Title: Headphone
Inventor: SATO TOYOHIKO
IPC: H04R1/34
Filed: 1992-07-17
Abstract: PURPOSE:To improve the presence of a sound field of the headphone by controlling the quantity of crosstalk. CONSTITUTION:A parabolic reflecting plate 7 is fitted to a sounding unit 5 of an open air type having a conventional head band 4 via a support rod 6. Most of sound waves reflected toward the outside of ears is reflected in the reflecting plate 7 and returns to the ears. Since the waves return to the ears with a delay to radiating sound waves, the ears recognizes it as a phase difference component and forms the presence. Furthermore, a sense of a sound pressure is given to the surrounding of the ears and it also contributes to the presence. Moreover, the sound waves reflected and diffracted in the parabolic reflecting plate at the ends of the reflecting plate 7 reach the ear 2a or 2b at the reflecting side to provide a crosstalk component to both the ears thereby producing a sense as if the sound source were parted from the ears.

Title: Base paper for heat sensitive stencil printing
Inventor: TAKAGISHI IKUO
IPC: B41N1/24
Filed: 1981-11-28
Abstract: PURPOSE:To obtain the titled base paper for printing, wherein water soluble silicon oil layer is further applied on a heat sensitive film which is stuck on one surface of porous thin leaf paper, and which has excellent exfoliating property with respect to original copy and offers clear and sharp printed pictures. CONSTITUTION:The heat sensitive film such as a copolymer of vinylidene chloride and vinyl chloride, polyester, and polypropylene is pasted to the one surface of the porous tissue paper using, e.g. polyvinyl acetate bonding agent. The water soluble silicon oil layer is applied on the surface of said film and dried, and the aimed base paper for printing is obtained. The original copy is closely contacted on the surface of the film of the base paper.

Title: Formation of wiring
Inventor: IYAMA TSUYOSHI
IPC: H01L21/336
Filed: 1987-07-31
Abstract: PURPOSE:To prevent corrosion by a developer of a metallic thin-film when a positive resist is developed, and to reduce the disconnection generation rate of a wiring largely by forming a protective film having alkali resistance onto the metallic thin-film and selectively removing the metallic thin-film through etching together with the protective film. CONSTITUTION:A positive type photo-resist is applied onto a protective film 3, and dried to shape a positive resist film 4, and a metallic thin film 2 corresponding to the exposed section of the protective film 3 is gotten rid of together with the protective film 3 through wet etching by using a specified etchant, thus forming a desired wiring pattern. Consequently, since the protective film 3 consisting of Mo, etc., and having alkali resistance is shaped onto the metallic thin-film 2 according to the forming method of the wiring, the surface of the metallic thin-film 1 is not dipped directly into a developer when the positive resist film is developed, thus largely reducing the generation rate of disconnection.

Title: Position detector for traveling object
Inventor: KAWANO MASAMI
IPC: G03B27/50
Filed: 1983-10-14
Abstract: PURPOSE:To avoid a malfunction and to improve the reliability of a position detector for traveling object by eliminating the magnetic field of a magnet set to a reed switch only when another magnet having an opposite direction of magnetic pole comes right above the magnetic field. CONSTITUTION:When the ON-OFF control is carried out by shifting a magnet on a reed switch, the magnetic field of a magnet 72 set to the reed switch is eliminated only when another magnet having the opposite direction of polarity comes right above the magnetic field. At the same time, the direction of polarity of the magnet which drives the reed switch is set opposite to each other between adjacent columns. Therefore the magnet set to the reed switch has the opposite direction of polarity. As a result, the magnetic field is strengthened when a magnet of a column different from the magnet which drives the reed switch passes through the area near the reed switch. In this way, the generation of a malfunction is eliminated and the reliability of a position detector for traveling object is improved.
