Title: Cleaning method inside rotary drum of concrete mixer vehicle
Inventor: KATSUMORI SHIGEO
IPC: B60P3/16
Filed: 1980-06-16
Abstract: PURPOSE: To improve the effect of cleaning inside a rotary drum by closing the discharge port with a closing member and reversely rotating the rotary drum for circularly running cleaning water inside.  
     CONSTITUTION: A discharge port at the end part of a blade 16 in a rotary drum 7 is closed with a closing member 15 made of sponge or other soft materials. Then, when cleaning water is thrown into the rotary drum main body 7 from a hopper 13 and the rotary drum 7 is reversely rotated (discharge rotation), the cleaning water is pushed up by a blade 9 to rise as an arrow A shows. But, as the discharge port of the drum 7 is closed, a discharge passage 14 between the inside of the opening end of the drum 7 and the outside of a charging cylinder 10 is filled with the risen cleaning water, which is then introduced into the cylinder 10 through gaps 11 and holes 12 of the cylinder 10 and falls to the inner part of the drum 7. Meanwhile, the cleaning water is again pushed up by the blade 9 toward the discharge port of the drum 7 for circulating within the drum 7.

Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To enable a player to practice golf ball hitting in a rhythm of the player him-/her-self, by constituting an automatic golf ball teeing-up device so that the height of a set tee is stored in a memory when a ball confirming sensor detected that a ball is on a ball setting hole on a green mat, and the tee is vertically adjusted to that height from the following time. SOLUTION: When a player rolls a ball B up to a ball setting hole 6 at the beginning of a play, and it is confirmed by a ball confirming sensor of a teeing-up control device that the ball B is on the ball setting hole 6, a tee 8 is elevated to bring up the ball B by the player's pushing the switch of the teeing-up control device with a club. At that time, the tee 8 vertically moves between the highest and the lowest of the tee height, and when the club is detached from the tee the tee 8 stops at that position to set the tee height. The tee height is stored in a memory and the tee 8 is set in the same height from the following time.

Abstract: PROBLEM TO BE SOLVED: To use a resonance box as a speaker by building a vibration excitation device into the diaphragm of the resonance box. SOLUTION: The acoustic signals of various string instruments are supplied to a solenoid 9 of a vibration excitation device attached to every string instrument from an external audio device. The vibrations of the solenoid 9 are transmitted to every resonance box from a vibration member 8 via a resonance box plate body 11 of every string instrument.

The natural frequency is heightened or lowered according to the attachment position of the device 1 despite the same string instrument or the same resonance box. Thus the frequency bands can be complemented with each other among different string instruments.  In such a constitution, the acoustic signals of the external audio device are supplied in parallel to the devices 1 attached to the resonance boxes of a guitar or violin, for example. As a result, the acoustic components of the guitar or violin are generated with emphasis.

Title: Reciprocation type compressor
Inventor: SAKAI TOSHIKAZU
IPC: F04B35/01
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the connecting part of a piston pin with a connecting rod from being abnormally worn out in a reciprocation type compressor. SOLUTION: At the connecting part of a connecting rod 5 with a piston pin 13, since the connecting rod 5 plays a rocking motion relative to the fixed piston pin 13, a fluid film due to lubricant is hardly formed up, and metals are brought into contact with each other at a part of a sliding surface. At this time, the sliding of a non-coagulant film 14 formed over the surface of the piston pin 13 with the metallic contact part of a connection portion of the connecting rod 5, prevents aluminum forming the connecting rod 5 from being coagulated onto the piston pin 13. As a result, an increase in temperature around the connecting part of the connecting rod 5 with the piston pin 13 is reduced, and restraining lubricant from being removed from the surface thereby prevents the surface from being moved to a dry and frictional condition.

Title: Electrostatic chuck
Inventor: ITO ATSUSHI
IPC: H02N13/00
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To reinforce a chuck force by a method wherein a cavity part intervenes between chuck electrode layers of different poles disposed adjacently in the direction of an insulating substrate face. SOLUTION: An insulating substrate 2 constituting an electrostatic chuck 1 is composed of an aluminum nitride sintered compact of a dielectric. Since the insulating substrate 2 chucks simultaneously a plurality of silicon wafers W1 as matters to be attracted, it is formed so as to have an area several times that of the silicon wafer W1. As a surface roughness of a chuck face S1 of the insulating substrate 2 decreases, a Johnson-Rahbeck power increases. The insulating substrate 2 has a multilayer structure, and is formed internally with chuck electrode layers 3, 4, and a heater electrode layer. The chuck electrode layer 3 of a positive pole and the chuck electrode layer 4 of a negative pole are together positioned in a layer close to the chuck face S 1. The respective chuck electrode layers 3, 4 are connected as interlayers to a non-chuck face S2, respectively.  A plus side of a chucking DC power source 5 is connected correspondingly to the chuck electrode layer 3 of a positive pole via a wiring. A shielding material layer 6 intervenes between the different-pole chuck electrode layers 3 and 4.
