Title: Japanese analysis device and computer readable recording medium recording japanese analysis program
Inventor: KOBAYASHI IKUAKI
IPC: G06F17/30
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To rationalize the retrieval range of a Japanese dictionary to improve the retrieval efficiency when the dictionary is retrieved to analyze the Japanese morphemes and go increase the processing speed of a Japanese analysis device. SOLUTION: The types of characters of KANJI (Chinese character) and HIRAGANA (cursive form of Japanese syllabary) parts of an inputted Japanese sentence are decided, and the KANJI and HIRAGANA are replaced with numeric characters 1 and 0, for example, respectively and stored. These numeric characters are used as keys to divide the inputted sentence into the same character type. Then the inputted sentence is divided into characters strings of combinations of the prescribed character types as the character strings to be retrieved by noticing the combinations of character types. Only the character strings of combinations of similar character types are set as retrieval object among a Japanese dictionary to improve the retrieval efficiency of the dictionary.

Title: Position adjustment of top member of ink jet head
Inventor: BABA TAKESHI
IPC: B41J2/16
Filed: 1995-04-27
Abstract: PURPOSE: To enable the position of a top member to be adjusted precisely by a minimal number of times of adjustment by adjusting the position of the top member as the top member remains pressed against a heater board, then once releasing this pressed state, and again disengaging the top member with the heater board under this pressed state. CONSTITUTION: A holding spring is released from a clamping state after a top member 104 is protruded to the tip of an adjustment rod 42 by a leaf spring 264 (b). Next, this clamping state is restored and the holding spring is returned to a natural state (c). Further, the adjustment rod 42 is moved by an amount of deviation in the position of a first discharge orifice with the top member 104 protrude to the tip of the adjustment rod 42. However, the top member 104 is deformed (e). For this reason, the top member 104 after adjustment of its position is once pressed against the tip of the adjustment rod 42 using the leaf spring 264, so that the holding spring is once released from the clamping state and again is restored to the clamping state (f).  The holding spring is returned to a natural state (g) and consequently, the top member 104 is stationary at its adjusted position, if both leaf spring 264 and adjustment rod 42 are separated from the top member 104.

Abstract: PURPOSE:To achieve a purpose without forming a groove in the seal member containing part of a body, by a method wherein a stopper ring is nipped by means of a cut-part-bent pipe, into which a coil spring is inserted. CONSTITUTION:In a spring member 5, a pipe with a thin thickness wall is bent to form an annular shape, the pipe is cut along the whole length in the longitudinal direction of the pipe, and the cut part is bent outwardly of the pipe to form a cut-part-bent pipe 3. Further, the pipe has a coil spring inserted into the bent pipe 3 throughout the overall length. Moreover, it has a stopper ring 4 nipped by the bent part of the cut-part-bent part. Since the spring member 5 itself has the stopper ring 4, even when an excessive compression load is applied on the spring member 5, compressive deformation strain can be prevented from occurring.

Title: Analog modulation circuit of laser diode
Inventor: MATSUSHITA KIWAMU
IPC: H04B10/00
Filed: 1985-05-16
Abstract: PURPOSE:To drive a laser diode under a stable and constant high frequency superimposing condition by controlling a sperimposed high frequency current amplitude in response to the temperature change in the differentiation quantum efficiency of the laser diode and applying amplitude limit so that the negative peak of a high frequency current is not below a prescribed positive current. CONSTITUTION:The amplitude of an analog signal current inputted to the laser diode 1 from a laser diode drive circuit 2 is increased/decreased in inversely proportion to the change in the differentiation quantum efficiency. Thus, after a voltage across a monitor resistor 6 is amplified by a differential amplifier 7 and the amplified result is fed to a peak detector 8. A differential amplifier 9 outputs a voltage difference between an output voltage of the peak detector 8 and a reference voltage Vr to a variable attenuator 11, which changes a high frequency current amplitude fed from a high frequency signal generator 4 to the laser diode 1. Thus, the amplitude of a superimposed high frequency optical signal is constant even when the differentiation quantum efficiency is changed. On the other hand, a high frequency amplitude limit circuit 12 clips the peak value of the superimposed high frequency voltage (current) inputted from the variable attenuator 11 so that the peak is not smaller than a prescribed positive clip voltage (current) inputted to a reference voltage (current) input terminal 13.

Title: Reducing projection exposure unit
Inventor: TERASAWA TSUNEO
IPC: H01L21/30
Filed: 1984-05-25
Abstract: PURPOSE:To enable all the chips on a wafer to be position detected, by providing an original pattern rotating table for rotating an original pattern by the same quantity of rotation as the quantity of rotation of the wafer measured by a biaxial pattern detector independent from an exposing optical system. CONSTITUTION:An X-Y stage is positioned such that one of the patterns 6 in two chips spaced by a certain distance in the X direction on a wafer 4 is disposed below a biaxial detector, in order to measure the position of the pattern. The position of the other pattern is also measured in a similar manner, so that the error in rotational mounting of the wafer is obtained with respect to the X-Y stage from the difference in Y coordinate component between the values thus detected. From the difference in X coordinate component, the magnitude of expansion of the wafer is obtained. A reticle 2 is rotated with a rotating table 13 by a quantity equal to the quantity of rotation of the wafer, and thereafter the X-Y stage is fed at a constant ratio according to the result of detection so as to expose the pattern. According to this construction, there is no need of providing a rotary table for the wafer nor more than one optical system for effecting detection.
