Title: Buoyancy regulating type float
Inventor: HIRATA MASAYUKI
IPC: A01K61/00
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a buoyancy regulating type float having a structure increased in durability, capable of improving general handleability such as installation or operations to regulate the buoyancy and suitable as an additional float for an oyster raft. SOLUTION: This buoyancy regulating type float is a cylindrical hollow one composed of a polyethylene resin, etc., and having both bulged end faces and is obtained by installing an air supplying and venting valve 14 and a water supplying and discharging opening 15 for regulating the buoyancy on the mutual opposite sides, i.e., the air supplying and venting valve 14 is arranged on the upper side and the water supplying and discharging valve 15 is arranged on the lower side, installing the air supplying and venting valve 14 nearly vertically to a tilted sidewall 13 of a recess 12 so as not to protrude from the float surface without forming a protrusion and without causing any breakage even by rolling or throwing thereof and providing a mooring hole 18 for a rope for moving the float in the sea on the same upper side as that of the air supplying and venting valve 14.  Thereby, operations to open and close the valve 14 and fix the float for regulating the buoyancy can be facilitated and air in the float can be prevented from flowing out because the water supplying and discharging opening 15 is located on the lower side. Furthermore, operations to install an additional float can smoothly be progressed.

Title: Actuator for injector
Inventor: TAKAHASHI TAKASHI
IPC: F02M51/00
Filed: 1987-12-29
Abstract: PURPOSE:To prevent any damage due to unbalanced load of a piezoelectric element from occurring by forming a piston solidly in a hollow tubular spring supporting another end of the piezoelectric element. CONSTITUTION:A piston is operated by a piezoelectric element 33 and pressure in a cylinder chamber 41 partitioned off by the piston is varied whereby fuel injection is controlled. Upon this, an upper end of the piezoelectric element 33 is supported by an actuator housing 31 via an insulator 36 and a cap 34, while a lower end of the element 33 is supported by an inner bottom wall surface 38 of a hollow tubular spring 32 via an insulator 37. Then, this hollow tubular spring 32 forms a spiral slit 40 whereby it is given proper spring elasticity and simultaneously the lower end 32b serves as a piston. With this constitution, since uniform load acts on a lower end face of the piezoelectric element 33, such a possibility that the piezoelectric element 33 may be damaged by unbalanced load is brought to nothing.

Title: Molded surface fastener having continuous rib on reverse
Inventor: TOMOHIRO AKIRA
IPC: A44B18/00
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To prevent tear, keep stickiness of temporary adhesion at sewing time, and prevent local hardening of ultrasonic welding by integrally forming a lattice-shaped continuous rib on the reverse on the opposite side of an engaging surface of a base part sheet. SOLUTION: Tear is prevented by integrally forming a lattice-shaped rib 13 on the reverse face, and particularly, when a surface fastener 10 is sewn, for example, on a fiber fabric or the like, the tear along the most tearable sewing-up line is reliably prevented. For example, a pressure sensitive adhesice is applied to and temporarily installed on the reverse of the surface fastener 10 so as not to move on a surface of a mating member at sewing time or the like. Here, since the lattice-shaped rib 13 is formed on the reverse, many kinds of pressure sensitive adhesives different in pressure sensitive adhesive performance according to a temperature change are dispersively applied in a desired lattice formed of the lattice-shaped rib 13.  Then, viscosity of the pressure sensitive adhesives coping with an ambient temperature of a wide range is exhibited, and always maximum viscosity is secured. In the case of welding by an ultrasonic wave, since pressing force concentrates on the rib on the reverse face, only that fixing force increases but also that brittleness of the whole sheet 11 can be prevented.

Title: Detection of switching and coupling of optical connector
Inventor: KAMIKO KAZUO
IPC: G02B6/38
Filed: 1987-12-30
Abstract: PURPOSE:To prevent the failure of optical connectors and fitting pins by providing detecting and stopping mechanisms so that the pushing of the fitting pins is stopped by stopping the revolution of a motor upon detection of abnormality at the time of pushing the fitting pins into pin holes. CONSTITUTION:A spring 10 is shrunk and the overload exerted upon a 2nd moving base 11 is absorbed when the 2nd moving base 11 stops on generation of the abnormality and only the 1st moving base 7 continues to advance. A shaft bar 8 fixed to the 2nd moving base 11 comes into contact with an abnormality detecting switch 9 fixed to the 1st moving base 7 and the driving of the motor 15 is automatically stopped by the control signal from the switch 9 when the 1st moving base 7 still continues to advance in this state. The pushing of the fitting pins 4 by push pins 12 is then stopped. Overloading of the fitting pins 4 and the optical connectors 2, 3 is thereby prevented.

Title: Room unit for air conditioner
Inventor: KAWASAKI ISAO
IPC: F24F13/20
Filed: 1991-12-19
Abstract: PURPOSE:To reduce noise by respectively forming protrusions having predetermined lengths at upper and lower parts of a stabilizer opposed to a partition plate of a cross flow fan. CONSTITUTION:Protrusions 19, 20 having predetermined lengths are respectively formed at upper and lower parts of a stabilizer 8 opposed to a partition plate 17, etc., for constituting a cross flow fan 12. Accordingly, when the fan 12 is rotated, a gap between the outer periphery of the plate 17 of the fan 12 and a tongue surface 15 of the stabilize 8 disposed near the plate 17 can be intermittently varied. Thus, since a vortex flow generated at the time of rotating the fan 12 can be varied by altering the gap between the plate 17 and the tongue surface 15 of the stabilizer 8, pitch sound of a blase 18 due to the vortex flow can be dispersed. Thus, noise can be reduced without decreasing an air flowing efficiency.

From an input terminal 2, the image information signals of the signal forms such as the VGA, SVGA and XGA, etc., from a personal computer are inputted and the signals are switched to the video signals of the VGA signal form from the NTSC-VGA conversion circuit 11 and are selected. The output signal of a changeover switch 5 is converted into the image signal of the XGA signal form in a VGA-XGA conversion circuit 6 and the signal is supplied to the display means 7.  Thus, image displays are performed for all the image signals inputted from input terminals 1 and 2 by the number of picture element (1024×768) corresponding to the XGA in the display means 7.

Title: Structure of vaneless part of compressor
Inventor: KOBAYASHI KENJI
IPC: F04D29/44
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To suppress generation of the separation phenomenon at a vaneless part by arranging an induction wall projected inwardly along the direction of the inlet air flow at a diffuser on an inner surface of a side wall of the vaneless part which is a connection space between a centrifugal impeller to be driven and the diffuser in a non-rotating condition.
