Title: Distribution system for telegraphic message
Inventor: ITOU MASAO
IPC: H04L12/18
Filed: 1981-04-30
Abstract: PURPOSE:To properly distribute to terminals, which differ in the distribution amount of telegraphic messages, individually by circuits less than the terminals by arranging terminal name registration elements more than the terminals, and then providing a rotation table wherein they are accessed endlessly. CONSTITUTION:A rotation table 4 wherein terminal name registration elements E1, E2,... more than terminals are arranged and accessed endlessly is provided. In the elements E1, E2,... terminal names are registered correspondingly; the terminal name of a terminal having the large distribution amount of telegraphic messages use succeeding elements, and that of even a terminal having the small distribution amount of telegraphic messages use one element. Further, every terminal is provided with a terminal control table containing flags which show whether the terminal is in process of distribution and whether it has a request for distribution. Then, terminal names registered in the table 4 are accessed and read by distribution-address specifying pointers Pi provided corresponding to respective circuits of the table 4, and according to the flags in the terminal control tables of the read terminal names, decisions of connection and disconnection between circuits and the terminals are made.

Title: Method for recovering border of packet
Inventor: DOSHI BHARAT TARACHAND
IPC: H04L7/08
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To realize a simple point-to-point data link protocol(SDL) based on the use of a length indicator field and an error check field not on the use of a flag to recover a packet border in a receiver. SOLUTION: An SDL transmitter 105 sends an SDL packet consisting of a header and a PDU (payload) of a variable length. The header consists of a length indicator (L1) field, a type field and a cyclic redundancy check CRC field. A receiver 150 blocks a packet as a function of the LI field to conduct self-synchronization as functions of the LI field and the header CRC field, that is, recovers the packet. In the recovering the packet especially, the receiver 150 applies CRC check to each reception SDL packet header and declares synchronization after the check by N times (e.g. N=4) is correct.

Title: Switching system of memory circuit
Inventor: NARAHIRA SADAO
IPC: G06F12/06
Filed: 1983-04-15
Abstract: PURPOSE:To attain an automatic switch between the 1st and 2nd memory circuits by using a logical circuit which selects the 2nd or 1st memory circuit in accordance with the presence or absence of connection of the 2nd memory circuit. CONSTITUTION:For the RAM capacity X, A and C show an ROM area and an RAM area, respectively. When an ROM board 1 is cut off, the ''1'' level is supplied from an RAM selection signal input terminal IN2. At the same time, the ''1'' level is delivered from an output terminal OUT1. Furthermore the ''1'' level is supplied also from an input terminal IN1. Therefore an electric power supply +Vcc is applied to the terminal of one side of an AND gate G, and this output is set at level ''1'' and delivered to an output terminal OUT2. Thus both areas A and C are used to the RAM area. When the board 1 is connected, an earth is connected to a terminal of the gate G and this output is set at level ''0''. Then only the area C is used as the RAM area. In such a way, an automatic switch is possible between the ROM and RAM areas with use of a logical circuit.

IPC: G11B9/08
Filed: 1989-03-18
Abstract: PURPOSE:To allow the reading of the electrostatic patterns of a charge holding medium having a high resolution with the accuracy of a molecular level by short-circuiting the electrodes of an electrooptical element and the charge holding medium from each other, making light incident to the electrooptical element and reading charge patterns by transmitted or reflected light. CONSTITUTION:The transparent electrode 101c is provided between glass 101b and an orientation layer 101d and is short-circuited from the electrode 103b of the charge holding medium 103 formed with the electrostatic patterns. The orientation layers 101d, 101f are so disposed that the directions of the orientation intersect orthogonally a 90 deg. with each other and, therefore, if the light polarized in the direction perpendicular to, for example, the plane of the figure is made incident from an antireflection layer 101h side, 90 deg. optical rotation arises in the liquid crystal and the light is eventually emitted as the light polarized in the direction parallel to the plane of the figure from the antireflection layer 101a. The optical properties of the electrooptical element are changed by the electric field generated by the charges accumulated in the charge holding medium 103 and the change of the optical properties is read by the transmitted or reflected light. The reading with the high accuracy of the molecular level is possible in this way.

Title: Pneumatic radial tire
Inventor: NAKAGAWA SUMUTO
IPC: B60C5/00
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To improve durability by improving corrosion fatigue resistance and an anti-adhesive property of a steel cord by making oxygen partial pressure of filling gas less than a specific percentage. SOLUTION: Oxygen partial pressure of filling gas of a pneumatic radial tire using a steel cord for a belt part and organic fiber for a carcass member is made less than 14%. Consequently, the pneumatic radial tire excellent in durability by improving corrosion fatigue resistance and an anti-adhesive property of the steel cord is provided. Additionally, thickness of an inner liner layer is favourable to be less than 1.2mm. As oxygen partial pressure of filling gas is restricted to be less than 14%, it is possible to prevent intrusion of oxygen to the inside of the tire even when thickness of the inner liner layer 5 is made less than 1.2mm. Additionally, as it is possible to reduce quantity of butyl rubber high in heat build-up, etc., it becomes possible to improve durability as the tire.

Therefore, the full molding covering the rear surface of the substrate can be performed. Furthermore, by setting contact surface of the first supporting member 20 with the metal mold as the line- or point contact, thus, the interface with injected resin becomes long, e.g. P2 , Therefore, moisture resistance can be also improved.
