Patent JP-H0285801-A (JP)
Title: Optical fiber for temperature sensor
Inventor: TSUCHIYA SHINICHI
IPC: G02B6/02
Filed: 1988-09-22
Abstract: PURPOSE:To obtain the optical fiber which is compact and has excellent stability by alternately forming glass layers which are largely varied in the coefft. of thermal expansion and forming a core into a coaxial multilayered structure. CONSTITUTION:The core 5 having the refractive index higher than the refractive index of a clad 4 of the optical fiber is formed to the inner side of the clad 4. The core 5 is made into the multilayered structure alternately formed with the glass layers 8 having the large coefft. of thermal expansion and the glass layer 7 having the small coefft. of thermal expansion in >=10 layers to a coaxial cylindrical shape. The dopant concn. of the respective glass layers 7, 8 of the core is so determined that the dopant concn. of the low thermal expansion dopant layer 9 and the high thermal dopant layer 10 is higher nearer the central part of the core. The refractive index distribution thereof is also so determined that the increase rate of the refractive index distribution 6 is higher nearer the central part and the coefft. of the refractive index distribution is <=1. Scattered light is continuously generated along the longitudinal direction with respect to incident light and the backward scattered light is generated as the incident side propagation component thereof. Since the coefficients of the thermal expansion of the glass layers 7, 8 have the coaxial cylindrical distribution varying alternately large and small, a strain is generated with a temp. change in the boundary between the glass layers 7, 8 and a change in the optical constant such as Rayleigh scattering constant is easily caused by this strain.

Title: Upper bending device
Inventor: HONGO TOSHIO
IPC: B21D19/08
Filed: 1985-10-25
Abstract: PURPOSE:To eliminate the need for succeeding work which straightens a springback after working and to improve the efficiency by making the work sheet being overbent at the prescribed angle on the inclined face of the progressing lower die front face in case of the work sheet being upper-bent by the sinking of a cushion pad. CONSTITUTION:A work sheet 7 is placed on a cushion pad 3 and lower die 6 and abutted to an abutting piece 10. With the descent of a beam 11 by operating a ram 12 in succession, the lower face of a bending die 13 comes into contact with the work sheet 7 on the cushion pad 3 and the pad 3 is sunk with pinching the sheet 7 between the bending die 13 and cushion pad 3. In this case, the lower die 6 is advanced with the work face of the backup member 15 which descends integrally with the bending piece 13 being engaged with the rear face 17 of the lower die 6 and the edge part of the sheet 7 is bent in the same angle with both inclined faces 8, 14. The sheet 7 overbent >=90 deg. in this way is shaped automatically in the bend angle of 90 deg. by the springback after being removed from the device.

Title: Clamp device
Inventor: KAWASHIMA NOBUYOSHI
IPC: B23Q3/06
Filed: 1983-12-19
Abstract: PURPOSE:To make plural motions attainable in a speedy manner as well as to aim at simplification in engagement or disengagement, by connecting an intermediate part of a clamping plate, whose one end is rotatably attached to a table via a long hole, and a piston rod of a cylinder attached to the table with a link. CONSTITUTION:When a piston 2a is made to go up in an A direction, a clamping plate 6 first goes up as far as a portion for a long hole 4c, while a pin 5 turns round in circular form as shown in a B mark in a state of shifting to an upper end of the long gole 4c. That si, a vertical lifting movement is turned into a circular turning movement. Next, when the piston 2a is further made to go up as in a C mark, the pin 5 moves to a lower part of the long hole 4c and thereby the clamping plate 6 turns round in a large circular form of an arrow D. Therefore, an upper part of a work W and the clamping plate 6 are largely separated away. In this connection, clamping takes place in doing the reverse motion against this. Thus, not only clamping or releasing for the work on a table or a jig is speedily performable but also an automatic engagement or disengagement device is adoptable as the clamping plate largely separates from the work so that operation efficiency is well improvable.

Abstract: PURPOSE:To increase the processing speed of a microprogram and to simplify a microprogram controller by switching architecture modes via a controller and using an exclusive microprogram for each architecture. CONSTITUTION:The address of a microinstruction sequence to be executed is set to a register 1 and an executing architecture mode is decided and set to a register 2. A single entry of an address array 4 corresponding to the contents of the register 1 is read out to a signal line 12. A comparator 4 compares the architecture mode under execution that is held by the register 2 with bits 0-2 of the register 1 respectively. If coincidence is secured among these comparison results, the output of a buffer memory 3 is validated and the next address is set to the register 1. While the output of the memory 3 is invalidated and at the same time a load control circuit 6 is started via a signal line 13 when noncoincidence is obtained from said comparison. Then an address of a large-capacity memory 7 is produced by the circuit 6 and the processing speed of a microprogram is increased.

Abstract: PURPOSE:To provide the title instrument intended to measure in high accuracy the divergence of a raw material flow channel etc., so designed that an ultrasonic transmitter/receiver, etc., is (are) set up on a slice roof or apron, and the transmission distance is operated through the signals of reflected echoes due to high-frequency impulse and those from a transmitter. CONSTITUTION:An ultrasonic transmitter/receiver 10 set up on the upper surface of a slice roof 2 near the lip tip converts the electric impulse from a transmitter 13 periodically generating high-frequency impulse into ultrasonic impulse, which is allowed to make an incidence obliquely to the slice roof 2. The ultrasonic wave put into a raw material and reflected on the upper surface of an apron 3 is converted to a voltage through the transmitter/receiver 10 and amplified by a receiver 14, and the traveling time is measured and operated by an operator 15. Thence, another operator 16 makes such an operation that the transmission distance in the roof 2 is deducted from that obtained by multiplying the traveling time by the transmission velocity adjusted through the raw material temperature determined by a temperature measuring instrument 11, and the divergence of a raw material flow channel thus obtained is displayed.
