SiCl4, SF6 and gases for a flame are then fed to a synthesizing torch 2 for a clad, fine powder of silica glass contg. F is synthesized in a flow 4 of a flame, and the powder is deposited on the side of the base material 5 to form a porous layer 6 for a clad. The base material 5 and the layer 6 are sintered by heating to 1,500-1,600 deg.C with a heating element 7 to obtain a transparent base material 8. Thus, a base material for a multimode or single-mode optical fiber having a core-clad structure can be manufactured without using any expensive dopant.

Title: Variable capacity vane pump
Inventor: HASEGAWA KAZUHIKO
IPC: F04B49/00
Filed: 1981-01-23
Abstract: PURPOSE:To save the energy consumption for driving the pump itself, by enabling the adjustment of the maximum delivery through an electric-hydraulic servo mechanism. CONSTITUTION:By the attraction of a solenoid mechanism 1, a spool 3 will move through a control rod 15 against a spring 6 then ballanced and stopped. Upon the movement of the spool 3, a port 25 will open and the oil from an oil source 16 is led to the right chamber in a cylinder 5. Since the piston 4 is fixed, the cylinder 5 is driven to be moved to the right. Consequently the port 25 will close gradually and when closed completely the cylinder 5 will stop. When the cylinder 5 moves to the right in such a manner, the flexure of the spring 8 is increased through a spacer 7 thus to increase the force for pushing a cam ring 12 to the right through the piston 9 resulting in the increase of the maximum delivery pressure of the pump.

IPC: G08B25/10
Filed: 1989-01-19
Abstract: PURPOSE:To allow one receiver to monitor radio waves transmitted from plural transmitters by generating an alarm corresponding to each inherent signal when the inherent signal is not detected for more than a prescribed time. CONSTITUTION:If a signal from the #1 transmitter 1a does not reach the receiv er 2, the signal is not inputted from a signal identifier 23 to its corresponding #1 reset circuit 24a and a #1 counter circuit 25a continuously counts up the frequency of a clock generator 26. When the counted value exceeds a set value set up by a count-up detecting circuit 27a, a signal is outputted from the circuit 27a and an alarm is outputted from an alarm device 28a. The state means the disconnection of the 1st transmitter 1a and the abnormality is detected. The disconnection other transmitters 1b to 1n can be similarly detected. Thus, radio waves transmitted from plural transmitters 1a to 1n can be monitored only by one receiver 2.

Title: Image processor
Inventor: YAMAMOTO HIROAKI
IPC: G06T1/60
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To provide an image processor in which the capacity for a line memory is reduced, the power consumption is decreased and the reduction magnification is reduced. SOLUTION: Each of line memories 6-15 has a capacity of 20% of picture element number by one line of each image. For example, in the case of 45% reduction, 4 lines are referenced as maximum to reduce the image. Since the image reduced in the line direction is received as an input image signal 1, image signals by 3 lines are stored in line memories 6-8, 9-11, 12-14 by one line each. The image by 3 lines is stored by the capacity by 2 lines. A density calculation section 5 uses only the input image signal 1 and outputs of the line memories 8, 11, 14 to calculate the density by the projection method. A line memory operation control section 17 controls the combination of the line memory in use based on a magnification 4 or the like.
