Title: Magnetic recording and reproducing drum
Inventor: HONDA HIROHIKO
IPC: G11B15/61
Filed: 1989-06-26
Abstract: PURPOSE:To reduce the oscillation and abrasion of a tape and to improve the fixing accuracy of a head by removing difference in stages between an annular disk base and a rotary head in the width direction. CONSTITUTION:The magnetic recording and reproducing drum consists of the rotary drum 2 to be rotated unitedly with the rotary head 1, a fixed drum 3 and the annular disk base 4 for fixing the rotary head 1. The rotary head 1 is fixed to the base 4 so as not to generate a difference in stages in the width direction and the thickness of the base 4 is made coincide with that of the head 1. Thus, the projected length of the base 4 from the outer periphery of the drum 2 is made equal or slightly shorter to/than the projected length of the head 1 and the head 1 is fixed to the base 4 so as not to generate a difference in stages in the width direction. Consequently, the oscillation and abrasion of the tape can be reduced and the fixing accuracy of the rotary head 1 can be improved.

Title: Drive connection device for four-wheel drive
Inventor: INOUE MASAHIRO
IPC: B60K17/348
Filed: 1990-06-21
Abstract: PURPOSE:To reduce work mandays and assembling mandays and make a device compact by providing vane push-up check valves which only allow in-flow of oil to connection grooves in a pair of connection passages to guide the oil pressure in a pair of oil passages to the connection grooves only respectively. CONSTITUTION:When a rotation speed difference is generated between front and rear wheels, a relative rotation is generated between a casing 1 and a rotor 30. When a relative rotation occurs in the direction of a white arrow, actuating oil in a pump chamber 40 is rotated from a suction discharge port 41 to a suction/discharge port 42, and the pressure is decreased at the aperture part of the suction/discharge port 41, while the pressure is increased at the aperture part of the suction/ discharge port 42. The pressure in an oil passage 11 connected with the suction/discharge port 41 becomes negative to close a vane push-up check valve 6 installed in a connection passage 45 connecting the oil passage 11 with a connection groove 30b. The pressure in an oil passage 12 connected with the suction/discharge port 42 becomes high to release a vane push-up check valve 7 in a connection passage 46 connecting the oil passage 12 with a connection groove 30b. The high pressure in the pump chamber 40 is guided toward the bottom part side of a vane 30a, and the vane 30a is pushed to the inner circumferential surface of a cam ring 31.

Title: Back-pressure control type exhaust gas recycle apparatus
Inventor: YAMAZAKI TATSUMI
IPC: F02D21/08
Filed: 1978-12-21
Abstract: PURPOSE: To improve operating efficiency and fuel economy with the secure closing of EGR valve during a high-load period of the engine by always conducting load pressure generated upstream of throttle valve, into a cell at an opposite side of diaphragm in EGR valve partitioned by the diaphragm.  
     CONSTITUTION: If throttle valve 6 is opened to provide such an opening as to be made by its edge overlapping port 7, negative pressure is transferred to diaphragm chamber 44 of EGR valve 4 through pressure-adjusting valve 5. Then, if pressure differential between the said negative pressure and negative pressure in a cell 46 reached a higher level than predetermined, valve body 42 is heaved from valve seat 45, resisting spring 43. Thus exhaust gas is recycled from exhaust manifold 3 to suction manifold 2. In this case, when throttle valve 6 is opened larger past port 7, it is feared that negative pressure might be increased and EGR valve 4 be opened by a set pressure of spring 43, if the cell 46 is exposed to the atmosphere. However, negative pressure in port 8 upstream of throttle valve 6 is transferred to the cell 46. Therefore, the valve body 42 is forced into the direction of closing a valve.

CONSTITUTION:An uneven part A is formed by arranging the groove 6 extending in the axial direction in the peripheral direction on the outer peripheral face of a metallic shaft 1. A jointing layer B is formed as well by depositing a brazing filler metal on the outer peripheral face of the metallic shaft 1 in adjoining to the uneven part A. A metallic sleeve 2 is then inserted over the metallic shaft 1 and by inserting the end part of metallic shaft into a die 8, the metallic sleeve 2 is supported on the die 8 and a deformation checking die 3 is fitted over the outer side of the metallic sleeve as well. Then with heating of the metallic sleeve 2 by electrifying a high frequency heating coil 5, the joining layer is melted to seal the engaging part of the shaft 1 and sleeve 2. Simultaneously with pressing of the end face of the sleeve by a pressure jig 4, the sleeve 2 is squashed, biting into the uneven part A of the shaft 1 and the shaft 1 and sleeve 2 are mechanically bonded.

Title: Four wheel drive device
Inventor: KITAO YUICHI
IPC: B60K17/348
Filed: 1986-07-11
Abstract: PURPOSE:To reduce tire wear and enhance brake performance by employing a clutch part for disconnecting power transmission either when an output part runs at a high speed during driving or when an input part runs at a high speed during braking. CONSTITUTION:When driving in a straight line driven by an engine, a front wheel is urged by a rear wheel and tends to rotate faster than a set speed. In that case, clutch teeth 23 and 30 are disengaged from each other and the front wheel becomes in a freely rotating condition. Namely, the rear wheel only is driven while the front wheel rolls along the ground surface producing no tire wear due to slip. When using engine brake, on the other hand, power is transmitted from both side parts 28 and 29 to a central part 27. At this time, a rear power transmission shaft 5 tends to rotate at a lower speed. In that case, engine brake works on both front and rear wheels as the side part 29 is fixed.

Title: Method of calculating air injection quantity into sewage force feed pipe
Inventor: INOUE SHIZUO
IPC: E03F7/00
Filed: 1991-07-04
Abstract: PURPOSE:To inject a necessary quantity of air by preliminarily making a model of oxygen consuming speed in a sewage in a determined time band, and determining oxygen consumed quantity in each time band from the residence time of the sewage in a pipe from the start point to the end point. CONSTITUTION:A sewage force feed pipe 3 is buried in the ground with a pump chamber 1 as a start point, and a sewage pump 4 is connected to the force feed pipe 3 through a valve 5 and a flowmeter 6. A compressor 7 for injecting air is connected to the force feed pipe 3 through an air pipe 8. In the pump chamber of the start point of the force feed pipe 3, oxygen consuming speed of a sewage is first measured to form a model. The oxygen consumed quantity in 1l of the sewage is determined every time band of the residence time in the pipe from the pump chamber 1 to a manhole 9. Then, an air quantity slightly exceeding the oxygen injection quantity determined from the sewage quantity and the oxygen consumed quantity is calculated, and air is injected. Thus, the sewage is prevented from being anaerobic atmosphere in the force feed pipe 3, and the formation of hydrogen sulfide can be prevented.

IPC: G03G15/20
Filed: 1988-07-02
Abstract: PURPOSE:To improve image resolution, to eliminate the need for the processing of exhausted toner, and to lengthen the life of a photosensitive body by developing toner onto a thin film stuck on the photosensitive body, and then transferring and fixing it onto a sheet by using a heating roll. CONSTITUTION:The photosensitive body is comprised of an electrically conductive substrate 1c, electric charge generating layer 1b, and electric charge shifting layer 1a; and said photosensitive body 1 is uniformly and negatively electrified by means of a contact electrifier 2a connected to a DC power source 2b. An exposing device 3 image-exposes the photosensitive body 1, and electron/hole is generated on the layer 1b. The hole ascends the layer 1a with the aid of the electric field of surface charge, and lowers surface electric potential; thereby an image part B and an image nonforming part W are created. At the same speed as the moving speed of the photosensitive body 1, the film 4 is moved so that it adheres to the photosensitive body 1; development onto the film 4 is performed through the use of toner 20a held on the surface of a non-magnetic sleeve 5a containing a magnet 5b. The film 4 is moved between the heating roller 11 and pressure roller 12, and transfer and fixing is ultimately performed onto the paper 14.
