Title: Cooling method for aggregate
Inventor: SATO HIDEAKI
IPC: B28C7/00
Filed: 1989-07-13
Abstract: PURPOSE:To cool aggregate efficiently with inexpensive equipments, by putting constituent particles wetted with water into an air flow. CONSTITUTION:Atomized water fed through a water sprinkling pipe 18 flows down in order to the lower part from the upper part of aggregate 12 stuck to the surface of constituent particles each of the aggregate 12 for wetting them. When air is fed to the aggregate 12 from a blower in the direction of an arrow through a hole 20 of a board member during feed of the water or after the feed of the water, the constituent particles of the aggregate 12 are put in an air flow and the water wetting the surfaces of the constituent particles each is evaporated by coming into contact with the air flow. Since a cooling effect of the constituent particles each of the aggregate 12 is the highest when the whole constituent particles are put within the air flow under a state where the whole surface of them is covered appropriately with a thin water film, a quantity of sprinkling water, continuing time of sprinkling, a quantity of blasting air and laminar flow pressure corresponding to grain size are established appropriately.

Title: Power breaker
Inventor: KOYAMA EISUKE
IPC: H01H9/54
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To interrupt power to a test device through a lower apparatus disposed closely to a test device by providing a machine side breaker and a first breaker arranged between a machine side breaker and the test device so as to interrupt the power to the test device through the control of a controller and the test device. SOLUTION: When a command to start a test is outputted from an upper controller 3, power is supplied to a test device 1. A controller 2 is always communicated with the device 1, and when the communication therebetween is stopped, it is determined that there occurs abnormality in the device 1, then a first breaker 10 and a second breaker are immediately operated to interrupt the connection with a power supply 4. Accordingly, even if there occurs failure in the breaker 10 or 11, the supply of power is immediately and surely interrupted. Moreover, the device 1 monitors its condition at all times, and operates the first breaker 10 immediately when any abnormality is detected to thereby stop the supply of power. Consequently, even when there is abnormality in the controller 2, the device itself operates the breaker 10 to stop the supply of power immediately and surely in this way.

Title: Classifying apparatus
Inventor: KAWADA AKIRA
IPC: B07B7/083
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a classifying apparatus capable of holding stable classifying accuracy regardless of the quality (moist degree) in spite of a low cost. SOLUTION: The raw material supplied to a second raw material supply pipe 201 is separated into a coarse powder 51a and a fine powder 51b before dispersed by a dispersing plate 203 and, therefore, the classifying accuracy of a classifying apparatus can be enhanced. Since the raw material 51 supplied through the second raw material supply pipe 201 is dried, the coarse and fine powders 51a, 51b bonded to each other can be made easy to separate and it can be prevented that the once separated coarse and fine powders 51a, 51b again adhere to each other. That is, stable classifying accuracy can be held regardless of the quality (moist degree) of the raw material 51.

Title: Apparatus for detecting flight speed of ink droplet
Inventor: KIMURA MASATOSHI
IPC: B41J2/125
Filed: 1983-09-27
Abstract: PURPOSE:To detect the flight speed of an indivisual ink droplet, in an ink jet recording apparatus, by processing the electrical change of a charging electrode with the flight of a charged ink droplet. CONSTITUTION:The ink droplet 3 injected from a nozzle 2 is charged by a charging electrode 5 and flied toward an ink droplet adhering body 10 as a charged ink droplet 3. As this ink droplet 3 approaches the charging electrode 5, an induced current is flowed to the charging electrode 5. A detection circuit 9 processes the change in the induced current flowing through the charging electrode 3 and respectively detects time when the ink droplet 3 passes the charging electrode 5 and time required in adhering the ink droplet 3 to the adhering body 10. Subsequently, the flight speed of the ink droplet 3 is calculated on the basis of both detected times. By this method, the flight speed of the individual ink droplet can be detected.

IPC: G11B25/04
Filed: 1995-07-17
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording and reproducing device having high reliability and small-sized constitution without breaking distributing wires on a flexible substrate by projecting the flexible substrate including a circular- arcuate part from an opening part of an optical deck chassis cover. SOLUTION: The opening part 11b is provided on a cover part 11a of an optical deck chassis 11 to be outside the diameter of an optical disk 10. When laser light of an optical pickup 1 comes in the vicinity of a position of irradiating an outer circumferential part of the optical disk 10, the flexible substrate 4 is also moved, and its circular-arcuate part 4a and its neighborhood are projected out of the opening part 11b, so that they are not brought into contact with the lower surface of the optical disk 10. When the laser light comes in the vicinity of a position of irradiating an inner circumferential part of the optical disk 10, the circular-arcuate part 4a is housed in the optical deck chassis 11. Consequently, stress does not concentrate on the circular-arcuate part, thus obtaining the device having high reliability without breaking distributing wires of the flexible substrate.

Title: Bunker raking device
Inventor: TAKEU YOSHINAGA
IPC: A63B57/50
Filed: 1995-06-22
Abstract: PURPOSE: To make sand accumulated on the upper surface of the warped plate dropped spontaneously, and quickly deal with wear of multiple number of fork blades by executing positioning selected from an inclined working position of a warped plate and a suspended position thereof with greater inclination angle than that of the working position. CONSTITUTION: When a single bunker rake is lowered, a warped plate 27 rotates centering around a support pin 29, wherein an inclined position in a working condition is determined automatically as a result of the upper surface of an abutting plate 28 on both ends of the pin abutting onto a first stopper face 26a of a positioning stopper 26. Thus, sand in front of the warped plate 27 flows smoothly backward, keeping the sand in front on the warped plate 27 away from remaining. When the single bunker rake is raised upon finishing the work, the warped plate 27 rotates until the upper surface of the abutting plate 28 on both ends abuts onto a second stopper face 26b, and stops at an inclination angle greater than in the working condition.  Thus, the sand accumulated on the upper surface of the warped plate 27 drops of from the rear end of the warped plate 27 without remaining on it as it has been.
