Title: High density magnetic recording media
Inventor: NAKAMATSU YOSHIROU
IPC: G11B5/72
Filed: 1978-07-19
Abstract: PURPOSE: To reduce the probability of head crash, to protect the magnetic layer even with head crash and to reduce the probability of error occurrence, by increasing the recording density through the coating of snake oil on the magnetic layer.  
     CONSTITUTION: On the Al substrate 1 of disc shape, the magnetic coating 2 is applied so that thick external circumference and thin inner circumference can be obtained, and further on it, the snake oil 3 is uniformly applied. The surface 11 of the substrate 1 has microscopically unevenness even with fine polish, and the surface 21 of the coating 2 also has unevenness. But, the surface tension and viscosity of the oil 3 makes the upper surface 31 flat even with unevenness of the lower surface 21 and lubrication action can also be obtained.

Abstract: PURPOSE:To supply a large amount of mixture from a branch path of small flow resistance when an engine is operated at a high speed with a large load, by narrowing a distance between the volute part side wall face in a volute final end part and the side wall face of a partition smaller than a branch width and forming a narrowly throttled part between these side wall faces. CONSTITUTION:The second narrowly throttled part 16a in width smaller than a width of a branch path 24 is formed between a side wall face part 15a of a valute part B and the second side wall face 14b of a partition 12, and the bottom end part of a stem guide 10 is protruded from the second bottom wall face part 22b. Accordingly, an area between the side wall face part 15a and the guide 10 is also formed to a narrowly throttled part in a width smaller than the width of the path 24. A flow speed of the second mixture flowing into from the path 24 is partly increased at flowing in through the narrowly throttled part, then this mixture diagonally collides with an upper side of the first mixture turning along a side wall face 15 of the volute part B. In consequence, a flow of the first mixture is deflected facing downward to flow into a combustion chamber 4.

Abstract: PURPOSE:To set effectively programs to a memory of a fixed capacity by controlling the capacity per program. CONSTITUTION:A CPU21 detects the ON state of a dip switch 26 and sets a special mode, and a normal copy mode is set when the switch 26 is kept off. The numerical value N is supplied by ten keys 27 in a special mode. Then the CPU21 decides another test mode is set by the switch 26 as long as the value N is set at <=50 or >=77. When the value N is set between 51 and 76, the CPU21 sets a capacity set mode. Then the CPU21 reads the data on the address to the value N out of a ROM24 to send it to a display drive circuit 29 and displays both the program number P and the step number S to a display device 30. An optimum combination of both numbers P and S is decided and an entry key 28 is pushed to set a program memory 23 in the constitution of memory displayed at the device 30.

Title: Photoreceptive member
Inventor: SAITOU KEISHI
IPC: H01L31/0248
Filed: 1984-05-02
Abstract: PURPOSE:To manufacture a photoreceptive member suitable for image formation with interferential monochromatic light under easy control by making the distribution of Ge atoms in the 1st layer ununiform in the thickness directon of the layer and by incorporatig a conductivity controlling substance into at least one of the 1st and the 2nd layers so that it is ununiformly distributed in the thickness direction of the layer. CONSTITUTION:When the interface 703 between the 1st layer 701 and the 2nd layer 702 and the free surface 704 of the 2nd layer 702 are not parallel to each other, reflected light R1 and emitted light R3 resulting from incident light I0 are different from each other in forward direction as shown in figure A, so the degree of interference is reduced as compared with a case where the interface 703 and the surface 704 are parallel to each other in figure B. Accordingly, even when interference is caused, the difference between light and darkness in the interference fringe pattern is made negligibly smaller in the case A than in the case B as shown in figure C. As a result, the quantity of incident light in a small part is made uniform.

Abstract: PURPOSE: To spread an air bag for preventing falling off at a proper timing. CONSTITUTION: A secondary collision sensing means (internal pressure sensor, touch sensor, etc.) is furnished to sense collision of a hood air bag 15 with a pedestrian 13, and the timing at which a fall-off preventive air bag 16 is spread, is determined by the elapsed time since the pedestrian 13 made secondary collision with the hood air bag 15. This nullifies the error due to dispersion of the requisite time until the pedestrian having encountered the collision makes secondary collision with the hood air bag 15, and the fall-off preventive air bag 16 can be inflated and spread at a proper timing, and it is possible for the pedestrian 13 on the hood 14 to be prevented from falling off certainly.

Title: Biaxially oriented co-extrusion laminate polyester film, manufacture thereof, and magnetic tape
Inventor: HELLMANN JOERG
IPC: B41M5/41
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To satisfy both flat surface and coarse surface in the surface of a film, improve a frictional property, and lessen the transfer characteristics of a surface form by allowing two outer layers to have each specific Ra value, Rz value, the number of projection and height of projection. SOLUTION: This is a biaxially oriented coextrusion laminate polyester film consisting of three layers of at least a base layer and two outer layers A and C. The outer layer A and C constitute the surface of a laminate polyester film by holding the base layer. The outer layer A is that the number N of projection and height (h) of projection satisfy formula 1 in Ra <=15 nm and Rz <=150 nm and 0.36 mm<2> . Also, the outer layer C has an Ra value larger than an Ra value of the outer layer A, and the number Nc of projection and (h)c satisfy formula 2 in 0.36 mm<2> . Then, a haze is 0.4%/μm or less per unit thickness at this time. When a magnetic layer is formed on a film in this fashion, it has an anti-frictional property, and can decrease the transfer of a surface form as well.
