Title: Dew condensation preventive device
Inventor: NONAKA SHIGENOBU
IPC: F24F7/007
Filed: 1990-09-17
Abstract: PURPOSE:To prevent DEW condensation definitely by controlling the operation of an air conditioning ventilation means based on a control target temperature and a dew point. CONSTITUTION:A temperature sensor 1 detects a control target temperature T while a temperature sensor 2 detects a control target humidly H in a dew point computation section 3, which computes a dew point D based on the detected temperature T and the detected humidity H. A comparison detection section 4 compared the computed dew point D with he detected temperature T and outputs a comparison detection signal in the case when the control target satisfies the condition of dew condensation, say, D=T. An operation control section 5 receives this output comparison signal and operates, for example, controls the operation of a ventilation fan 6 as a ventilation means. This structure of the dew condensation prevention device makes it possible to prevent dew condensation of a control target definitely without setting any control target value.

Title: Insulated trolley line connector
Inventor: KINOSHITA HIROMI
IPC: H01R4/34
Filed: 1984-11-22
Abstract: PURPOSE:To reduce the number of bending processes of a conductor as well as to shorten a span of working time, by installing each bending piece being projected out of a cover and folded in an almost near right angle, while installing an electric conductor joint having conductor insert holes where these bending pieces are inserted in a state of being superposed on each other. CONSTITUTION:Both insulated trolley lines 1 are made up of cutting away a cover 13 at a spot of the specified distance l away from the end face, and makes the end face of each conductor jut out of the cover 13. And, this conductor projecting pat is bent in an almost near right angle and set down to each bending piece 12a. These bending pieces 12a are made to pass through each conductor insert holes at both upper and lower pieces and each conductor locking screw 28 being screwed in an intermediate piece part of these joint bodies 27. Both bent pieces 12a are made to pass through the conductor insert hole 26 of the joint body 27 in a state of being superposed on each other, and clamped in the superposed direction and locked with each conductor locking screw 28. Therefore, the number of bending processes of the conductor 12 is few, thus working time is reduced.

Title: Integral shroud vane
Inventor: MASUZAWA CHIKANORI
IPC: F01D5/22
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To prevent the pressure loss due to wake and peeling at a front edge and a rear edge of a shroud and lowering of cascade performance by having a roundness in a tip of a front edge of an upstream side shroud and a rear edge of a downstream side shroud, and gradually reducing the plate thickness of the rear edge toward a tip thereof. SOLUTION: A front edge 3a of an upstream side shroud 2a and a rear edge 4b of a downstream side shroud 2b are formed into the shape having roundness at a tip thereof. In the front edge 4a of the downstream side shroud 2b, an acute angle is eliminated so as to form a round shape, and plate thickness is smoothly reduced toward a tip of the rear edge 4b. Thickness of the downstream side shroud 2b is formed smaller than the thickness of the rear edge 3b of the upstream side shroud 2a. With this structure, peeling at the front edge 3a is prevented and restricted, and the front edge 4a of the downstream shroud 2b is not projected to a flow 5, and peeling by the front edge 4a of the downstream side shroud 2b is thereby prevented.

Abstract: PURPOSE:To enable manually the characteristics of a suspension system equipped with variable damping force to be adjusted buffer by providing a valve body in a piston rod of the buffer to adjust the characteristics of both buffer and bushing with the operation of the valve body. CONSTITUTION:When an operative means 122 is operated by a driver or sensor signal to rotate a valve body 110, a hole (not shown) in a piston rod 26, further holes 60 and 62 communicate to a small bore path to vary the damping force of a shock absorber 12. And fluid chambers 80, 82 in a bushing 16 communicate to each other to vary also the spring constant of the bushing 16. And the communicating bore is increased as the rotational angle of the valve body 110 is increased, so that the damping force of the shock absorber 12, the spring constant and damping force of the bushing 16 are reduced. By this constitution can be manually optimized the damping force and spring constant.

Filed: 1983-12-26
Abstract: PURPOSE:To largely reduce the channel leakage current by forming the same conductive type channel cut layer as a semiconductor substrate on the surface of the substrate exposed at the outside of a mesa groove of a mesa type semiconductor device. CONSTITUTION:An N<+> type layer 2 is formed on the first main surface of an N<-> type substrate 1, a P<+> type layer 3 is partly formed on the second main surface, and an N<+> type channel cut layer 4 is formed to surround the layer 3.

Title: Rewinding and winding device for strip continuum
Inventor: MIYAZAWA SHOICHI
IPC: B65H23/198
Filed: 1986-10-20
Abstract: PURPOSE:To make a strip continuum smoothly windable and vice versa, by detecting a height position of the strip continuum when it is conveyed, with a sensor, and making it control a drive mechanism conveying and driving the strip continuum at all times. CONSTITUTION:Since a strip continuum 14 comes to a state of being tensed or slacked by equilibrium between the speed rewound out of a reel 10 and the speed drawn by a working device or the like, a height position of the contin uum 14 is monitored and a revolving speed of the real 10 is adjusted for the end. That is to say, when the continuum 14 goes up and reaches the position of a first sensor 23, the revolving speed of the reel 10 is increased, yet much more of the continuum 14 is rewound and it is made to go down, making it so as to be slacked, and when the continuum 14 is slacked and reached to the position of a second sensor 24, the revolving speed of the reel 10 is slowed down, making the continuum 14 go up. Thus, a position in the vertical direction of the continuum 14 rewound out of the reel 10 is detected, and the revolving speed of the reel 10 is adjusted so as to cause the continuum 14 to move up and down between two sensors 23 and 24.

Title: Semiconductor integrated circuit
Inventor: KOMAKI MASAKI
IPC: H03K19/0175
Filed: 1990-09-19
Abstract: PURPOSE:To prevent noise from being generated at a power source without lowering load driving ability by charging the capacity load of an output buffer circuit at the time of outputting H level from an inverter in the final stage and discharging the capacity load of the output buffer circuit at the time of outputting L level. CONSTITUTION:When an output signal Vout is changed from the L level to the H level, a capacity load Lc is charged by operating a spare circuit 3 before the operation of an inverter 2 in the final stage. When the signal is changed from the H level to the L level, the electric charge accumulated at the capacity load Lc is absorbed before the operation of the inverter 2 in the final step. Thus, without lowering the load driving ability, the output buffer circuit can prevent noise from being generated at the power source.
