Patent JP-H0290167-A (JP)
Title: Semiconductor producing device
Inventor: ABE KEIZO
IPC: H01L21/027
Filed: 1988-09-27
Abstract: PURPOSE:To remove only the resist from the peripheral section of a base plate without giving any influence to the surface of the base plate by providing a pressure vessel and degassing valve in the vicinity of the discharging section of a pipeline system for discharging a solvent. CONSTITUTION:A pressure vessel 7 is provided in the vicinity of a discharge nozzle 5 in the middle of a pipeline 9 and a degassing valve 8 is installed to the vessel 7. Therefore, only a solvent 2 can be discharged from the nozzle, since the solvent is separated from the gas dissolved in the solvent and discharge of a mist in which the gas is mixed with the solvent can be avoided. Accordingly, only the resist in the peripheral section can be removed without giving any influence to the applied photoresist.

Title: Hoisting machine
Inventor: MATSUMOTO KUNIO
IPC: B66D5/22
Filed: 1992-09-10
Abstract: PURPOSE:To provide a hoisting machine preventing an inconvenience such as a mechanical brake being unreleasable in the hoisting machine provided with a slip clutch and a mechanical brake. CONSTITUTION:In a slip clutch for a hoisting machine, the average diameter of a facing 41 working effectively at the hoisting time and a facing 42 working effectively at the lowering time is changed so as to set the action torque of the slip clutch to the relation of hoisting side action torque < lowering side action torque. With the action torque on the hoisting side of the slip clutch being set relatively low, the release torque of a mechanical brake linked with the slip clutch can be also suppressed low, and an inconvenience such as the mechanical brake not being releasable can be prevented completely since the lowering side action torque can be set relatively high.

Title: Multitrack head and production thereof
Inventor: OKUWAKI TOYOJI
IPC: G11B5/29
Filed: 1989-09-20
Abstract: PURPOSE:To form tracks at a smaller pitch by providing a gap for recording and reproducing in the direction perpendicular to a substrate, inclining this gap at a slight angle from a right angle and laminating plural pieces of magnetic head elements in the direction perpendicular to the substrate. CONSTITUTION:A magnetic path is formed of the film on the substrate surface and the gap g for recording and reproducing is formed in the direction perpendicular to the substrate surface. The gap g is formed by setting the azimuth angle thetawith the substrate 11. Plural pieces of the magnetic heads 21 are laminated in the direction perpendicular to the substrate 11 and the head is so constituted that the azimuth angle theta varies between the adjacent magnetic heads 21. The small-sized multitrack type head of an extremely narrow track width is formed in such a manner and the crosstalk between the tracks, etc., are prevented. The spacing is reduced and the ultra-high track density is thus obtd.

IPC: H01L21/60
Filed: 1989-09-19
Abstract: PURPOSE:To improve the yield of production and reduce production cost by indicating acceptance test results of carrier tape to an alignment mark and mounting a semiconductor element only with a good quality of carrier tape. CONSTITUTION:An inner lead bonder takes in an image of binary alignment marks, calculates the area of a round hole to obtain a gravity coordinates of the round hole, and then calculates the deviation against the gravity coordinates 8 of the round hole, moves the position of a carrier tape or a semiconductor element, aligns an inner lead with an electrode of the semiconductor element, and carriers out bonding operation. The carrier tape where the round hole of the alignment mark is expanded because it is decided as defective by a carrier tape tester results in a larger hole compared with the round hole of an alignment mark formed on a non defective carrier tape. Therefore, it is possible to bond a semiconductor element only with a non defective carrier tape during alignment by providing a boundary value of non defective and defective articles to the area of the round hole, thereby attaining enhanced yield and cost reduction of carrier tape.

Title: Laser scanning optical device
Inventor: NAGASAKA YASUSHI
IPC: G02B26/10
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To make a device compact, to restrain the distortion of a lens with the fluctuation of ambient temperature and humidity and to form an excellent image by superposing adjacent lenses through an engaging device performing the mutual positioning of the lenses at least in either direction of a main scanning direction or a lens optical axis direction. SOLUTION: Lenses 351a and 352a adjacent up and down are superposed through an engaging device 9A. Thus, the adjacent lenses 351a and 352a are mutually positioned so that they may not be deviated in the lens optical axis direction Y as well as in the main scanning direction X. Therefore, not only the adjacent lenses are mutually positioned compactly without accompanying a complicated large-scale mechanism but also the structure of a laser scanning optical device is made compact. Further, since the device 9A mitigates the mutual influence of the lenses 351a and 352a associated with the expansion or the contraction of the lenses 351a and 352a with the fluctuation of ambient temperature and humidity, the distortion of the lens is restrained so much and the excellent image is formed on an image surface.
