Title: Laser beam machine
Inventor: SHIRAI TAKASHI
IPC: B23K26/02
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To perform detection with excellent accuracy and high-speed machining without losing the reflection quantity of the sensor beam by adjusting the distance between the axis of a collimator lens and the axis of a machining lens so that the sensor beam passes through the focal point on the incidence side of the machining lens. SOLUTION: The sensor beam 10 is adjusted to pass the focal point F2 on the incidence side of a machining lens 53 by changing the distance δx2 between the axis C1 of a collimator lens 4 and the axis C2 of the lens 53 to be machined. Because the sensor beam 10 passes through the local point F2 , the optical passage of the sensor 10 leaving from the machining lens 53 and incident on a work 60 is parallel to the optical axis of the laser beam 50, and because the sensor beam 10 is perpendicularly incident on the surface of the work 60, the reflected sensor beam 10 can be passed on the same optical path same as the original path. The reflected sensor beam 10 can be prevented from being deviated from a sensor beam incidence part 3, and the reflection quantity of the sensor beam 10 on the surface of the work 60 can be prevented from being lost.

Title: Electronic telephone set
Inventor: OSAJIMA MASAHIRO
IPC: H04M1/26
Filed: 1986-10-31
Abstract: PURPOSE:To avoid the overflow of an undesired current by decreasing and increasing the current supplied to a dial circuit when the dial circuit has no working and has its working respectively. CONSTITUTION:When a dial circuit 1 has no working, the current of about 50 A is supplied to the terminal VD of the circuit 1 from the exchange side via the resistance 65 of high resistance value. In this case, the voltage of the terminal VD is kept at a constant level by a Zener diode 63 and a capacitor 64. When a signal is applied to the circuit 1 from a dial key, the voltage of a terminal SG is changed to a low level from a high level and a working signal is produced to show that the circuit 1 is started. When a transistor TR61 is turned on, the current supplied to the terminal VD is equal to the parallel sum of a current conducted through a resistance 66 and the TR61 and a current produced by a resistance 65. Thus a current sufficient to actuate the circuit 1 is obtained.

Title: Method for eliminating scale of plate-type heat exchanger
Inventor: ODA KAZUSHI
IPC: F28G9/00
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To quickly perform scale elimination on the entire surface of a plate with a small amount of ozone and nitrogen by allowing a liquid or a nitrogen with the decomposition operation of contamination or sterilization operation to flow in two flow directions, namely from the upper to the lower part and from the lower to the upper part of a plate gap. SOLUTION: After an elimination liquid is allowed to flow into equipment from a lower liquid pipe 5 and then is circulated from the lower to the upper part of a plate gap, it is drained toward the outside from an upper liquid pipe 4. Then, after the elimination liquid is allowed to flow into the equipment from the upper liquid pipe 4 and is circulated from the upper to the lower part of the plate gap, it is drained toward the outside from the lower liquid pipe 5. At this time, the elimination liquid collides with a scale and new ozone and nitrogen are constantly supplied on a plate wall surface that opposes the flow direction of the elimination liquid, thus eliminating contamination sufficiently and hence performing scale elimination on the entire surface of the plate quickly with a small amount of ozone and nitrogen.
