Patent JP-H078789-A (JP)
Title: Multitubular heat exchange type reactor
Inventor: TAKAHASHI HISAO
IPC: F28D3/02
Filed: 1993-06-24
Abstract: PURPOSE:To increase the contact efficiency of gas and liquid by constituting an ejector or an ejector nozzle for spouting reaction liquid, a throat for mixing gas and liquid and a diffuser for forming the reaction liquid wherein gas is mixed with liquid into a falling film on the internal wall of a pipe and installing a plurality of ejectors in correspondence with the number of the pipe for heat exchange. CONSTITUTION:Reaction liquid is spouted through the respective ejector nozzles 41 while keeping flow velocity. Gas contributing to reaction in the case of passing through throats 42 is sucked and caught from a gas introduction port 3. First contact of gas and liquid is performed in the parts of the throats 42. Then the reaction liquid wherein gas is mixed with liquid is blown against the internal walls of pipes 51 for heat exchange by diffusers 43 and allowed to flow down along the internal walls thereof. While reaction liquid flows down in the internal walls of the pipes 51 for heat exchange, furthermore a second contact of gas liquid and heat exchange are simultaneously performed. In other words, contact action is promoted by contact of gas and liquid in two stages and the mass-transfer rate of gas contributing to reaction into liquid is increased and velocity of dissolution of gas into liquid is increased. Therefor reaction velocity is made rapid because the mass-transfer rate of gas does not become rate of reaction.

IPC: G11B5/105
Filed: 1985-07-15
Abstract: PURPOSE:To eliminate the bleeding material to a sliding surface with a magnetic recording medium and to prevent the deterioration of a conversion characteristic by forming the joint surface of a magnetic core near the sliding surface to reinforcing plates to the surface roughness finer than the surface roughness in the region apart from the sliding surface. CONSTITUTION:The constitution in which the surface roughness of the joint surface of the magnetic core near the sliding surface 6 with the magnetic recording medium to the reinforcing plates is made finer than the surface roughness in the region apart from the sliding surface is adopted to a magnetic head of which the sliding surface 6 with the magnetic recording medium is constituted by joining and uniting the magnetic core and the reinforcing plates 3 grasping the magnetic core by an adhesive agent 4.

Title: Tape driving device
Inventor: TAKAHASHI NAOKI
IPC: G11B15/29
Filed: 1979-11-30
Abstract: PURPOSE: To reduce the thickness of a tape driving device by shortening the length of the axial direction of a capstan, thus realizing a miniature tape recorder.  
     CONSTITUTION: The height of the capstan 2 is set smaller than the conventional one and then formed so that the upper end face of the capstan is positioned at the middle part of the height in the width direction of the tape 3 which is held by the cassette half 1. The width of the pinch roller 4 is also reduced, and the upper half of the width of the roller 4 presses the tape 3 between the roller 4 and the capstan 2. Thus the tape 3 is made to travel. The lower half of the roller 4 touches directly the capstan 2 to transmit an accurate torque. A part of the upper edge side of the tape 3 is driven with no contact with the capstan 2 and the roller 4. Thus the height in the longer direction of the capstan 2 can be recuced without lowering the performance by an amount equivalent to the degree of reduction of the capstan 2. As a result, a thin and compact structure is realized for a tape recorder.

Title: Valve structure in automatic gear
Inventor: KATO HIDEJI
IPC: F16H61/00
Filed: 1986-07-01
Abstract: PURPOSE:To prevent an oil leak between ports so as to reduce the shift-shock, by forming the third recessed groove between recessed grooves, which are formed on a sleeve in the circumferential direction in such a manner that the grooves correspond to the positions of the line-pressure port and the throttle pressure port, respectively, so that the oil leaking from the space between the ports can be received once and then drained. CONSTITUTION:In the circumferential direction on the surface of a sleeve 6, a recessed groove 9 is formed at a location corresponding to the line-pressure port, and another recessed groove 10 is formed at a location corresponding to the throttled-pressure port that is subject to the pressure different from the line pressure. A recessed groove 20, which runs along the circumferential direction, is formed between these recessed grooves 9 and 10. From this recessed groove 20 is formed an axial, recessed groove 21, which runs through to the tip of the sleeve 6 without interfering the recessed groove 9. Accordingly, when the pressurized oil of the high pressure line leaks from the recessed groove 9, the leaked oil is drained into the tip of the sleeve 6 by both recessed grooves 20 and 21. Thus, the oil leak from the recessed groove 10 to the throttled- pressure port is prevented, and at the same time the shift shock can be reduced.

Filed: 1981-09-30
Abstract: PURPOSE:To obtain an accurate pattern position detector which can accurately read coordinates by cutting out a video signal obtained from a video pickup system via at least two-direction detecting windows, further projecting the signal to obtain the x- and y-cut-out pieces of a chip pattern and obtaining x-axis and y-axis coordinates from the result. CONSTITUTION:The coordinates of a point P1 is obtained at a binary video signal with detecting windows a, b. In the x-axis position, a video data in the window a is projected to scan the data in the outward chip direction and hence in the direction of an arrow 11, thereby detecting a cut-out piece A of the initial peak value. Since the distance Xa between the piece A and the point P1 is obtained, the position of the x-axis direction of the point P1 can be obtained. Then, the y-axis position of the point P can be obtained similarly to the x-axis direction. In this manner, the coordinates of the point P1 can be obtained. Cut-out pieces C, D are detected with detecting windows c, d, and the coordinates of a point P2 can be obtained with the distance between the pieces C, D and the point P2 obtained in advance.
