Title: Injection device in vertical type die casting machine
Inventor: NISHIURA TAKESHI
IPC: B22D17/32
Filed: 1983-05-19
Abstract: PURPOSE:To provide a titled device which yields surely and easily an injected product having good quality by the constitution in which a molten steel is injected at a high speed until the molten metal arrives at a cavity to suppress the temp. drop of the molten metal and is thereafter injected at a low speed to prevent the disturbance on the molten metal surface. CONSTITUTION:The ram 16 of an injection machine in a vertical type die casting machine is driven to rise a block 6 together with a plunger 7 and a plunger chip 5 so that the tip of an injection sleeve 4 is fitted to a stationary die 2. This state is detected with a position detector 24 and solenoid operated selector valves 19, 20 are operated to supply pressure oil from a hydraulic supply source 25 through oil flow regulating valves 21, 22 to an injection cylinder 8. The molten metal 10 on the chip 5 is injected at a high speed until just before said molten metal arrives at a cavity 3. Said position is detected by a position detector 25 which in turn actuates the valve 20 to close the valve 22 so that the molten metal is filled by a low speed injection into the cavity 3. The disturbance on the molten metal surface is thus prevented.

Title: Optical disk device
Inventor: HONJO MASAHIRO
IPC: G11B27/10
Filed: 1991-04-18
Abstract: PURPOSE:To improve the function by searching an address at the time of reproduction by writing in advance information of the field or frame number, an address, etc., processed by encoding in a field or a frame. CONSTITUTION:In an inside peripheral area 2 of an optical disk 1, the field or frame number or the sector number, an address, etc., subjected to encoding in a field or a frame are written in advance. An optical disk device reads out the inside peripheral area 2 first, reads out information of the above address etc., and stone them in the device. At the time of executing the reproduction at a high speed, an undesirable influence caused by encoding between the field or the frame is prevented by reproducing only the encoded frame of the inside peripheral area 2 first. Also, at the time of executing a random access, as well, the reproduction is started from the field or the frame of encoding in the field or the frame first. In such a can, it is also allowable that the display itself is muted to a random address, and the display is executed therefrom.

Title: Covering method of cathode with hot cathode material
Inventor: SUMI KOICHIRO
IPC: H01J9/04
Filed: 1992-04-08
Abstract: PURPOSE:To prevent a hot cathode material powder from scattering and control the coating amount and improve the properties of a cathode by charging a hole of a metal ribbon with the hot cathode material powder by a squeegee and coating the surface of a base metal of a cathode structure body with the powder punched by a press-rod. CONSTITUTION:A metal ribbon 11 is set in a powder charging stand 17 and a set quantity of a hot cathode material powder 12 is poured to the ribbon 11 from a powder pool 18. Due to the movement of the ribbon toward A direction, a hole 10 is charged with the powder 12 by a squeegee 13, depending on the thickness of the ribbon. Meanwhile, cathode sleeves having a base metal 16 at the end part are set on a cathode sleeve supporting stand 20 in a prescribed distance and the hole 10 of the ribbon and the metal 16 are made to agree each other, depending on the movement of the supporting stand 20 toward B direction and the movement of the ribbon 11 toward A direction. The charged powder 12a is punched from the ribbon 11 by lowering a press rod 14 and the surface of the metal 16 is covered with the powder. Consequently, the cathode material powder is prevented from scattering and the coating amount is controlled and thus cathodes with good properties are obtained.

SOLUTION: This image forming device is provided with the photoreceptor drum 6, an electrification device 7, an exposure device 8, a transfer device 9 and a magnetic field forming device 41. By the forming device 41, a magnetic field for promoting the rotating movement of magnetic toner is formed at the outside surface of the drum 6 between the transfer device 9 and the electrification device 7 and on an opposite side to the developing device 8. It is preferable that a magnetic drum freely rotatably supported by a shaft being in parallel with the shaft of the drum 6 is used as the forming device 41 and fitted near the inside surface of the drum 6 so as to alternately make reverse polarity appear at the surface of the magnetic drum in the rotating direction.  Besides, the image forming device is provided with a toner loosening member 42 at a position where it is opposed to the forming device 41 so as to be used together with the forming device 41 and brought into contact with the outside surface of the drum 6. When the loosening member 42 is vibrated, the attaching force of the toner is more easily weakened.

Title: Vapor cleaning device with solvent vapor producing part
Inventor: SATO AKIRA
IPC: B05D3/10
Filed: 1990-04-04
Abstract: PURPOSE: To prevent suspended matters from inhibiting generation of vapor by allowing an apparatus to have a combined structure of a vapor-washing vessel and an over-flow vessel, connecting both vessels through an opening in a nearly tetragonal shape and by making the suspended matters flow down to the overflow vessel with a gushing surface stream gushed from gushing holes of cylindrical pipes installed in the vapor- washing vessel. CONSTITUTION: Solvent vapor generated by a heater (4) at a solvent vapor-generating section (5) forms an air interface (3) by an action of a cooling coil (2) to make a space for washing various plastic products, etc., in a vapor-washing vessel (6). The filth removed by the washing falls together with a flow of the condensed solvent and floats on the solvent surface (10). A surface lamina flow from gushing holes (14) of cylinder pipes (13) makes the filth overflow to an overflow vessel (7) through an opening section (8). The solvent (15) accumulated in the overflow vessel (7) is sucked out by a pump (11) from the bottom of the overflow vessel (7) and circulated through a filter (12) and a flow rate control valve (16) to form the gushing surface lamina flow from the gushing holes (14) of the cylinder pipes (13) which are positioned at the liquid surface of the washing vessel (6).
