Title: Stirring apparatus
Inventor: YANO YOSHIO
IPC: B01F27/94
Filed: 1986-01-18
Abstract: PURPOSE:To improve the recirculation efficiency of an object to be treated in a stirring tank and a stirring cylinder, by forming an inner hole having an inclined part, which is opened in a tapered form at the upper and lower parts thereof so as to be respectively directed upwardly and downwardly, in the stirring cylinder. CONSTITUTION:The object to be treated going beyond the upper edge of a stirring cylinder 29 to enter the inner hole 39a of the stirring cylinder 29 collides with a baffle plate 30 to move downward through the inflow port 48 provided to the intermediate part of the inner hole 39a. At the inclined part 40a provided to the upper part of the stirring cylinder 29, the object to be treated collides with the baffle plate 30 to move toward the inflow port 48 while generating a violent turbulent stream. Therefore, no remaining or stagnation of the object to be treated is generated on the inclined part 40a. Further, because the inflow port 48 is narrow, the flow speed of the object to be treated is high and, there fore, on the inside surface 50 thereof, the stagnation or remaining of the object to be treated is eliminated.

Title: Video disk player
Inventor: YAMAMOTO TAKAO
IPC: G11B27/10
Filed: 1984-01-20
Abstract: PURPOSE:To make a player main body stop its reproducing action automatically at the time of completion of reproduction of an object chapter by utilizing a mute signal outputted at the time of chapter reseach. CONSTITUTION:In case only an object chapter is desired to reproduce, a mode selecting switch 1 is connected to a contact point side (a). Then a mute signal (high level) is applied to a terminal 10, and a player main body is brought into the repeat reproduction condition. Thus, after the player main body has accessed to the object chapter and reproduced it searches a head of the chapter because of the repeat reproduction condition. At this time, pictures and signals become the mute condition again. Namely, a mute signal turns out to be a high level again from a low level, and by this level change, the 2nd monostable multivibrator 6 operates and outputs a pulse signal showing completion of reproduction. By adding this pulse signal to a switch 9, the player main body decides completion of reproduction and a reproducing action of a disk is terminated.

Title: Specific position engaging clutch
Inventor: FURUTA HIDETSUGU
IPC: F16D11/00
Filed: 1992-01-22
Abstract: PURPOSE:To prevent an abrasion of the engaging part, and an impossible clutch engagement owing to an accompanied rotation, by using a rolling bearing as a guide member, when one side member is rotated and it is engaged to the other side member at a specific position. CONSTITUTION:A clutch 11 consists of a rolling bearing 13 held by a pin 12 projecting at a specific part on the side surface 3a of a driving gear 3 which is impossible to rotate and impossible to slide in the axial direction to a driving shaft 2; a specific notch 14 on the side surface 5a of a follower shaft 5; and an air cylinder to rotate a change-over shaft 18 which holds an eccentric shaft 17 fitted to the groove 15 of the gear 3. The bearing 13 is pressure-contacted to the side surface 5a and rotated by the air cylinder, the gear 3 is engaged with an inner gear 6 at the same time to fit to the notch 14, and the clutch 11 is engaged at a specific position so as to transmit the motive power to the follower shaft 5 from the driving shaft 2. Since the rolling friction coefficient when the bearing 13 rolls with the side surface 5a is very small, the abrasion of the members 13 and 5a is very small. Also since the friction coefficient is low, the follower shaft 5 is not accompanied to rotate, and the clutch is engaged surely.

Title: Scanning position detector for light beam scanner
Inventor: KATSUMARU YASUSHI
IPC: G01B11/00
Filed: 1982-01-26
Abstract: PURPOSE:To detect the scanning position of a laser beam more accurately by a detector wherein a photo detector is arranged for a light beam which enters between electrodes spaced by a given distance, and the electrodes are connected to a comparator so as to obtain a signal proportional to the center position of light intensity distribution. CONSTITUTION:When a laser beam scans a rectangular photo diode 1, output from a detection electrode 1a is amplified at 3 to assume a waveform Wa and output from a detection electrode 1b is amplified at 4 to assume a waveform Wb. Both waveforms become symmetrical about an axis passing through a point (r) where they intersect. When the laser beam scans the diode 1, amplified outputs are compared with each other in a voltage comparator 5. Thus, when the  center of the diode 1 is irradiated, there occurs no difference between both amplified outputs and the output from the comparator 5 becomes zero. It is thus possible to detect the scanning position of the laser beam accurately.

Title: Disk device
Inventor: KISHI YUJI
IPC: G11B17/043
Filed: 1994-01-31
Abstract: PURPOSE:To reduce the thickness of a disk device by using a reset spring which has only the expanding/contracting actions by its shift secured by means of a slider of small plate thickness and a linear motion and then placing the reset spring at the side part of the disk device. CONSTITUTION:A reset spring 16 serving as an energizing member of a slider 12 is placed in parallel to the cartridge loading direction A in a space which is regulated by a stage part 9a of a chassis 9. Then both end parts of the spring 16 engage a 1st spring hook piece 16a of the slider 12 and a 2nd spring hook piece 16b of a guide plate 14 respectively. Then the spring 16 linearly expands and contracts only in the cartridge loading/ejecting directions (arrows A and B) according to the shift of the slider 12. When the plate thickness of the slider 12 is reduced and the shift of the slider 12 is limited in a linear motion by the plate 14, the spring 16 has only expanding/contracting actions. Thus the position of the spring 16 is not changed and therefore a dead space is reduced.

Title: Twin type blower
Inventor: TOKUNAGA KOUJI
IPC: F04D25/16
Filed: 1980-01-29
Abstract: PURPOSE: To abolish a conventional emergency blower by a method wherein two volute blowers which have half the necessary output of blowers in the range of low load of an engine are housed in a common casing and emergency starting is made possible by the blower on one side.  
     CONSTITUTION: A pair of volute blowers 9A, 9B are composed of electric motors 8A, 8B and a volute propeller fixed to their rotary shaft. Each of the these volute blowers has half the output in the range of low load of the engine. For example, if a low load output is given by 60KW, 30KW output is specified to each of the volute blowers. Therefore, in the starting time and in the low load range two volute blowers 9A, 9B are used simultaneously to compensate scavenging capacity and scavenging pressure within the range up to 60KW (50% load or less). Thus, in an emergency, the blower can be started by the output of one blower on one side and conventional emergency auxiliary blowers will become unnecessary.
