Title: Image forming apparatus
Inventor: OMURA IKUMI
IPC: G03G15/08
Filed: 1995-06-08
Abstract: PURPOSE: To avoid impact at the time of contact, prevent damages of an image carrying body, and carry out excellent development stably for a long duration by installing an elastic member which is brought into contact with the image carrying body before a spacer is brought into contact with the image carrying body. CONSTITUTION: Butting rollers are installed respectively in the peripheries of both ends of a development sleeve 3 and the butting rollers are composed of rigid roller parts 2 positioned in both ends and elastic roller parts 1 sandwiched between the former parts 2 and the outer diameter of the elastic roller parts 1 is a little higher than that of the rigid roller parts 2. Consequently, in the case where compressing force is applied to 21 developer and the development sleeve 3 is brought into contact with the image carrying body 6, at first the elastic roller parts 1 are brought into contact with the body 6 and then the rigid roller parts 2 are brought into contact with the body 6. As a result, the impact of the butting rollers to the image carrying body 6 due to the function of the compressing force is moderated owing to the existence of the elastic roller parts 2.

Title: Polishing device and polishing method
Inventor: MATSUKAWA EIJI
IPC: B24B37/10
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To reduce the total load for pressurization, and to almost uniformly polish a wafer by setting the size of a polishing pad smaller than the size of a polishing object member. SOLUTION: A polishing device has the polishing pad part 10 and the polishing object member part (the wafer part) 20. The polishing pad part 10 has a polishing pad 4 having the size sufficiently smaller than the size of a wafer 1 being a polishing object member, a head 30 composed of a base 5 for holding this polishing pad 4 and a vibration mechanism 9, a rectilinearly moving mechanism and a pressurizing mechanism (showing only the pressurizing direction 7).  Since a relative speed of the polishing pad 4 and the polishing object surface of the wafer 1 becomes almost uniform on the whole surface of the polishing pad 4 since the size of the polishing pad 4 is sufficiently smaller than the size of the wafer 1, the whole surface of the polishing pad 4 easily strikes on the wafer surface 1, so that polishing pressure with the polishing object surface of the wafer 1 becomes uniform on the whole polishing surface of the polishing pad 4.

Filed: 1991-07-04
Abstract: PURPOSE:To reduce the average capacity of one word and to reduce dictionary capacity by registering plural parts of speech as to one word in a dictionary part for KANA(Japanese)-KANJI(Chinese character) conversion. CONSTITUTION:Reading information of the word inputted from an input means 102 is stored in a storage means 103, and a word reading means 104 reads the word corresponding to the reading information from the dictionary part for KANA-KANJI conversion 101. A part of speech reading means 105 sequentially reads the part of speech on the having read word, and a part of speech judgement means 106 judges whether the having read part of speech is a declinable word or not. When judgement is the declinable word, a conversion candidate setting means 107 changes the ending of the word which the word reading means 104 reads. When reading information coincide, the word is set to be the candidate of KANA-KANJI conversion. When there is no part of speech to be read, the word which is set to be the candidate is outputted as the result of KANA/KANJI.

Title: Protective unit for inverter circuit
Inventor: YOSHIKAWA YOSHIRO
IPC: H02M7/48
Filed: 1992-06-23
Abstract: PURPOSE:To protect a power transistor and to electrically isolate an inverter control circuit from a base drive circuit by interrupting power supply to a light emitting element in a photocoupler which delivers a switching signal from the inverter control circuit to the base drive circuit upon detection of an overcurrent. CONSTITUTION:Upon instantaneous occurrence of overcurrent due to turn ON- OFF of a power transistor, a voltage across a resistor 22 in a first detector 21 increases to light a LED 24 in a photocoupler 23 and a high voltage is outputted from a comparator 30 in a protective circuit 27. If the overcurrent is caused by the average current flowing entirely through an inverter circuit 3, it appears at a current transformer CT for a second detector 26 and the output voltage of the comparator 30 goes high. Consequently, a transistor 33 is turned ON while a transistor 32 is turned OFF to turn a transistor 31 OFF thus interrupting power supply to the LEDs in the photocouplers 15-20.

Title: Removing apparatus for dissolved oxygen
Inventor: MATSUMOTO IKUO
IPC: F16L58/00
Filed: 1978-12-26
Abstract: PURPOSE: To decrease the corrosion of a liq. path so as to extend the life to a pipe, by arranging removably a metal such as iron plate, which corrodes through the reaction with dissolved oxygen, in the liq. path of, e.g., a warm water air conditioner.  
     CONSTITUTION: Warm water delivered from a warm water boiler 1 is fed by means of a pump 3 to each radiator 2, then it returns to the boiler 1. When the water in a circulation path is decreased, water is fed through a pipe 5, a cistern 6, and a dissolved-oxygen-removing apparatus 7 to the circulation pipe. It is mixed with a large quantity of oxygen because it comes into contact with the open air in the cistern 6. The water enters from the cistern 6 into the cylinder 13 of the apparatus 7, where major portion of the dissolved oxygen is used for oxidizing the iron plate 14. Reddish brown precipitate formed in the cylinder 13 passes through a filter 19 and is deposited near an on-off cock 20. Hence dissolved oxygen in the feed water from the cistern 6 scarcely corrodes the pipes 4, 5 or the body of the warm water boiler 1.

Title: Metal vapor laser oscillation tube
Inventor: OKADA YASUMASA
IPC: H01S3/097
Filed: 1985-07-29
Abstract: PURPOSE:To improve an energy efficiency, by supplying a pulse electric power from a high pulse voltage source to a power supplying terminal installed at the both ends of the insulating layer of the outer tube whose outer surface is coated with good conductive material. CONSTITUTION:When an electric pulse power is applied to a power supplying terminal 16 from a high pulse voltage source 7, it is impressed between electrodes 5 and 6 through the metal-coated part 19 of an outer tube 12. This induces the two-electrode pulse discharge to generate plasma in a discharge chamber 2. The discharged plasma collides with metal particles 8 in a discharge space 2 to heat up a ceramic inner tube 1 at extremely high temperature. The metal particles 8 evaporate and form a metal vapor as a laser medium so that a metal vapor laser oscillation is generated. In this manner, a pulse current flows in the direction of the arrow on the surface of a metal-coated part 19 of the outer tube 12. Said current flows into the discharge space though the electrodes 6 and 5 and forms a coaxial structure, so that the impedance of a discharge circuit is considerably decreased.
