Title: Method for recording information on optical information medium
Inventor: HAMADA EMIKO
IPC: G11B7/0045
Filed: 1993-06-29
Abstract: PURPOSE:To provide a method for recording information on an optical information medium capable of recording the information on an information recordable area of the optical information medium by using a laser with a low output. CONSTITUTION:At the time of recording information on the information recordable area 1B, by a system controller 241, a spindle motor 242 is driven, and an optical disk 1 is rotated at a prescribed rotational speed lower than the speed at the time of reproducing the information, e.g. a linear velocity of 0.6m/s being 1/2 of the linear velocity of a CD standard of 1.2m/s and a write signal length is set double the length at the time of reproducing the information. Further, the effective output of the laser of an optical pickup 243 is set to a prescribed value higher than the value at the time of reproducing, e.g. 1.6mW, and the information is written. Thus, the constitution of an information recording device or an information recording/reproducing device for the optical disk 1 is simplified and the cost is reduced, and the optical disk 1 provided with an information reproducing exclusive area 1A and an information recordable area 1B can be spreaded accompanying that the cost of these devices is made low.

Title: Slide door opening and closing method for automobile
Inventor: TANAKA MASATOSHI
IPC: E05D15/58
Filed: 1986-07-04
Abstract: PURPOSE:To open and close smoothly a slide door which extends up to the roof, by opening the entrance after displacing the slide door outwards in the lateral direction while moving it in the longitudinal direction in the condition of inclining the upper side of the slide door outwards in the lateral direction. CONSTITUTION:By inclining a little a slide door 3 at its lower side as the fulcrum, the upper side of the slide door 3 is displaced above the roof of the car body 1 and the interference with the roof is cut off. The slide door 3 is moved in the longitudinal direction in such a condition, and together with such a movement, it is displaced outwards in the lateral direction to eliminate the interference with the side of the car body 1. After that, by moving the slide door 3 broadly in the longitudinal direction, the entrance 2 is opened. Thus, even though the entrance 2 is opened up to the roof, it can be opened smoothly by drawing the slide door 3 outwards.

Title: Semiconductor container
Inventor: YAMA YOMIJI
IPC: H01L23/02
Filed: 1990-06-15
Abstract: PURPOSE:To prevent a decrease in the functions of semiconductor elements, such as solid image-pickup elements, by providing optical glass for protecting semiconductor elements from outside atmosphere, which glass is formed from a material containing elements which absorb radiation. CONSTITUTION:To protect a solid image-pickup element 1 from outside atmosphere, for example, space environment or atomic reactor environment, radiation resistant glass containing a radiation resistant material, such as cerium oxide or titanium oxide, is fixed by a sealing resin 7, such as an epoxy resin which can be hardened at a low temperature of 200 deg.C or lower, and a solid image- pickup element is housed therein. Glass, whose thickness is made thinner and in which, defects caused in glass, such as striae or air bubbles, are machined into 5mum or less, is used for glass 60. The use of the glass 60 causes substantially no variations in the threshold value of a transistor of a solid image-pickup element before and after gamma rays are irradiated. Since the thickness of a container main body 2 is large, the radiation which enters from the bottom surface and side of the container main body 2 can be substantially blocked.

Filed: 1989-06-21
Abstract: PURPOSE:To attain rapid processing by means of simple constitution by retrieving an inserting position based upon a priority difference value between leading and final queues. CONSTITUTION:In case of inserting a new insertion element into a queue, an operating system 1 calculates a difference between the priority 103 of the leading queue 13 and the priority of the insertion element 1m and a difference between the priority 104 of the final queue 1n and the priority of the element 1m and compares respective differences with each other. Retrieval is started from the element 13 or 1n having a smaller difference to retrieve and determine the inserting position of the element 1m. Thus, the optimum position can be rapidly determined by the simple constitution and rapid processing can be attained.

Title: Frequency multiplier
Inventor: TOCHIGI MAKOTO
IPC: H03B19/14
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent break of an active element due to noise and to keep a high reference signal level by reducing a capacitor capacitance for DC bias cut connected to the inputting side of an amplifier circuit so as to improve noise prevention. SOLUTION: The capacitance of a capacitor C1 for cutting DC bias connected to the inputting side of the C-class amplifier circuit Ap1 of the first stage is set not larger than 100 pF. Consequently, since the noise prevention of the capacitor C1 is high, beak of a transistor Q due to noise is prevented. In addition, it is possible to keep the level of an output reference signal high. In addition, the capacitance of the capacitor C1 is reduced not larger than 100 pF and its size can be reduced. Since the frequency of synchronizing inductors L11, L12 is low, a large inductance is required. Then, a large space of a multi- layered substrate is used for a pattern to increase a cross-sectional area and the large inductance is maintained to reduce the number of volumes of the inductors L11, L12, namely the number of pattern layers is reduced to thin the multi-layered substrate.

Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To instantaneously detect a steering condition even when rapid steering is started, and prevent deterioration of steering operation, by switching the condition to an assist condition based on in the case of a current value in a first threshold value or more or in the case of a change factor of a current in a second threshold value or more or in the case of the both in a standby condition.
