IPC: G02B6/00
Filed: 1989-04-24
Abstract: PURPOSE:To obtain the nonlinear optical fiber which is large in a nonlinear optical effect and has the element size of a practicable size by sealing a liquid or solid material dispersed with an org. material having an optical nonlinear refractive index effect into a hollow small-diameter tube essentially consisting of quartz glass, thereby forming a core part. CONSTITUTION:This fiber is formed by sealing the liquid or solid material dispersed with the org. material having the large nonlinear refractive index effect into a clad 12 consisting of the quartz glass thereby forming the core part 11. The refractive index is controlled by adjusting the dispersion concn. or the compsn. of a dispersing element, by which light is efficiently confined into the core part 11 and the large nonlinear optical effect is exhibited. The org. material having the nonlinear refractive index is selected from molecular crystalline materials or ionic crystalline materials having >=5X10<-3> esu guadratic molecular sensitivity beta or >=5X10<-36> esu cubic optical nonlinear molecular sensitivity gamma or the like in addition to a styrene deriv. (DEANST) consisting of 4-(N, N-diethylamino)-beta-nitrostyrene.

Filed: 1989-04-24
Abstract: PURPOSE:To prevent short circuit between a negative active material and a positive electrode by using an expanded grid in a negative electrode and installing projections which are in contact with the surface of the negative electrode in the inner wall of a container. CONSTITUTION:Both sides of a negative electrode 1 are pressed down with projections 5 installed in the inner wall of a container 4. The expansion of an active material of the negative electrode 1 using an expanded grid attendant on charge-discharge cycles are suppressed to avoid short circuit between a negative active material and a positive electrode 3. By coating both end surfaces of the negative plate with sulfonic acid-resistant resin, similar effect can be obtained.

Title: Arithmetic processing unit
Inventor: HASEBE ATSUSHI
IPC: G06T5/20
Filed: 1986-05-07
Abstract: PURPOSE:To store a necessary part of a partial sequence by rewriting and reduce the amount of data which is written newly, and to improve the throughput by shifting successively and rewriting data written in a work memory. CONSTITUTION:The data written in the work memory 1 is read out and latched by a register 7 while processed by a logical arithmetic part (ALU) 5, and when next data is read out after the processing, data in a register 7 is rewritten in the address of the work memory 1 out of which the data is read through a selector 8. Consequently, the data is shifted and rewritten and the system of the register 7 and work memory 1 is separated from the ALU 5 at this time, so this rewriting operation is performed simultaneously with the arithmetic processing, thereby improving the throughput.

Title: Low permittivity insulating method applicable to vlsi
Inventor: CHIN CHIEN CHIYOO
IPC: H01L21/768
Filed: 1995-04-27
Abstract: PURPOSE: To provide a method for producing a semiconductor device with reduced capacitance between adjacent conductors on a connecting layer. CONSTITUTION: A bridge is formed between the highest parts of conductors 12 at small intervals by directional growth forming a dielectric layer 14 by deciding a direction at an acute angle with respect to the plane of a semiconductor substrate 10 to form at least one gaseous dielectric layer 18. As this process is self aligning forming, the shadowing effect of the conductor itself is used of masking the growth of a dielectric material between the conductors and only very small intervals between the conductors are bridged. Continually, an inter-layer dielectric 20 is grown to complete a structure. A directional deposition method can be the electron beam evaporation of a material such as SiO2 , Si3 N4 , polyimide or amorphous Teflon.

Title: Power reduction device of multi-stage reciprocating compressor
Inventor: SAEKI SHIYOUICHI
IPC: F04B49/00
Filed: 1981-07-06
Abstract: PURPOSE:To reduce power loss to a great extent in unload operation and prevent lubricating oil from being carbonized by releasing high pressure gas at the intermediate stage into a low pressure area in said operation for reducing the pressure at the intermediate stage. CONSTITUTION:When unloaders 1h, 2h are actuated for unload operation of a compressor, a release valve 11 is simultaneously operated, thereby releasing high pressure gas at the intermediate stage into atmosphere to reduce the pressure up to an atmospheric value. Since the density of gas which comes into or out of a secondary compressor 2 is reduced, a resistance against the gas, applied while passing therethrough may be lessened, thereby reducing power loss to a considerably great extent. In addition, since increase in temperature of the gas at the intermediate stage is restrained due to the lowered passing resistance attributed to a low pressure at the intermediate stage, thereby preventing the lubricating oil from being carbonized by being exposed to the hot gas.

Abstract: PROBLEM TO BE SOLVED: To enable a stable recording or transmitting operation without interrupting the operation by forming a signal for compensating an image signal disabled in recording because of error generation while using a stored image signal, and recording this compensated image signal when an image signal recording error occurs during recording into a medium. SOLUTION: When the recording error occurs while image data for 600 sectors are recorded, similarly to the time of starting the interrupted recording or image data to an HDD 8, compensation at the time of recording error is performed for the unit of horizontal data amount in the prescribed area of memory 6 and a data amount for the least common multiple of recording unit of HDD 8. Namely, on the assumption that the recording error occurs when the 361st sector in the image data for 600 sectors is recorded on the HDD 8, a recording address corresponding to the preceding 360th sector is set to the HDD 8 and a reading address is set to a memory controller 7 so that the compensation in case of recording error can be performed.

Title: Manufacture of semiconductor device
Inventor: OKA HIDEAKI
IPC: H01L21/20
Filed: 1988-04-27
Abstract: PURPOSE:To form a semiconductor element selectively in a crystallized region by executing crystal growth of an amorphous material layer by making use of a seed region of polycrystalline silicon as a seed. CONSTITUTION:Pattern of island-shaped regions 104 of amorphous silicon and coupling regions 105 of amorphous silicon are formed; an impurity 106 at about 10<18>-10<22>/cm<2> is included in one part of amorphous material layers constituting the coupling regions and the island-shaped regions. Crystal growth is started from a seed region 301 as a starting point; since a crystal growth speed in a region 304 doped with the impurity is fast as compared with an undoped region, the region 304 is crystallized fast. As a result, the crystal growth progresses from the region doped with the impurity as the starting point; a crystal is grown nearly in an identical plane direction; it is possible to reduce the occurrence of a defect, a stress or the like that is caused by a difference in the crystal growth speed between crystal growth planes. By this setup, a semiconductor element can be formed selectively in a crystallized region.

Abstract: PURPOSE:To permit a callee to recognize a caller by displaying information showing the caller on the storage means of a telephone set on a caller-side in a display means on a telephone set on a callee-side. CONSTITUTION:When a dial means 7 is operated, a system is connected to the opposite telephone set, and data of the telephone set on a transmission-side, which is stored in a data storage part 2, is transmitted from a transmission part 3 through a control part 1. When there is a communication request to the control part 1 through a reception part 4 on the other hand, a line is artificially emptied, and it comes to a standby state until data (personal code number and the like) which has previously been stored in a data storage part 2 or data which has gone through a normal process are received. When data are received, data are displayed in a display part 5 through the control part 1, and ringing tone is generated. The callee decides whether to receive data or not by viewing the displayed personal code number of transmission-side data. For not receiving data, the line can be disconnected by the operation of the dial means 7.
