Title: Manufacturing method and cutting device for master magneto-optical disk
Inventor: FUTAMI TATSU
IPC: G11B7/26
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To equalize signal strength from necessary format information by forming, in a format information group, an irregular pattern synchronized with the irregular pattern formed in a format information land, in a manner linked continuously in the radial direction. SOLUTION: The irregular pattern formed in a format information group by the irradiation of a second laser beam is synchronized with the irregular pattern formed in the adjacent inner circumferential format information land by the irradiation of a first laser beam. From this, it is possible that the irregular pattern of control information and address information formed in the format information group and those formed in the format information land are nearly perfectly synchronized with each other, and that the irregular pattern is formed in a manner linked continuously in the radial direction. Thus, format information can be recognized while an optical head is made to seek between tracks.

Title: Equality type loop communication system
Inventor: KORETOMO HARUKI
IPC: H04L12/42
Filed: 1981-12-26
Abstract: PURPOSE:To attain efficient loop communication, by providing a means which can communicate plural stations each other at an arbitrary time, in a loop communication system. CONSTITUTION:In the communication from a station A to C, the station A uses a loop back connection toward a station F, and returns data from the station F to the station F. The station C stops the relay function of data from the station A and blocks the data transmission to the station D. That is, the data between the stations A and C is relayed at a station B and flows as shown in the arrow 2. Thus, when the station D obtains the right of transmission and makes transmission to the station F, the communication is done as shown in the arrow 2. If the station D transmits to the station B, since loop back is executed at the station A, it is easily known that the other communication is executed on the way to the station B.

Title: Preparation of iron disulfide
Inventor: SUMITA MORIMASA
IPC: H01M4/58
Filed: 1981-12-26
Abstract: PURPOSE:To prepare iron disulfide of very high purity stably with a high efficiency, by mixing sulfur with iron powder having at least the surface converted to a compound, e.g. iron oxide, and sulfiding the iron powder under heating in a specific temperature range. CONSTITUTION:Sulfur is mixed with iron powder having at least the surface of iron oxide or iron hydroxide, and heated at 270-690 deg.C to give iron disulfide suitable for an active material of the positive pole in a cell, etc. with a high efficiency. The iron oxide is obtained by any one of the following method: An acidic aqueous solution is added to oxidize iron powder in the absence of oxygen by the hydrothermal method. The iron powder is oxidized in the absence of oxygen under heating. An iron salt is decomposed under heating to give iron oxide. On the other hand, iron hydroxide is obtained by hydrolyzing an aqueous solution of an iron salt. The heat sulfidation reaction is slow at about 270 deg.C, and the formed iron disulfide begins to decompose at above 600 deg.C. Therefore, the temperature range of about 350-450 deg.C is preferred.

Abstract: PURPOSE:To easily manufacture a printed wiring board, wherein a circuit pattern is accurately formed on a synthetic resin surface, by injection molding by injecting synthetic resin into a cavity, after a circuit pattern is formed on a metal mold cavity side inner surface by a prescribed sequence. CONSTITUTION:Water-soluble masking material 2 is printed on a surface part 1 corresponding with a circuit pattern on a metal mold cavity side inner surface. After an inorganic resist layer 3 composed of ceramic or glass whose coefficient of linear expansion is in the range of 2.0-8.0X10<-6>/ deg.C is fixed on the whole surface, baking is performed. After only the inorganic resist layer 3 covering the upper surface of the masking material 2 is eliminated, or at the same time, the masking material 2 is eliminated with water or alkaline aqueous solution. After the metal mold cavity side inner surface is gold-plated, synthetic resin like polycarbonate is injected in the cavity, and injection molding is performed. Then after demolding, the formed product is taken out. Thereby, a printed wiring board wherein a circuit pattern 4 is transferred on an insulating base material composed of synthetic resin 5 is obtained. In this case, adhesion between the resin and the metal for circuit use is strengthened.

Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To continuously and effectively prevent snores while sleeping and to have a healthy sleep while preventing the snores. SOLUTION: At the time of mounting the head on the center of this pillow, a head part dividing part 2 expanded upwards in a curve shape naturally tilts the head to the left or right and a side head part is mounted on a head part mounting part 3a or 3b. At the time, since a neck part is rolled on a neck part mounting part 6a (or 6b), a sideways body posture is smoothly formed. When the sideways posture is attained, an airway is not narrowed and the frictional sound and vibration sound of a secretion inside the airway and tissues surrounding the airway are not generated even when breathing by the mouth is performed.  Since the neck part mounting parts 6a and 6b of different heights are respectively successively connected at the front and back in a vertical direction of the head part mounting area part, by sleeping while positioning the neck part so as to mount it on a more suitable neck part mounting part 6a or 6b corresponding to the shapes of the neck part and head part of a user, a more comfortable sleep effect is obtained.
