Title: Data communication system using broadcast and barrier
Inventor: IWASHITA HIDETOSHI
IPC: G06F15/80
Filed: 1989-09-11
Abstract: PURPOSE:To perform the broadcast and barrier operation in a quick and stable way and with small numbers of steps and packets by performing an informing operation in three steps, i.e., the broadcast, the butterfly barrier, and the end information. CONSTITUTION:The broadcast 1 is carried out in a tree shape between a processor PE and all other PEs, and the butterfly barrier 2 is carried out mutually between the PEs that received the broadcast 1 lastly. Then the PE that joined the barrier 2 gives the end information 3 to all PE which did not join the barrier 2. That is, the information is carried out in three steps, i.e., the broadcast 1, the barrier 2, and the information 3. Thus the broadcast 1 and the barrier 2 can be performed in a quick and stable way and with small numbers of steps and packets.

Filed: 1992-08-11
Abstract: PURPOSE:To reduce the number of parts of a control system by a method wherein a microcomputer is employed in the control system of an indoor machine to control the ventilating fan of the indoor machine by the microcomputer. CONSTITUTION:The objective rotating number of a ventilating fan for an indoor machine is obtained in a microcomputer 12 and a signal for driving a transistor 3d is outputted while base signals for driving other transistors are outputted at the same time. In this case, the present rotating number of a DC brushless motor 1 is operated. When the present rotating number is smaller than the objective rotating number, the transistor 3d is put ON/OFF and rectified voltages are switched, however, the ON-duty ratio of a chopping signal for driving the transistor 3d is increased. When the present rotating number is larger than the objective rotating number, the duty ratio of the chopping signal for driving the transistor 3d is reduced down and the level of a voltage, supplied to a switching circuit 4, is reduced. According to this method, the rotating number of the DC brushless motor 1 is reduced.

Title: Semiconductor light emitting equipment
Inventor: KONO KENJI
IPC: H01S5/00
Filed: 1990-09-06
Abstract: PURPOSE:To improve luminous efficiency of laser, without degrading the light signal intensity, by installing a reflecting mirror on the periphery of a convergent lens, reflecting superfluous laser output light which does not participate light signal formation, in specified directions, making said light enter a photo detector, and monitoring the laser output. CONSTITUTION:A rear reflecting surface 5 of the resonator of a semiconductor laser 1 is provided with an RF coating which makes the reflectivity nearly 100%, and the laser light is outputted only from the front surface. A convergent lens 2 of quartz is arranged on the front center axis of the laser output light, and a reflecting mirror 3 is installed so as to surround the convergent lens 2. Spread of a part of the laser output light from the center axis is rather large, so that said part of the light does not enter the convergent lens 2 but is reflected by the reflecting mirror 3. The reflected light enters a photo detector 4, for which, e.g. a PIN photodiode is used. Since a sufficient output current is generated in the PIN photodiode by non-coupled light which does not enter the convergent lens, a superior monitor signal with sufficient S/N ratio can be obtained. Thereby the monitor signal can be obtained without degrading the light signal intensity.
