IPC: H01L21/66
Filed: 1988-09-08
Abstract: PURPOSE:To make it possible to provide a new method by which the quantity of donor type impurity concentration is determined by variously changing acceptor impurity concentration NA and the donor impurity concentration ND with respect to a compound semiconductor material, measuring SPL, and obtaining the relationship between relative intensity between the broad light emitting band of the SPL spectrum and a sharp emitted light beam and NAXND. CONSTITUTION:In selective-pair fluorescence (SPL), acceptor impurity concentration NA and donor type impurity concentration ND are variously changed, and the SPL of a compound semiconductor material is measured. The relationship between relative intensity IR between the broad light emitting band of the obtained SPL spectrum and the sharp emitted light beam and NAXND is obtained. The SPL with respect to a semi-insulating semiconductor which is grown without addition of impurities is measured. The IR is obtained from the obtained spectrum, and NAXND is found at the same time. The value of the ND is computed by using the NA that is obtained by another means. In this way, the new method for determining the quantity of the donor type impurity concentration ND can be obtained.

IPC: H01G13/00
Filed: 1989-08-30
Abstract: PURPOSE:To enable discrete detection of the dimension of a component to be detected, irrespective of a dimensional error of another component to e detected, by a method wherein whether the dimension is in the allowable limits or not is detected/by a pair of sensors from a time difference in detection of connecting parts in the opposite ends of the component to be detected. CONSTITUTION:By driving a screw 27 for fixation tightly after adjustment, a fitting wall 12, a slide plate 18 and a slide body 22 are brought into pressure contact with each other and thereby optical sensors 31 and 32 are positioned. When a wire rod 1 is moved in the direction of an arrow, a sensor 31 detects a connecting part 1A on the rear side of a terminal 1B in the direction of movement and a detection pulse is outputted from this sensor 31. At a position to which the wire rod 1 is moved slightly in the direction of the arrow, subsequently, another connecting part 1A on the front side of the terminal 1B in the direction of movement is detected by the sensor 32 and the detection pulse is outputted from the sensor 32. The wire rod 1 is always moved at a prescribed speed of conveyance, and therefore a discrimination between good and bad articles is made by comparing a difference between the times of generation of the detection pulses of the sensors 31 and 32 with a reference time set beforehand.

Title: Water-cooled disc brake device
Inventor: OKOCHI YUKIO
IPC: F16D65/853
Filed: 1992-08-24
Abstract: PURPOSE:To greatly lower the temperature of friction material so as to improve the wear resistance of the friction material. CONSTITUTION:In this water-cooled disc brake device, frictional heat generated to the friction face of friction material 1 is conducted through the friction material 1, high heat conductive material 3 and a pressing member 2 so as to reach the pressing member 2 but not radiated suddenly by cooling water so as to be accumulated in the friction material 1. The heat capacity from the friction face of the friction material 1 to the pressing member 2, however, is higher by the heat capacity part of the high heat conductive material 3 in comparison to a disc brake device without the high heat conductive material 3. Also because of the use of the high heat conductive material 3 higher in heat conductivity than the friction material 1 and the pressing member 2 in order to heighten the heat capacity from the friction face of the friction material 1 to the pressing member 2, the delay of heat conduction from the friction face of the friction material 1 to the pressing member 2 is suppressed to improve the temperature fall of the friction material 1. The wear resistance of the friction material 1 is thereby improved.

IPC: H04L12/42
Filed: 1984-10-24
Abstract: PURPOSE:To avoid an omission of a data and a double receiving of the data by receiving only a frame of a broadcast communication in order to keep a receiving buffer after a specific frame is received under no condition and constructing so as not to receive the frame after the frame of the broadcast communication is received. CONSTITUTION:When one of more than three of data transmission devices 1-4 connected to loop like transmission paths 11-14 carrys out a broadcast communication a command frame is transmitted and then a specific frame inspecting whether a receiving buffer of a transmission end is empty or not is transmitted. When a repeat request of the specific frame is received, this specific frame is transmitted until this repeat is not received, and when this repeat request is not received, the broadcast communication is carried out. In a data transmission device of the transmission end receiving the command frame, if the receiving buffer is not empty when the specific frame is received, the repeat request is transmitted to the transmisison end, and if it is empty, as no response, and when the frame except for the specific frame is detected, the frame is not received but the repeat request is transmitted to the transmis sion end.

Title: Optical type coordinate input device
Inventor: OUCHI JUNICHI
IPC: G06F3/041
Filed: 1987-09-07
Abstract: PURPOSE:To sharply reduce power consumption by driving either one of a light emitting element array and a light receiving element array for an X or Y axis to scan data during the period of no coordinate input operation. CONSTITUTION:When a start signal is applied to a switching circuit 18, an X axis counter circuit 8 is turned to an operating state and the X-axis light emitting element array 2 and the X axis light receiving element array 3 are driven to scan data. When coordinate input operation is not executed during the scanning and a detecting signal is not outputted from an X axis detecting comparator 10, device operation is ended. Thus, when there is no coordinate input operation, only the arrays 2, 3 are driven to scan only once every impression of a start signal. When coordinate input operation is executed during the scanning of the driven arrays 2, 3 and an optical signal is interrupted, a detecting signal is outputted from the comparator 10 and an X axis output control part 11 stores a count value at the time of signal interruption and outputs the count value as a coordinate signal. At the time of outputting the detecting signal, the circuit turns the Y axis system having similar constitution as the X axis system to an operating state. Thus, a Y coordinate signal is outputted from a Y axis output control part 17. Both the coordinate signals are supplied to a microcomputer.

The level of light for each of slave stations 111-11n is measured from that reception level by a reception level measuring part 145, and the adjustment value of the optical level adjusting part 142 is controlled by an optical level control part 144 so that the measured level can become a specified value for each time slot.  A memory 143 stores the identification numbers and optical level adjustment values of the respective slave stations 111-11n and in the case of real communication, the optical level is adjusted corresponding to the optical level adjustment values stored in the memory 143.

Title: Robot
Inventor: ITAGAKI AKIYOSHI
IPC: B25J17/00
Filed: 1988-09-07
Abstract: PURPOSE:To change attitude according to the revolving angle of an arm and to hold the attitude of a work in a constant attitude always irrespective of the revolving angle of the arm by providing a clutch device making the revolving movement of an arm transferable and non-transferable selectively for a rotary axis. CONSTITUTION:When the space between a driven wheel 10 and rotary axis 18 is made in a continuous state by the actuation of a clutch device 21, the rotary axis 18 is rotated by the driven wheel 10 which is rotated according to the revolving of an arm 7. So the rotary axis 18 is rotated by the revolving angle part of the arm 7 and the work held by a hand 17 is held in a constant attitude always irrespective of the revolving angle of the arm 7. When the clutch device 21 is turned off and the link between the driven wheel 10 and rotary axis 18 is released then, the rotary axis 18 becomes impossible to rotate to the arm 7. Consequently, with the revolving of the arm 7, the attitude of the work is changed by this revolving angle part.
