Title: Fixing method of lens
Inventor: TERAI SEIJI
IPC: G02B6/32
Filed: 1985-01-10
Abstract: PURPOSE:To prevent a lens from axial shift and angular vibration, etc., to make the optical axis of the lens coincide with the axis of an insertion hole and to fix the lens precisely on a lens holder by forming a solder adhering groove into which fused solder flows on the center part of the outer peripheral wall of the lens. CONSTITUTION:The outer diameter of the outer peripheral wall 1B of the lens 1 is formed so as to be tightly adhered to the inwall under the state that the lens 1 is inserted into the insertion hole 3. Under the state that the lens 1 is set up on a prescribed position of the insertion hole 3 of the lens holder 2, an inflow hole 6 connected to the solder adhering groove 10 is formed on the shell part of the lens holder 2. When the lens 1 is inserted into the prescribed position of the insertion hole 3, the optical axis of the lens 3 coincide with the axis of the insertion hole 3 and axial shift and angular vibration are not generated. Under said state, used solder 7 is injected from respective inflow holes 10 and poured into the groove 10 and hardened to solder the lens 1 to the lens holder 2.

Title: Communication controller
Inventor: TANAKA ATSUSHI
IPC: H04M11/00
Filed: 1991-01-14
Abstract: PURPOSE:To effectively suspend a public line when no effective data is transmitted/received by providing a transmitting/receiving data storing means and storing a transmitting/receiving data until receiving a call originating instruction signal after a call is disconnected. CONSTITUTION:An address information storage circuit 8 stores party address information in the case of originating a call and after the lapse of prescribed time, a timer circuit 10 outputs a timer over signal. When it is detected that no effective data communication is executed during the period of a call holding state, a transmission/reception circuit 9 outputs a disconnection instruction signal. When the call originating instruction signal is received during the period of the call holding state after the call is temporarily disconnected, the call is set by using the party address information held in the address information storage circuit 8. The call is stored in a transmitting/receiving data buffer 7 until setting the call again by a call origination/disconnection control circuit 4 after the disconnection instruction signal is received from the circuit 9. Thus, when no effective data is transmitted/received, the call to the public line is efficiently suspended.

Abstract: PURPOSE:To obtain the uniform machining quality by obtaining an arithmetic result by a specified arithmetic expression from the positional information of X and Y axes, obtaining Z axis coordinates corresponding to the arithmetic result and controlling the Z axis by a drive part. CONSTITUTION:An NC controller 1 drives the X and Y axes at least on this laser beam machine. The positional information of the X and Y axes showing the position of a machining head 13 incorporated into the Z axis is then received from the NC controller 1 and an arithmetic part 3 obtains the arithmetic result by the specified arithmetic expression. The arithmetic result is received and the height of the Z axis inputted from an input device 7 is substituted in a transformation expression and the Z axis coordinates corresponding to the arithmetic result are obtained by a transformation part 6. The Z axis coordinates are received from the transformation part 6 and the Z axis is controlled by the drive part 10. Consequently, even if the transmission distance of the laser beam is changed, uniform machining can be always performed.

IPC: H04B3/04
Filed: 1987-01-09
Abstract: PURPOSE:To quicken a leading characteristic by providing a small signal detection means detecting a voice presence signal with a small level. CONSTITUTION:When an overflow detection means 9 discriminates whether overflow is occurred or the overflow is going to be occurred the content of accumulation is corrected so that the counting means 8 completes the accumulation of a prescribed time earlier. Moreover, a voice presence deciding means 7 and the counting means 8 accumulate only the voice presence time and allow a maximum value retrieval means 5 to obtain a maximum value at every arrival of a prescribed time, thereby preventing the malfunction of a gain control means 6 at no sound or when a pulse noise is inputted. Furthermore, a small signal detection means 10 controls it to quicken the accumulation of the counting means 8 against the voice presence signal of a small level, thereby quickening the leading characteristic. Thus, the stable gain control is applied even to an excess input signal.
