Title: Led array
Inventor: ISAMOTO KEIJI
IPC: F21V8/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To efficiently utilize the light by directing a reflecting face of a reflecting means to a light outgoing face side of a LED, so that the outgoing light from the corresponding LED can be directly applied to the same. SOLUTION: A reflector 7 mounted on an LED chip 1 comprises an almost triangular section, and a reflecting face 7a directly to the LED chip 1 is slanted by 45 degree. The reflector 7 is mounted so that the outgoing light from the adjacent LED chip 1 is directly applied to the same. The reflecting face 7a is a mirror face, and totally reflects the incident light. Whereby the light 9c laterally emitted from the LED chip 1 is totally reflected by the reflector 7, and can be emitted from the LED array only by one reflection by making the incident angle to the mirror face 2a less than a critical angle. That is, most of light is emitted from the LED array 10 directly or through one reflection, so that the LED array 10 can efficiently utilize the light.

Title: Sheet transport device, image reader and image forming apparatus provided with one of the devices
Inventor: SUGITA SOJI
IPC: B65H5/36
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To keep a transport guide from being charged with static electricity by providing a sheet guide means with an anti-static electricity agent formed by a mixture of a surfactant and a resin. SOLUTION: A transport guide 49 is adapted to introduce the leading edge of a document P passed through a paper feeding and separating part 35 into a nip of a pair of transport rollers 42, 43, and introduce the leading edge of the document passed through the paired transport rollers 42, 43 into a nip of a reading sensor 44 and a white document pressing plate 45. An anti-static mold material (anti-static material) is used for the transport guide 49. This is obtained by mixing resin in a surfactant such as a material obtained by alloying hydrophilic polymer in resin such as ABS(acrylnitryl-butadiene-styrene ternary copolymer), PC(polycarbonate)+ABS, and these are liable to form a leakage path for electric charges, so that electric charges generated by sliding of a document are instantaneously discharged in the air.  As a result, static electricity is hardly accumulated in the transport guide 49.

Title: Manufacture of metal magnetic powder
Inventor: HIRAI SHIGEO
IPC: B22F1/02
Filed: 1986-03-20
Abstract: PURPOSE:To obtain the needle-shaped or square-shaped metal magnetic powder having good coersive force by heating the suspension of powder mainly consisting of oxyironhydroxide or iron oxide up to the temperature higher than the predetermined temperature under the existence of nickel salt and urea causing the nickel compound to be adhered to the surface thereof and reducing such powder through the heating under the gas phase. CONSTITUTION:The nickel salt and urea form stable composite salt in the water. This composite salt is decomposed by the hydrolysis when it is heated up to 80 deg.C or higher and the nickel compound is adhered to the surface of particles of powder suspension mainly consisting of oxyironhydroxide or iron oxide. The metal magnetic powder obtained by heating and reducing the raw material powder adhering such nickel compound under the gas phase conforming to the ordinary method has a low coersive force even in case amount of nickel is small. Therefore, according to this method, the metal magnetic powder consisting of square type needle-shaped particles having a high axial ratio can be obtained easily with the coersive force as small as about 1,000Oe.

Title: Speed change hydraulic circuit
Inventor: TSUKAMOTO YUUJI
IPC: F15B11/00
Filed: 1981-04-30
Abstract: PURPOSE:To prevent the stick slip caused by an accumulator during the low speed, by providing a switch interlocked with a cam in the deceleration interval thereby functioning an electromagnetic valve in front of the accumulator. CONSTITUTION:When operating an exchange valve to move a cylinder rod 9 to the right, an accumulator 8 will function in the high speed motion interval thus to prevent the water hammer. While when operating the exchange valve 2 to move the rod 9 to the left, the cam 5' will also move to the left thus to function a reduction valve 3 and move the rod 9 with low speed. Here a switch 6 is functioned by the cam 5' to function an electromagnetic valve 7 and to turn off the accumulator 8, thereby such phenomena as the smooth motion will not be performed can be prevented because the accumulator 8 is existing in the pressurizing circuit side. During the low speed, the kinetic energy is low thereby the influence of the water hammer is low.
