Title: Forced air supply type combustion device
Inventor: INOUE HIROSHI
IPC: F23D14/02
Filed: 1983-02-09
Abstract: PURPOSE:To keep the distribution of secondary air uniform and yet prevent premixture from leaking to the secondary air side by a structure wherein a secondary air chamber is partitioned by the projections arranged in the secondary air chamber into the same number of chambers as the number of secondary air passages. CONSTITUTION:A secondary air chamber 8 is partitioned by projections 26 into three chambers 8a-8c so that the instability of the distribution of the secondary airs in the respective chambers 8a-8c to the flow holes 10 provided in the respective chambers 8a-8c due to the flow speed distribution within the respective chambers 8a-8c is dissolved. Accordingly, even when the flow rate of the secondary air changes, the distribution ratio of the quantity of the secondary air to the flow holes of the respective chambers 8a-8c can be kept constant. In addition, because burners 2 are supported by engaging both the heads 26a of rail-shape projections 26 integrally formed with a burner main body 1a and the engaging parts 27 provided on the top of the burners 2 with each other, the trouble to bolt the burners to the burner main body is saved and at the same time the leakage of premixture through the threaded holes of bolts to the secondary air side can be prevented.

Title: Drive device for motor
Inventor: TANIMOTO YASUFUMI
IPC: H02P8/16
Filed: 1982-02-10
Abstract: PURPOSE:To drive a motor at a high speed, to reduce the temperature rise and wasteful current consumption by flowing a phase current through other phase when a certain phase is interrupted in excitation. CONSTITUTION:When an input DT1 to a transistor 22 becomes ''H'', the transistor 22 is conducted, thereby exciting a coil 20. Then, when an input DT1 becomes ''L'' and an input DT2 becomes ''H'', the transistor 22 is interrupted, and a transistor 24 is conducted. Thus, a coil 21 is energized. Since the coils 20, 21 are inductively coupled, when the phase current of the coil 20 is interrupted, the phase current of the same direction flows also through the coil 21 by the induced electromotive force. This phase current commutates the loop of the coil 21, a power source 23 a diode 26 and the coil 21. At this time, in the circuit having the coil 20, the diode 25 becomes in the direction for reversely biasing the diode 25, no phase current flows.

Title: Head clash preventive method and preventive device for stationary disk device
Inventor: CHIGUSA EIJI
IPC: G11B21/22
Filed: 1993-02-08
Abstract: PURPOSE:To avert the damage of recording medium at the time of moving cat a magnetic head to the recording medium by accelerating the rotating speed of a magnetic disk to a specified speed or above and moving the magnetic head to the recording medium. CONSTITUTION:A driving control circuit 31 outputs a command 32 to increase the rotating speed of the magnetic disk 3 to an overspeed temporarily exceeding the specified speed to a rotation control circuit 12 when the start command 22 of the disk 3 is given at the time of resetting the magnetic head 5 from above a holding base 10 to the recording medium 3a of the magnetic disk 3. The circuit 12 controls the rotating speed of the disk 3 so as to accelerate the rotating speed at one time to the overspeed at one time and to return the rotating speed to the specified rotating speed in ordinary operation after holding the overspeed for the prescribed period of time. As a result, the head 5 is temporarily increased in floating pressure and can maintain the floating height by overcoming the inertia to fall from the holding base 10 and, therefore, the damage of the recording medium 3a by contact of the head 5 with the disk 5 and the consequent destruction of the recording data are averted.

Abstract: PURPOSE:To ensure the free selection of the electronic computers of the remote side for data communication by reading the protocol information out of a memory device after reception of the input designated for selection/connection of the remote side and sending the protocol information to the computer of the remote side as a calling packet. CONSTITUTION:When an access is given to an electronic computer C of a different packet form, a remote side selection/connection control part 15 reads the protocol information out of an auxiliary memory device 14 after receiving the input designated for selection/connection of the remote side. Then the part 15 sends the protocol information to a computer C as a calling packet. The computer C sends back a call end packet after its own part 15 reads the protocol information out of its own auxiliary memory device 14 and the relevant preparation is through. When said call end packet is received, this reception is informed to a data transfer control part 10 and the communication is started. Thus it is possible to freely select one of many electronic computers of the remote side.
