Title: Liquid developing device
Inventor: KARIYA YOSHINOBU
IPC: G03G15/10
Filed: 1988-07-21
Abstract: PURPOSE:To reproduce uniform black solid being free from a printing omission in a black solid area by constituting the developing device of a sleeve for carrying a liquid toner to a developing area, and a film for controlling a liquid level of the liquid toner in the developing area and having a through-hole. CONSTITUTION:The title developing device is provided with a sleeve 2 for carrying a liquid toner 3 to a developing area, and a thin film 1 having a through-hole 4 in which the diameter of a hole 4a of the opposite side to an electrostatic latent image is smaller than the diameter of a hole 4b of the opposite side to the sleeve 2 in the developing area and for controlling a liquid level of the liquid toner 3. When the sleeve 2 rotates, the liquid toner 3 is carried to the developing area, and receives pressure in a gap between the film 1 and the surface of the sleeve 2. By this pressure, on the surface of the film 1, the toner 3 projects only in the through-hole 4a, and irregularities determined by an arrangement of the through-hole 4 are formed. In such a way, by forming the through-hole 4 on the surface of the film 1 so that an irregularities distribution on the surface of the toner layer becomes roughly constant in advance, a uniform solid black development is executed.

Title: Secondary battery
Inventor: TAKAKUBO MASAAKI
IPC: H01M10/39
Filed: 1986-08-04
Abstract: PURPOSE:To make it possible to use water as the solvent of an electrolyte by using a pyrrole polymer film, in which the complex anion of transition metal soluble in water as electrolyte is electrochemically doped, in an anode. CONSTITUTION:As the active material of an anode 13, a pyrrole polymer film, in which the complex anion of transition metal soluble in water as electrolyte is electrochemically and reversibly doped, is used.

Title: Disc carrying device
Inventor: IKEDO YUUJI
IPC: G11B17/04
Filed: 1982-10-19
Abstract: PURPOSE:To attain suitable carrying of a disc, even if the inserting direction is shifted with a simple constitution, by changing the carrying direction with the differential shift in response to the difference between turning amounts of a guide member brought into contact with a disc side face. CONSTITUTION:If the disc 28 is loaded with a shift at a right angle in the carrying diretion, a difference of turning amounts is generated between guide plates 4, 5 brought into contact with the side face of the disc 28 freely turnably and a differential mechanism formed by racks 8, 9 and a pinion 14 responds the difference of turning amunts. Further, the pinion 14 is moved in response to the difference of turning amounts, and the turning direction of a roll 24 driving the disc is changed via a turning stand 19. Thus, the disc is carried suitably to the playing position of the turntable 3 to the disc loaded with the inserting direction, even if the inserting direction is shifted with a simple constitution.

Title: Magnetic head supporting device
Inventor: YOSHIDA TORU
IPC: G11B17/34
Filed: 1990-07-11
Abstract: PURPOSE:To stably write and/or read a signal by always optimizing the negative pressure state in a first recessed part which supports a magnetic head of a magnetic head supporting body. CONSTITUTION:Since a first groove 9 connecting a first recessed part 5 and a second recessed part 6 is provided above a first annular projection 3 at a upstream side in the disk rotating direction, air in the first recessed part 5 flows out from the first groove 9 to the second recessed part 6to make the negative pressure state in the first recessed part 5. Therefore, a disk is sucked to the magnetic head supporting device side by this negative pressure and is brought into contact with the magnetic head. At this time, the head pressing force with which the magnetic head presses the disk is dependent upon the repulsion of the disk and this negative pressure but is considerably dependent upon the negative pressure. Consequently, the head pressing force is always kept constant regardless of the change of rigidity of the disk.

Title: Mold for continuously casting metal
Inventor: KOYAMA KUNIO
IPC: B22D11/04
Filed: 1987-07-24
Abstract: PURPOSE:To prevent damage of a ceramic caused by thermal shock crack by joining a material having high heat resistance at outside of the ceramic so as to apply uniform compressed stress from circular direction of the ceramic in a mold lining the ceramic. CONSTITUTION:The ceramic material 2 lined in the water cooled copper mold 1 is inserted to molten metal 6 at one end thereof and the outer surface at the other end thereof is brought into contact with a copper plate 10 and cooled and at the time of starting casting, the ceramic material 2 is rapidly heated by flow of the molten metal and damage by the thermal shock. In order to prevent the above damage, the outside material 3 having high heat resistance is joined on the outer circumference of the ceramic material 2 by shrinkage fitting or casting. By this method, as the compressed stress is beforehand applied to the ceramic material 2, and expansion caused by heating is reduced and development of the crack can be reduced. Further, even if crack is developed, the crack does not open to outside, and breakout, etc., caused by holding with penetrated solidification of molten metal is not developed. Further, as the good thermal conductivity between the joined surfaces is obtd. by this joining, thickness of the ceramic material 2 can be made thicker or the temp. can be made lower corresponding to the improving quantity, and the crack can be reduced.

Title: Ink jet recorder
Inventor: HASEGAWA SHIGEYOSHI
IPC: B41J2/045
Filed: 1988-07-22
Abstract: PURPOSE:To enable a plug to be fitted and detached at a single stroke by disposing an ink-side air vent and a head-side air vent coaxially, and providing a two-layer plug. CONSTITUTION:An air vent plug 1 is constituted of a two-layer plug comprising an inner ring 101 and an outer ring 102. A supplying pipe 12 is connected to feed air from an ink-side air vent 2 to an ink container 13, and from a head-side air vent 3 to an ink jet head 10. The plug has a double-wall construction, and provides a hermetic seal by fastening air vent terminals on both the head side and the ink side. When the plug 1 is pulled outward after an air-supplying unit 16 is stopped, the outer ring 102 is disengaged from the head-side air vent terminal 3, whereby internal air is discharged. With the plug 1 pulled further outward, the inner ring 101 is disengaged from the ink-side air vent terminal 2, whereby air in the ink container is discharged. The double-wall construction ensures that the inner ring and a mating part are always first brought into contact, so that the inner ring can be always disengaged later than other plug parts at the time of opening terminals ports.

Title: System for restricting incoming call
Inventor: ITO KIYOTSUGU
IPC: G10L15/00
Filed: 1985-08-21
Abstract: PURPOSE:To allow a caller to discriminate incoming permission or restriction even through the same connection path by using voice recognition to apply incoming restriction. CONSTITUTION:A voice recognition device 6 compared a voice data of a password with a voice data of password registered in advance read from a storage device 5 to discriminate whether or not they are coincident. The voice recognition device 6 uses a general device for an unspecified caller and discrimination is attained by the characteristic of the voice of the caller even for the same password. When the connection permission is discriminated by the voice recognition device 6, a central controller 10 closes a link (c) to connect a trunk line trunk 11 to a host computer 7 via a line circuit 9 and a MODEM 8. When the voice recognition device 6 discriminates the connection restriction or the disabled recognition of the password, the central controller 10 closes a link (a) so as to allow the caller to inquire about the manager.
