circuits 5C and 5D. As the result, impedance matching between the power source side and the load side is quickly and automatically performed.

Title: Semiconductor device
Inventor: MATSUOKA TSUGUHIRO
IPC: H03K19/017
Filed: 1984-03-16
Abstract: PURPOSE:To obtain an inverter circuit with high speed rising and less power consumption by using an enhancement (E)MOSFET as a load FET of an inverter and connecting a capacitor between its gate and source. CONSTITUTION:Since an EMOSFETQ5 is turned off and a depletion MOSFETQ8 is turned on when an input Vin is inverted from H to L, a power is supplied from the EMOSFETQ9 and the level of nodes N1, N2 is subjected to rising. When the node N1 gets higher in its level and the FETQ8 is turned off, the node N2 rises rapidly and a capacitor C is charged. When the charging voltage is applied to the gate of the FETQ5 and the FETQ5 starts turning on, the level of the node N1 rises rapidly and then the node N2 rises further because of the bootstrap effect of the capacitor C, the FETQ5 is turned on at high speed and the node N1 rises rapidly up to the power voltage. Since the EMOSFET is used, the power consumption at L level output is decreased.

Title: Wedge bulb
Inventor: INOUE AKITO
IPC: H01K1/44
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To eliminate nonconformity of a residual tipping part (such as breakage, cracking, or generation of leak or the like), and eliminate need of strict temperature control for a tip-off burner. SOLUTION: In this valve 1, a tipping part 160 is flattened by a pinch 4 after its air discharge tube is fused. As a result, protrusion height of the residual tipping part 160 on the air discharge tube can be set lower than that of a conventional wedge bulb, so nonconformity by the residual tipping part 160 can be eliminated. By flattening the tipping part 160 after fusing the air discharge tube, the tipping part 160 can be surely sealed, so the flame temperature of a tip-off burner can be set lower, thereby need of strict temperature control for the tip-off burner is eliminated.

Title: Crossroad vehicle sensor device
Inventor: FUJIWARA HIDETOSHI
IPC: G01S17/58
Filed: 1994-02-14
Abstract: PURPOSE:To prevent the suddenly meeting accidents of vehicles on a crossroads by emitting a laser beam to a reflector provided on the crossroads and receiving the light reflected from the opposite party vehicle to calculate the relative speed to the opposite party vehicle. CONSTITUTION:The laser beam transmitting and receiving parts are formed at the front side of a vehicle. An inter-vehicle distance calculator 30 calculates the inter-vehicle distance based on the data received from a laser head 2, and a relative speed arithmetic circuit 31 calculates the relative speed to the vehicle ahead and the speed of this vehicle based on the inter-vehicle distance data. Then a curved road reflector judging circuit 36 judges a curved road reflector. The optical path of the laser beam emitted from its own vehicle is changed by the reflector provided on a crossroads. Then the reflector irradiates the laser beam to the vehicle coming on a wrong way and the optical path of the reflected light of the vehicle is changed again by the reflector. The reflected light of the wrong-way vehicle is led to its own vehicle. Thus the wrong-way vehicle is detected by the time difference caused between the emitted and reflected waves.

Title: Kana-kanji converting system
Inventor: KATABAMI HIROSHI
IPC: G06F17/22
Filed: 1983-03-26
Abstract: PURPOSE:To improve the KANA(Japanese syllabary)-KANJI (Japanese syllabary) (Chinese character), converting efficiency of a Japanese word processor by feeding a Japanese sentence after dividing it into prefixes, independent words and the rest clauses for each clause of reading KANA characters and then inserting blanks and dividing marks among said divided sections. CONSTITUTION:A Japanese sentence is divided into prefixes, independent words and the rest clauses for each clause of the reading KANA characters. Then blanks or specific marks are put among those divided sections by means of a key 11. A read input circuit 2 checks the reading characters, and access is given to a prefix dictionary if a blank or a dividing mark is detected. When an OK is obtained, an ordinary dictionary is used. If the OK is not obtained, HIRAGANA (cursive form of KANA) is decided. An access is given to the ordinary dictionary when no blank nor dividing mark is detected. If an OK is obtained, the prefix dictionary is used. While access is given to a proper noun dictionary if no OK is obtained. If an OK is obtained with the proper noun dictionary, access is given to the prefix dictionary with checking done with a grammar dictionary. Then the KANA/KANJI conversion is performed if an OK is obtained. When no OK is obtained with the proper noun dictionary and the grammar dictionary, the number of the retrieved characters is decreased by one character from the rear side. Then the ordinary dictionary is used again to repeat the above-mentioned procedure.
