Title: Bonding of composite material
Inventor: KONDO KATSUMI
IPC: B29C65/00
Filed: 1984-07-24
Abstract: PURPOSE:To produce a material having a complicated shape by a method in which composite materials reinforced with long fibers are bonded together such that the end or side portion of the bundled long fibers of each of the composite materials are pressed to have a projection or a depression and impregnated with a resin for bonding. CONSTITUTION:The projected end portion of a fiber bundle 1 is pressed on a projected or recessed mold 4, and the recessed end face is likewise pressed on a projected mold 5 through a guide 6. Those in the fixed state are then impregnated or coated with a resin liquid and press-molded in a semi-hardened state (pre- preg) from the side of molds 7-9. When the molds 7-9 are removed, the uneven portion of the fibers is fixed without the restoration of the fiber orientation. When combining the unevened end and side portions, the jointed face is widened by the mutual sliding of the fibers and the shearing force is changed to compressive force toward fibers. The bonding strength can thus be raised, designing freedom can be widened, and the manufacture of a material having a complicated becomes possible.

IPC: H04L69/40
Filed: 1994-07-05
Abstract: PURPOSE: To make it possible to reconstitute a system by checking whether a data field generated in specific communication is to be allowed by a communication protocol or inhibited. CONSTITUTION: Respective M and N fields generated from a bus are latched by M and N latches 32, 34 at proper time and respectively sent to a row MUX 35 and a column MUX 36 and unique row and column corresponding to respective fields are selected. A selected output is sent to one input of an output AND gate 38 and a timing window signal (optional) is sent to the other input to generate a clocked error signal. Thus an error check signal for instructing whether a pair of 1st and 2nd data fields are to be allowed by a communication protocol or not is selected, and when the prescribed pair is not allowed by the communication protocol, the selected error check signal stops the specific communication operation.

Title: Optical recording medium and its recording and reproducing device
Inventor: NAGASAKI TATSUO
IPC: G11B7/125
Filed: 1990-06-12
Abstract: PURPOSE:To obtain the optical recording medium of high density information and its recording and reproducing device by modulating the shape and length of a pit in the track direction of the optical recording medium and also in the track widthwise direction as orthogonal to this track direction respectively, the distance between the pits and the distance between a guide track and the pit. CONSTITUTION:Reflected light intensity at a sampling point is observed in two dimensions, i.e. in the track direction and in the track widthwise direction as orthogonal to this track direction at a sampling pitch to satisfy the sampling theorem. By filtering this reflected light intensity with a low pass filter 25 in the two dimensional directions, a distance is modulated in the two-dimensional directions, and two-dimensional position information for a multivalued and recorded pit is obtained. Since this position information is obtained in the way of satisfying the sampling theorem, information of high recording density is obtained from the optical recording medium 16 without depending upon the number of detectors and resolving force of them.

Title: Device number controller
Inventor: ISHIKAWA MASAO
IPC: H02J3/18
Filed: 1981-09-30
Abstract: PURPOSE:To avoid the excessive reactive power, by accelerating the detecting period for the increasing conditions of the number of devices compared with the normal mode in the time band where the load is suddenly increased. CONSTITUTION:The signal TR given from a timepiece device is set at 1 in a period during which the load is suddenly increased. For the control clock TC, the level of the reactive power is compared by a comparator CM1 and in the period of an oscillator. Then a capacitor is added when the increasing conditions is satisfied. The signal TR is set at 0 after the period when the load is suddenly increased, and the synchronism of the control clock is increased by the function of a counter 5 to prevent the increase of the switching frequency of a capacitor which is caused by a short-period fluctuation of the load.

Title: Diffuser structure of centrifugal compressor
Inventor: HERUMASU OO JIYAKOBI
IPC: F04D29/44
Filed: 1984-07-24
Abstract: DIFFUSER CONSTRUCTION FOR A CENTRIFUGAL COMPRESSOR Constant flow width through the last stage diffuser of a centrifugal compressor is maintained against widening by the forces of differential pressure via a diffuser defined between oppositely positioned radial faces of a diaphragm and an annular diffuser plate secured spaced from the diaphragm at the desired with. Enabling the diffuser plate to withstand width deflection and/or enlargement is a pressure balance imposed against the rear surface of the plate as compared to the pressure level incurred from the gas flow at the front surface facing the diaphragm. This is achieved by a sealed radial cavity exposed to the rear surface of the plate and in continuous pressure communication with the front surface through a plurality of vent holes extending therebetween.
