Title: Semiconductor integrated circuit
Inventor: ASAKAWA TATSUJI
IPC: H01L29/78
Filed: 1977-10-03
Abstract: PURPOSE: To make it possible to form a resistor on an integrated circuit without increasing the number of processes for the formation.  
     CONSTITUTION: As for a MISFET integrated circuit, parts which can be used as a resistor are separation layers 14 in addition to P--type well 2. Shallow P-type layer 14 is formed by implanting B ions and at the same time, resistor layer 15 is also formed. Layer 15 is connected to metal electrode 13 via P + -type layer 16. In this way, the amount of implanted ions is controlled within the range until the achievement of separation so as to increase specific resistance and since the depth can be made below 1μ, the sheet resistance can be increased. In addition, since depth (x j ) is not deep, width (w j ) hard to be reduced becomes nearly equal to (w) because of ion-implantation, the control can be nearly attanined as the mask is, and the integration density improves through fining, so that the resistance value will be uniformed

Title: Electrodeless field discharge excimer lamp and electrodeless field discharge excimer lamp device
Inventor: MATSUMOTO MINORU
IPC: H01J65/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To increase luminous efficiency, to efficiently feed electric power to a discharge space and to make a uniform and stable electric discharge by providing a trigger electrode and an inner electrode with two slit sections in the whole length direction of the tube axis in a tube with a high electric insulation property, applying a high frequency in a specific range, and making a field electric discharge. SOLUTION: When the angles θ1, θ2 of two slit sections are set to 90 deg., the most right/left symmetrical electric discharge is attained. The position of plasma in a discharge container 1 can be controlled by changing the angles θ1, θ2. When the lighting frequency of a lamp is high (radio frequency of 1-100 MHz), the probability that excited rare gas atoms meet other atoms is increased even if the discharge gas pressure is low. The discharge container 1 is sufficiently cooled than the center section of the lamp, the discharge gas is also cooled, and the luminous efficiency of ultraviolet rays is further improved. Since the discharge gas pressure of the lamp is low, the discharge start voltage becomes low, and the starting property of the lamp is improved.

Title: Method of specifying fault occurring section in line switching network
Inventor: FUJITA MASAKATSU
IPC: H04L12/26
Filed: 1990-05-08
Abstract: PURPOSE:To specify the fault section of a switching line network inexpensively and surely in a short time by monitoring data between points of the line switching network and comparing the data with a central processing unit. CONSTITUTION:A CPU 15 compares a transmission data detected by a monitoring device 14a connected to the point A of a line between a terminal equipment 11a and an LC line concentrator 12a with a reception data detected by a monitoring device 14e connected to the point E of a line between a terminal equipment 11b and an LC line concentrator 12b. When both data are different from each other, it is detected that a line network between points A, E has a fault. Then the CPU 15 narrows the detection section of a line network between the points A and E as a comparison data between points A, C, data between points C, D, data between points D, E respectively. If the data between the points D and E are different from each other, it is specified that a section between the points D and E has a fault. Thus, the fault section of the switching line network is located inexpensively and surely in a short time.

Abstract: PURPOSE:To proceed the service on the occurrence of a fault by providing 1st and 2nd optical switch means to the system, outputting a signal selected by the 2nd optical switch means to a relevant optical transmission line and outputting a signal from a prescribed optical transmission line to the optical transmission line of the 2nd optical switch. CONSTITUTION:An optical signal from an active optical transmission section 300 is sent to, e.g. a 3rd optical transmission line via a 1st optical switch means 110, a 2nd optical switch means 130 and an optical split section 150. An active optical reception section 300 of other equipment awaits an optical signal sent from the 3rd optical transmission line and a control section recognizes that the 3rd optical transmission line is interrupted because no signal is received and sends an alarm to one transmitter. The one transmitter receives the alarm and selects the means 130 to use 2nd and 4th optical transmission lines for the transmission reception of the optical signal. Since the 4th optical transmission line is normal, the optical communication service is continued.

Abstract: PROBLEM TO BE SOLVED: To attain effectiveness and economy of a welding operation for a deep position that has reach by fixedly attaching a joining tool to an ultrasonic horn with a screw member capable of advancing and retreating vertically to the vibrating direction. SOLUTION: This resonator is so constituted that a joining tool 2, which a length integer times as long as the half wave length of the resonance frequency, is fixedly attached to an ultrasonic horn 1 with a screw member 3 capable of advancing and retreating vertically to the vibrating direction X, thereby vibrating the tip end face 2b of the joining tool 2 in the same direction as the vibration of the ultrasonic horn 1, and enabling welding to be performed properly by ultrasonic vibration. In the case where the joining tool 2 can no longer be used through the repeated repair by grinding its tip end face 2b, the ultrasonic horn 1 can be used again, in which tuning of a resonant state is properly maintained, by merely exchanging the old joining tool 2 with a new one, with the ultrasonic horn 1 attached to the device.

Title: Molding of optical element
Inventor: KAWAMURA EIJI
IPC: C03B23/00
Filed: 1991-04-22
Abstract: PURPOSE:To prevent a raw material glass from fusion bonding to the molding surface of a mold. CONSTITUTION:At least, the molding surface of both the mold units is cooled immediately before supplying a raw material glass soften or molten by heating to a pair of mold units. The raw material glass is subsequently supplied between the mold units and then pressed by the molding surface of the mold units to mold the objective optical element. Since the temperature difference between the molding surface and the raw material glass is large due to cooling of the molding surface, fusion bonding between the molding surface and the raw material glass can be prevented in this pressing.

Title: Liquid crystal display device of guest-host system
Inventor: TSUTSUI TAKASHI
IPC: G09F9/46
Filed: 1981-07-30
Abstract: PURPOSE:To obtain sufficient contrast without using any polarizing plate by using flexible  polymer films which are optically anisotropic as electrode substrates, laminating >=2 layers of  liquid crystal cells and orienting liquid crystal materials in orthogonally intersecting directions  while no electric fields are applied. CONSTITUTION:When an electric field is applied to a titled device and rays A, B from above  pass through an upper electrode substrate 5 consisting of a polymer film, the rays are separated in the two orthogonally intersecting optical axis directions of the polymer films. When the  separated rays pass through a liquid crystal material 10 and enter a middle electrode substrate  6, the rays are separated to the two orthogonally intersecting optical axis directions. Further,  the rays pass through a liqud crystal material 10', enter a lower electrode substrate 7, and are  again separated in the two orthogonally intersecting optical axis directions. Even when the ray B entering the parts where no electric fields are applied is separated to the light in the two  orthogonally intersecting oscillation directions, the materials 10, 10' are homogeneously oriented in the orthogonal directions and therefore the rays receive dye absorption strongly and are colored. The ray A entering the parts where the electric field is applied, the materials 10, 10'  orient homeotropically and since the multichromatic dyes change the arrangements of dye  molecules, the ray is hardly absorbed, and appears white - transparent.
