Title: Connecting structure of optical fiber
Inventor: KUROSAWA YUTAKA
IPC: G02B6/24
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To prevent the influence on the transmission of light signals even at the time of movement of a connection reinforcing member and to improve the reliability of transmission by ordinarily maintaining the radius of curvature of optical fibers to a specific length or above by flexible covering materials for covering the parts of the optical fibers exposed near the connection reinforcing member. SOLUTION: The reinforcing sleeve 20 is brought into tight contact with the circumference of an optical fiber fusing part 11 by thermally shrinking the sleeve after the sleeve is mounted at the outer side of the optical fiber fusing part 11, by which the sleeve is molded to a rod shape of a circular shape in section. The protective tubes 21 are formed of the materials, such as rubber, having flexibility, and are cylindrical members having a length size of about some tens mm which maintain the radius of curvature of >=30mm at all times, thereby permitting the curving of the optical fibers 10. The protective tubes 21 are formed to the shape with which their inside surfaces are mounted in tight contact with the outer peripheral surface of the optical fibers 10 as a whole.  The tubes are fixed to the reinforcing sleeve 20 by their own shrinkage force when their one-side ends 22 are put on the outer side of the reinforcing sleeve 20.

Title: Color liquid crystal display element
Inventor: UNNO AKIRA
IPC: G02F1/1335
Filed: 1995-06-13
Abstract: PURPOSE: To prevent peeling of the film on a color filter by specifying the coefft. of linear expansion of a buffer film. CONSTITUTION: When heat is given to color filters 5, buffer film 20 and lower substrate 1 in the production process of a color liquid crystal display element P1, these members thermally expands. The lower part of the color filters 5 (in contact with the buffer film 20) is stretched by the buffer film 20, while the lower part of the buffer film 20 (in contact with the lower substrate 1) is stretched by the substrate 1 so that thermal stress generates in the lower part of the filters 5 or the film 20. However, by controlling the coefft. of linear expansion (a) of the buffer film 20, the coefft. of linear expansion (b) of the substrate, and the coefft. (c) of linear expansion of the color filter to satisfy the relation of |a-b|<5×10<-6> and |a-c|<5×10<-6> , the thermal stress is rendered small.

Title: Metal joint structure and manufacturing of inner grand
Inventor: KATOU KENTAROU
IPC: F16L23/00
Filed: 1995-05-22
Abstract: PURPOSE: To provide a metal joint structure of very high sealability capable of reducing the cause of particle generation as far as possible and having its gasket reclaimable CONSTITUTION: A stable mirror finished surface sealing of wide working face is accomplished by making a ring-shaped protrusion 6, which is a sealing surface, with a high hardness clean stainless steel and the section of the ring-shaped protrusion 6 made in approximately a semicircular shape. Due to the ring-shaped protrusion 6 being made to have its fastening force work only in the perpendicular direction with respect to a gasket 7, the mirror surface is not daemigod and re-fastening is possible. Because by these various means sealing of the clean stainless steel mirror finished surface gasket 7 to the clean stainless steel mirror finished surface ring-shaped protrusion 6 is possible, not only sealability become exceptionally promoted but possibility of particle generation may also be eliminated.

The sleeves 3a, 3b fitted between the steps 4 on the outside circumference of the build-up part 2 are welded 5 at the parting planes and are strongly tightened to the body 1. The one end thereof is circumferentially welded and fixed 6 to the body 1. The repair operation of the roll is thus speeded up and simplified any many times of repair are made possible.

IPC: G05B19/05
Filed: 1995-06-14
Abstract: PURPOSE: To make execution of a user program follow in real time the change of the contact information that is shared with other programmable controllers by the communication carried out via a network. CONSTITUTION: A CPU unit 1 divides a user program into a shared contact user program and an independent contact user program and stores the former program in the memory 15b or 15c and the latter program in a memory 15a respectively. An MPU 11 usually carries out only the independent contact user program stored in the memory 15a. When the shared contact information is received via a network N, the MPU 11 interrupts the execution of the independent contact user program by interruption and carries out the shared contact user program stored in the memory 15b or 15c based on the shared contact information.

Title: Electronically controlled cooking apparatus
Inventor: MAEDA MASAHIKO
IPC: F24C7/02
Filed: 1979-11-14
Abstract: PURPOSE: To improve use of a cooking apparatus, by employing such an arrangement that cooking-operation starting time can be indicated for a short time while at a displaying means when a particular section of an input means is handled after setting of a cooking-operation finishing time, and thereby making it unnecessary for the operator to calculate the cooking-operation starting time by herself.  
     CONSTITUTION: When keys on a keyboard 2 are manipulated in a required manner for carrying out a delayed cooking, a micro-computor 1 plants input information relating to the cooking-operation finishing time and information relating to the time set in a timer at corresponding regions of a memory and displays the same at a displaying means 3. With subsequent starting operation, a required program is carried out. This program calculates the operating starting time by subtracting the content in a timer counter storing region from the content in a operation finishing time storing region and stores the content in memory. Further, the apparatus is arranged  such that, when a "start" key is pushed again after termination of cooking, the  operation started time is read out from the memory region and displayed at the displaying means 3.

Title: Microcomputer
Inventor: ISHIMARU YOSHIYUKI
IPC: G06F1/08
Filed: 1989-06-09
Abstract: PURPOSE:To perform a function test in a short time without using a clock for timepiece by using a voltage detecting circuit which detects the voltage which is higher by >=2 times than the action power voltage that is applied to an input pad. CONSTITUTION:The voltage 2Vcc twice as high as the action power voltage Vcc is applied to an input pad 4 of a timepiece clock oscillation circuit 2 of a microcomputer 1. As a result, a p-channel transistor 20 is turned on. Then the input side of a buffer inverter 22 is set at an H level and the signal, the inverse of XINSTART, serving as the output of the inverter 22 set at an L level respectively. In other words, the voltage higher by >=2 times than the voltage Vcc is applied to the pad of the circuit 2 and this voltage is detected by a voltage detecting circuit 18. Thus a control signal SSL is forcibly set at an L level in an initial state. Then a CPU 15 selects a main clock phix as a clock source of a system clock phi. As a result, a program can be executed with no time delay and a function test is performed in a short time and with no use of a timepiece clock.

Title: Liquid fuel combustion device
Inventor: ISHIKAWA KATSUHIKO
IPC: F23D11/34
Filed: 1991-06-20
Abstract: PURPOSE:To provide a small-sized liquid fuel combustion device capable of starting spontaneously at low noise and expanding the control range of combustion and eliminating the deposition of tar. CONSTITUTION:A contact surface between a tip 23 23 of a vibrator 22 and a valve 25 is opened and closed by the vibration of the tip 23 of the vibrator 22. Equalized and fine particles are generated by the formation of a thin liquid film and shearing force to the liquid film while there is installed an atomizing section 20 which has a wide control range of atomization in an air supply passage 29 to a combustion section 30, thereby constituting a fuel combustion device. The air to be supplied to the air supply passage 29 is mixed with uniform and fine particles. The particulate liquid fuel is transferred to the combustion section 30 and turned into premixed air as well. Since it is turned in a flammable mixed air at the combustion section 30, there is available spontaneous ignition combustion, which reduces the length of flames. Furthermore, since uniform and fine particles are directly burned, low noise combustion is attained where there is no tar deposited, which makes it possible to prevent combustion failure or generation of odor as well.
