Title: Normal/reverse switching device of reverse recording and reproducing device
Inventor: IDA KATSU
IPC: G11B15/44
Filed: 1985-09-09
Abstract: PURPOSE:To store mechanically the shake direction in the reproducing (recording) mode preceding the stop mode in a switching lever by using U-shaped springs placed in both sides of a part to be pressed of the switching lever. CONSTITUTION:When a driving rod 60 is moved back by switching to the stop mode, a pair of control parts 66 and 67 of the driving rod 60 are brought into contact with a pair of parts to be controlled by a switching lever 73 simultaneously to hold the switching lever 73 in the neutral position, and the shake direction in the reproducing (recording) mode preceding the stop mode is stored mechanically in the switching lever because a part 75 to be pressed of the switching lever is pressed from one side or the other by one end part or the other of a spring 69. Consequently, normal running or reverse running before the stop mode is restored automatically when the mode is switched to the reproducing (recording) mode. Since one end part or the other of one approximately U-shaped spring 69 is pressed from the inside to the outside by a spring pressing part of a switching rod and the switching lever 73 is pressed and shaken by the other end part or one end part of the spring 69, the mechanical storing function is attained with simple structure.

Inventor: CHIYUN KEI CHIYAN
IPC: G11C16/06
Filed: 1994-08-24
Abstract: PURPOSE: To repair a defective column separately by sector by providing plural sector base redundant blocks having a redundant line of a memory cell and a sector selection means for dividing into different segments. CONSTITUTION: An array 10 of a flash EEPROM cell is composed of four sector base redundant blocks 2, 4, 6, 8 and eight sectors 12-26. Respective redundant blocks are incorporated in corresponded sectors, e.g. the block 2 existing in the sectors 12, 14. The sector selection circuit in the block 2 is used for separating the redundant columns existing in the sectors 12, 14 and can independently use them. By using the sector selection circuit for separating the redundant column to different segments, individual segments existing in the specified sector is made independent of another segment in the same column, and thus, it is used for exchanging or repairing the different defective column.

Title: Magnetic head
Inventor: EGAWA MOTOJI
IPC: B65D41/04
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head capable of appropriately applying adhesive and reducing magnetic resistance. SOLUTION: A hole 18a is formed on a recessed groove 18 of a first outrigger 9A. When a front core 2 is joined with a back yoke 3A, the adhesive 50 can be applied on or injected into a butting part between a third leg part 22A and the front core 2 through the hole 18a, and the applying or injecting work of the adhesive is performed without receiving interference of another member. Thus, since the front core 2 is joined surely with the back yoke 3A, the magnetic resistance is easily kept to the low value, namely, the lowering of reproducing output and the production of read-out error are prevented. Since the hole 18a is provided on the recessed groove 18, the adhesive 5 is prevented from flowing out to a slide surface with a magnetic recording medium even when much adhesive 50 is supplied to the hole 18a.

Title: Machine for selecting and recovering empty can
Inventor: NEGISHI KOSABURO
IPC: B30B9/32
Filed: 1992-07-27
Abstract: PURPOSE:To make it possible to select an empty bottle, steel can, and aluminum can which are fed through one feed port. CONSTITUTION:If a recovered item is an empty bottle, since the bottle is heavier than an aluminum can and steel can, the restriction of a first rotation restriction member 32 is released by the empty weight of the bottle and a shooter 31 rotates downwards, so that the bottle is stored on the side of an empty bottle storage chamber. If the recovered item is a steel can, the steel can rolling over the shooter 31 causes a magnet fixing plate 34 to be sucked up, so that a second rotation restriction member 33 is moved in a restriction release direction. As a result, the shooter 31 rotates downwards and the steel can is stored on the side of a steel can storage chamber. If the recovered item is an aluminum can, neither the first member 32 nor the second member 33 is released from restriction, and hence the aluminum can on the shooter 31 rolls to the delivery side of the shooter 31 and is stored on the side of an aluminum can storage chamber.

Title: Through-hole printing method of thick film substrate and printed substrate holder
Inventor: KIMURA YOSHITSUGU
IPC: H05K3/42
Filed: 1988-08-11
Abstract: PURPOSE:To protect the rear side of a substrate against contamination by a method wherein one of printed thick film substrates produced in the same lot is made to serve as a paste contamination preventing substrate, and through- holes are made to be coincident with each other when the printed thick film substrate and the paste contamination preventing substrate are laid overlapping each other. CONSTITUTION:One of printed thick film substrates 6 produced in the same lot is used as a paste contamination preventive substrate 7. The substrate 6 is overlapped with the substrate 7 making through-holes 11 coincident with each other and fixed. Thick film paste is printed inside the through-hole 11 through sucking the paste into the through-hole 11 by reducing the air pressure on the substrate 7 side. Then, even if the paste is printed as being sucked into the through-hole 11, the excessive paste is almost sucked toward the suction hole of the board 7. By these processes, the through-holes 11 are made to coincide with each other when the substrates 6 and 7 are laid overlapping each other, so that the substrate 6 is prevented from being contaminated.

IPC: B24B37/00
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a polishing apparatus which detects the front and rear surfaces at a stage, before a wafer is placed on a chuck table and prevents polishing failures beforehand, when a workpiece such as a semiconductor wafer or the like is polished. SOLUTION: A protective tape is stuck on a surface (circuit surface) of a semiconductor wafer to be polished. Presence of this protective tape is detected by front/rear detecting means 5 disposed in carrying means to identify the front or rear surface of the semiconductor wafer. Therefore, even if the semiconductor wafer is housed incorrectly in a cassette of the front/rear directions, the wafer is carried correctly to a chuck table by checking the direction by the front/rearface detecting means 5. Thus, polishing of a surface side on which a circuit is formed can be prevented beforehand. As the front/rear detecting means 5, sensors detecting color, concentration, reflectance, hardness and the like can be applied.

Filed: 1988-08-10
Abstract: PURPOSE:To restrain the generation of abnormal sound during braking in a brake drum in which brake linings on the outer periphery of brake shoes are brought into pressure contact with the inner face of the brake drum to carry out braking by making the rigidity on the center portion of the brake shoe higher than on both side portions. CONSTITUTION:As a brake lever is held, a brake cam 6 is rotated separating brake shoes 4 from each other centering around an anchor pin 5 and brake linings 4h are brought into pressure contact with the inner face 3a of a brake drum 3 to obtain braking force. The brake shoe 4 is formed by linking a circular arc shaped inner rib 4a and an outer rib 5c with a vertical rib 4b in a body, and the vertical rib 4b is formed to be thicker toward a center portion 4g side. Accordingly, the vicinity of the center portion 4g which has a large section modulus and rigidity can be brought into pressure contact with the inner face 3a of the brake drum 3 more strongly than both side portion without causing elastic deformation. Hence, the vibration of both ends of the brake shoe 4 is less, thereby restraining the generation of abnormal sound.

Filed: 1992-07-28
Abstract: PURPOSE:To enhance safety and efficiency by forming a first passage of a large diameter for passage of the air sucked by a fan through a hot air heater and a moisture absorbent in this order and a second passage of a small diameter in parallel with this first passage within a casing and mixing high-temp. high-moisture air and ordinary- temp. and low-moisture air at the time of regenerating the moisture absorbent. CONSTITUTION:Only the fan 7 is driven to introduce the air A1 in a housing from an inlet for moisture absorption into the casing 1 and to circulate the ordinary-temp. dry air successively passed through the de-energized hot air heater 8 and a silica gel 9 together with the air, which is not dehumidified, of the second passage 12 from an outlet side for moisture absorption into the housing at the time of moisture absorption. Since the quantity of the air passing the second passage 12 is small, the dehumidifying function in the housing is not impaired. The operation is changed over to a regeneration state when the silica gel 9 is saturated with the moisture by absorbing the moisture. The fan 7 is then driven to introduce the air A1 outside the housing from an inlet 4 for regeneration and the hot air A2 of a high temp. and high humidity past the silica gel 9 heated by the hot air heater 8 is mixed with the air A1 of the ordinary temp. and ordinary humidity in the second passage 12 in an outlet 5 for regeneration, from which the air mixture is discharged to the outside.
