Title: Multicolor image forming device
Inventor: HIRONO TATSUO
IPC: G03G15/01
Filed: 1995-04-27
Abstract: PURPOSE: To prevent the color mixture in a developing means, and to surely prevent the color mixture of a visualized image, by preliminarily providing a means bringing the developing means for every color into a non-developing state at the time capable of image forming. CONSTITUTION: An latent image for every color image formed on a photoreceptor is developed by exposure by exposing means. This device is provided with several developing device for every color arranged in parallel to the photoreceptor, and a control part 49 as development switching means capable of switching the developing device for each color to the developable state and the non-developing state.

Title: Jacking device for resting vehicle
Inventor: YAMAZAKI KAZUO
IPC: B66C23/78
Filed: 1990-04-19
Abstract: PURPOSE:To contain a jack compactly by hanging the jack from a bottom of a vehicle through turning a cylinder by means of a turning lever which operates associated with extending motion of the jack, when the jack contained in a parallel state with a bottom surface of the vehicle is extended. CONSTITUTION:In order to operate a jack which is in a contained state, a piston rod 11 which is in a contracted state is extended, and a foot plate 12 is exposed. In this case, a sliding member 23 arranged on an outer periphery of the piston rod 11 becomes free from an enforcing force due to the foot plate 12 in the contracting direction. Then, a turning lever 16 connected with the sliding member 23 by means of a main driving rod 22 becomes rotatable about a fixed axis 17. Consequently, a cylinder 10 is turned about a main axis 14 in the direction of gravity, and is hung from the bottom surface of the vehicle. In this hanging state, the turning lever 16 and a driven rod 26, which connect the fixed axis 17 and a supporting axis 27, extend most widely about a driven axis 25. Thus, a vehicle 15 is held stably by contact of the foot plate 12 to the ground surface 13.

Title: Thin film element and manufacture thereof
Inventor: ISHIHARA SHINICHIROU
IPC: H01L21/205
Filed: 1982-06-16
Abstract: PURPOSE:To prevent the yield of an element from decreasing by accumulating an amorphous Si or the like of P-I-N conductive type which contains hydrogen or halogen element on conductive substrate and then reducing the contents as compared with that after the accumulation. CONSTITUTION:An amorphous Si layer 3 which contains hydrogen or halogen element is accumulated on a conductive substrate 1, heat treated at the substrate temperature or lower at the accumulating time in an atmosphere which does not remarkably modify the surface of the layer 3 to reduce the content of the hydrogen or halogen. The higher the temperature and the treating period increase, the more the reducing amount increases. After treated at 200 deg.C for approx. 90min, a protecting film 10 of polyimide or the like for mounting aluminum electrodes 6, substrate electrodes 7, lead wirings 8, 9 is covered. When the layer 3 is thus heat treated, the mutual movement in the boundary between the aluminum electrode and the amorphous Si can be suppressed at the heat treating time of hardening the film 10, and the mutual movement based on disturbance due to heat or the like can be suppressed even out of the hardening time. Accordingly, a thin film element of high reliability can be obtained.

Title: Ink tank
Inventor: ENUMA KOICHI
IPC: B43K5/02
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To supply abundant ink to an ink discharge mechanism by arranging an expansion film and a holder for the expansion film as a movable wall part in an ink tank having the movable wall part which contains ink under a free state in hermetically sealed space, and varies its volume following consumption of the ink. SOLUTION: An ink tank cartridge for an ink jet printer contains pigment ink 4 in a container body 1, and an expansion film 5 and high viscous fluid 6 are arranged in an interfacial part of the ink 4. Further, a cover body 8 is fixed to an opening part 7 of the container body 7, and the cover body 8 is fitted as a protective component for the expansion film 5, which is equipped with an air hole communicating with the outside. When a volume of the ink 4 in the ink tank is decreased, the high viscous fluid 6 moves in a direction for an ink discharge hole 2. Further, the expansion film 5 is extended by being pulled by movement of the high viscous fluid 6 to follow the high viscous fluid 6. Thereby, a position wherein the ink 4 moves by its consumed content can be held.

Title: Semiconductor laser device
Inventor: MIYAUCHI NOBUYUKI
IPC: H01S5/00
Filed: 1989-04-24
Abstract: PURPOSE:To enable it to operate with high output by forming a stripe-shaped mesa part, wherein the width of laminate structure is made small in the region excluding the region near one end face, and a buried layer, and making the width of the laminate structure larger than the mesa part in the region near the end face. CONSTITUTION:A real refraction factor wave guide mechanism is formed by a stripe-shaped mesa part 45, wherein the width of laminate structure is made small in the region excluding the region near the end face, and a buried layer 43, and in the region near the end face, the width of the laminate structure is made larger than the mesa part 45. That is, inside a resonator, it has the real refraction factor wave guide mechanism, but in the end face region it does not have the refraction factor wave guide mechanism. Hereby, the light confining effect is weakened in the vicinity of the end face, and light density at the end face is lowered, and generation of optical damage is prevented, whereby it can be operated with high output.

Title: Optical fiber core clad with layer of low linear expansion coefficient
Inventor: YAMAMOTO FUMIO
IPC: C03C25/10
Filed: 1984-05-25
Abstract: PURPOSE:To obtain an optical fiber core capable of cladding with high speed and having superior transmission efficiency causing only small loss and high reliability for a long range of the length and being produced with inexpensive cost by cladding secondarily a thermoplastic resin exhibiting crystallinity in the molten state on the external periphery of an optical fiber strand consisting of an optical fiber and a primary clad layer. CONSTITUTION:Any liquid crystal polymer may be used for the thermoplastic resin of the secondary cladding material so far as it has <=1X10<-5>/ deg.C coefft. of linear expansion under the cladding condition. Specific examples are a thermotropic liquid crystal consisting of polyethylene terepthalate (PET) and p-oxybenzoic acid (POB). From the view point of easiness in handling the optical fiber core and alpha and the behavior of contraction at high temp, the preferred range of the POB content in the PET/POB copolymer is 40-80mol%. If such copolymer is used, a slow cooling stage is unnecessary but the cooling may be performed by quenching for a short time. Thus, high speed cladding has become realized.
