Title: Production of laminate having excelent dew condensation resistance and gas barrier property
Inventor: OOSEKI YUKIO
IPC: B32B27/28
Filed: 1980-09-30
Abstract: PURPOSE: To obtain a laminate having excellent dew condensation resistance and gas barrier property, by coating the surface of a thermoplastic resin film or sheet with an ethylene/vinyl alcohol copolymer resin containing a nonionic surfactant.  
     CONSTITUTION: The surface of a thermoplastic resin film or sheet is coated with an ethylene/vinyl alcohol copolymer resin, ethylene content 25W60mol%, saponi- ficaton degree ≥96%, containing 0.1W3wt% nonionic surfactant, HLB 4W16(the copolymer resin is used preferably in the form of a solvent solution). When the ethyleme content exceeds 60mol%, the has barrier property is lost and when the ethylene content is lower than 25mol%, its higher vinyl alcohol content causes poor water resistance and a decrease in gas barrier property at high humidity. Moreover, when the saponification degree of the copolymer is below 96%, the water resistance and gas barrier property of films and the so-called "nerve" of films are lowered, and the films have an acetic odor. Accordingly, such a saponification degree is not preferred.

IPC: G11B19/28
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To attenuate vibration to be transmitted to the outside, to maintain high performance to vibratory impact from the outside and to satisfactorily perform recording and reproducing operation. SOLUTION: This device is the CD-ROM drive device capable of reproducing data at standard speed, 4-fold speed and 6-fold speed respectively. When a disk is loaded, TOC information is read out under the state of standard speed reproduction (ST1). Next, the state is shifted to 6-fold speed reproduction, and also the state of holding in a prescribed address (ST2). Then, whether the disk is eccentric or mass-eccentric is discriminated by utilizing a tracking error signal and a spindle motor control signal, etc., (ST3). When the disk is neither eccentric nor mass-eccentric, the reproducing speed is set to 6-fold speed, and on the other hand, when the disk is eccentric or mass-eccentric, the reproducing speed is set to 4-fold speed. In the case of the mass-eccentric disk, the occurrence of self-exciting vibration at the reproducing time is suppressed by lowering the reproducing speed.

Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent, during switching, a traverse width from being larger than a traverse width during normal high-speed traversing by reducing the tension width of yarn with a traverse width regulation guide while reducing a traverse speed. SOLUTION: A member L-shaped in section is supported in a position opposite the right side face of the supporter 3 of a machine frame 1 so as to be swung around its upper end, and a traverse width regulation guide 28 is formed in its lower part tip. By swinging this member L-shaped in section, the traverse width regulation guide 28 is moved from a standby position opposite a traverse surface 37 to the vicinity of the end part of a yarn traverse width on the traverse surface. Then, it is moved to a position for regulating a traversed yarn traverse stroke width. A recessed part 28c corresponding to a traverse stroke is formed in the plate-like member of the traverse width regulation guide 28. Thus, during yarn switching, the increase of the traverse width caused by the reduction of a traverse speed is prevented.

Filed: 1978-11-08
Abstract: PURPOSE: To prevent leads from being bent during inspection, by cutting off the coupled portions of an outer lead frame and tie bars which connects the leads to each other, as the outer lead frame remains mounted and by fixing a semiconductor device and inspecting it.  
     CONSTITUTION: Tie bars are cut off and their tips are also cut off as an outer lead frame 13 remains mounted. A semiconductor device is then fixed. The semiconductor device is positioned on the top of a measuring socket 17. A lead hold-down block 16 is moved down to hold leads down into contact with the socket 17 to inspect the semiconductor device. If the device is regarded as all right, the leads are bent and the outer lead frame is cut off to supply the semiconductor device as a product. Because inspection steps are effected as the outer lead frame remains mounted, ambient forces do not directly act on the leads. Therefore, the leads are prevented from being bent.

Title: Super hard composite member with high toughness, and its production
Inventor: MORIGUCHI HIDEKI
IPC: C22C26/00
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To combine high toughness with high hardness in a diamond(CBN) dispersed composite member. SOLUTION: This composite member has a hard phase composed essentially of at least one compound selected from WC, TiC, TiN, and TiCN and diamond(CBN) grains and a binding phase composed essentially of iron group metal and also has a cross section containing binding-phase structures having a shape where aspect ratio is 5-20. Further, the composite material has density of >=95% theoretical density ratio. Because these binding-phase structures are flat, cracks necessarily cross the binding phases at the time of crack propagation and the crack propagation energy is dissipated by the plastic deformation of the binding phases at this time, by which high toughness can be attained.
