Title: Packaging film and package
Inventor: TADA HIROSHI
IPC: B65D75/30
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent effectively alcohol from being dissipated, store a package in a sealed state in a storage container, and unseal the package easily with small pressure at a desired time by laminating a heat-seal layer formed of a vinylidene chloride resin to base material layers at least one layer of which is formed with an aluminum foil. SOLUTION: In this packaging film 1, a heat-seal layer 5 formed of a vinylidene chloride resin is laminated to base material layers 4 at least one layer of which is formed with an aluminum foil. Since a heat-sealed part A includes the vinylidene chloride resin in such a manner, impermeability to alcohol is exhibited. It is preferable that a heat-sealing temperature for forming the heat- sealed part A is in a range of 120-200 deg.C. If it is less than 120 deg.C, there is a case where the heat-seal layer 5 may not be reliably heat-sealed and, as a result, a sufficient heat-seal strength can not be obtained. Further, if it exceeds 200 deg.C, there may be a case where the heat-sealed part A is broken due to the thermal deformation or thermal melting of a synthetic resin film forming the base material layers.

Title: Laser light keyboard
Inventor: IMAIZUMI TOSHIO
IPC: G06F3/02
Filed: 1988-10-26
Abstract: PURPOSE:To obtain a new keyboard of a non-contact type by forming a laser light matrix conforming with a key array state, so that a laser light propagation path corresponding to a key operation is changed and formed by cutting an optical path by an operated key. CONSTITUTION:A laser light emitted from a longitudinal direction laser light emitting part 5 is photodetected by a longitudinal direction laser light receiving part 7, and a laser light emitted from a lateral direction laser light emitting part 2 is photodetected by a lateral direction laser light receiving part 4. When some key 8 is brought to pressure operation, its operating piece 8b cuts off the corresponding longitudinal and lateral direction optical paths in a laser light matrix and a propagation path is changed. Reflecting/refracting parts 6-1, 6-2, 3-1 and 3-2 give a propagation delay corresponding to its refractive index, and a laser light emitted to an optical path running along the side plate surface gives a phase inversion, therefore, in the propagation path which is changed and formed in the longitudinal and the lateral directions, a prescribed phase difference is generated between a laser light which is made incident and a laser light which is emitted. By measuring this phase difference, a depressed key is discriminated.

Title: Manufacture of semiconductor device
Inventor: YAMAZAKI ATSUSHI
IPC: H01L21/322
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To avoid contaminating a gate film in a channel doping step to improve the gate reliability. SOLUTION: The manufacturing method comprises a step of thinly depositing polysilicon 105 after forming a gate film. B and P are added to the polysilicon. The process of channel doping 104 by ion implanting is made through the film 105. B and P are each expected to provide the gettering effect on metals, Na, Ca, etc. After the channel doping, a second layer of polysilicon is thickly deposited to dope B/P at a high concn., thereby obtaining a polysilicon having a polarity meeting requirements. Since the gate film is treated by the ion implanting or other apparatus in the condition that it is covered with a protective film having a high gettering effect, it is highly resistive to the surface contamination.
