Title: Loading control system for initial program
Inventor: IKEDA KAZUHIKO
IPC: G06F13/00
Filed: 1985-10-28
Abstract: PURPOSE:To omit the need to give the IPL control information proper to each channel to a CPU by providing a status showing that an initial program loading IPL action is possible to each channel device and at the same time storing an initial program in an external memory device of each channel. CONSTITUTION:In a start mode a CPU1 reads the status of a status information holding part 20-1 to a channel device 3-1 and obtains the information showing that an IPL action is impossible. Then the CPU1 tries to read the status to channel #1 but cannot read it to the end owing to an unpacked state. Then the status of a channel #2 is read out of a status holding part 20-2 of a status channel device 3-2. As the IPL action is possible with this status, an IPL start command is produced to the device 3-2. Receiving this command, the device 3-2 reads the IPL control information out of a disk device 6 and transfers it to a main memory 2. This procedure is applied also to other channels.

Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To provide normal and reverse rotary apparatus capable of being certainly operated, and hardly being damaged even if a stone or the like strikes the normal and reverse rotary apparatus, at a low cost. SOLUTION: This normal or reverse rotary apparatus is the one having a rotary tine installed in the normally and reversely rotatable rotary shaft through a tine seat, and obtained by forming the tine seat into a box shape. The rotary apparatus is obtained by housing the root of the rotary tine in a state slidably contacting with both sidewalls of the tine seat, and rotatably movably installing the rotary tine at the front and rear in the rotating direction by a pivotally supporting pin. The rotary tine post-inclines in the rotating direction by the inertia when the rotary shaft rotates in the normal direction, but the post-inclination posture is kept by allowing the rotary tine to come into contact with the front wall of the tine seat. The rotary tine is almost kept in the upright posture in a free state to the tine seat by the centrifugal force at the time of the reverse rotation.

Title: Speed reduction gear for starting and backing
Inventor: ITO TOSHIBUMI
IPC: B60K17/04
Filed: 1986-10-11
Abstract: PURPOSE:To miniaturize the whole device, and to facilitate the operation of a vehicle, by transmitting the rotation of a starting motor to a starting system by reducing the speed by means of a planetary reduction gear, and transmitting it to the back-driving system of the vehicle by reducing the speed in two stages by means of the front stage and rear stage planetary reduction gears. CONSTITUTION:The output of a starting motor 4 is transmitted to a two-stage planetary reduction gear 63 to reduce the speed in respective stages, and to a starting system the output of the front end is directly transmitted, while to a back-driving system the rear stage output having been reduced in two stages is transmitted so as to drive a vehicle at low speed. Thus, since a high reduction ratio can be obtained with a small size device, a high rotating speed motor being advantageous in the aspects of output characteristics and power consumption can be used as the starting motor, and the whole device can be miniaturized. Further, since the vehicle can be slowly backed by the operation of a starting switch, the operation can be significantly facilitated.

Title: Thin film formation
Inventor: KAJI SHIGEHIKO
IPC: H01L21/318
Filed: 1988-09-29
Abstract: PURPOSE:To deposit a thin film excellent in in-plane uniformity with superior controllability by intermittently introducing gaseous raw materials into a thin film forming chamber. CONSTITUTION:At the time of using an SiN film, etc., as an insulating film, SiH2 and Cl2NH3 are used as gaseous raw materials. The SiN film can be grown by the alternate formation of Si-N bond on a substrate. At a temp. up to 800 deg.C, the velocity of polySi deposition (formation of Si-Si bond) due to thermal decomposition of SiH2Cl2 is slow. By intermittently introducing SiH2Cl2 into a thin film forming chamber, one atom layer of film is grown by a single introduction of SiH2Cl2 if the introduction period is short. subsequently, NH3 is introduced to carry out nitriding. By every introduction of SiH2Cl2 and NH3, the SiN film can be formed. The above intermittent introduction is repeated until the prescribed film thickness is reached. By this method, the thin film having a thickness in the neighborhood of several nanometers can be deposited with superior uniformity and controllability.

IPC: G11B7/135
Filed: 1986-10-13
Abstract: PURPOSE:To obtain an optical head by which the aberration of a lens due to the change of temperature and humidity can be corrected, by providing an optical path length varying means which varies an optical path length between a light source and the above stated lens. CONSTITUTION:A wedge-shaped glass plate 6 is provided at an intermediate position between a semiconductor laser 1 and a plastic objective lens 2. By designing the plastic objective lens 2 as the one to which a glass plate having a thickness of (t) is inserted from the first, and changing the thickness of the glass plate by thickness of 8t, the optical path length from the light source 1 to the plastic objective lens 2 varies by 8t(n-1). Where, (n) is the refractive index of the glass plate. Therefore, by inserting or pulling out the wedge-shaped glass plate 6 in a direction orthogonal to the optical axis of the plastic objective lens 2, it is possible to vary the optical path length between the semiconductor laser 1 and the plastic objective lens 2. In this way, it is possible to always hold the aberration in the best state.

Title: Data processing method and device cad system, data holding method and image forming method
Inventor: TOMITA KENICHI
IPC: G06F17/50
Filed: 1990-09-14
Abstract: PURPOSE:To obtain an easily usable image forming method matched with human's plotting sense or the like by changing the degree of determination of a shape model in accordance with the degree of change in an inputted shape model and distinguishably displaying the display format of the shape model to be displayed on a screen in accordance with the degree of determination. CONSTITUTION:When a designer inputs a shape model to be deleted from an input device 1, a control device refers the degree of determination in the 'existence' of the selected shape model from a storage device 2 and deleting processing is distinguished by the degree of determination. When the degree of determination of 'existence' is high, the control device 3 inquires of the designer about the approval of practical deletion of the shape model, and when the designer approves the deletion, deletes the shape model to be deleted from the storage device 2 and erases the shape model concerned from an output device 3. When the designer rejects the deletion, the degree of determination of the shape model in the storage device 2 is reduced by the control devices 3 and the display width of a line is thined by the output device 3. Thus, optional operation can be attained at the initial stage of design and designer's operability can be improved.
