Abstract: PURPOSE:To easily offer sound volume control services to a subscriber as well with a popular telephone set by moving a sound volume control function to a subscriber circuit in an exchange from a subscriber terminal. CONSTITUTION:The subscriber circuit LC 2 and an in-house popular telephone set TEL 1 are connected through a two-line cable 6. The LC 2 is provided with a balancing network supervisory hybrid circuit BSH 3, a sound volume control circuit part 13 and a cordic circuit COD 5.

Title: Automatic balance net setting circuit
Inventor: SUENO MINORU
IPC: H04Q1/56
Filed: 1986-02-27
Abstract: PURPOSE:To set an optimum balance net on-line in a short time by measuring the characteristic of a hybrid circuit including the impedance of a subscriber while the balance net is switched by applying an existing tone signal to an exchange and automatically selecting an optimum balance. CONSTITUTION:The hybrid circuit 1 has four types of balance nets 2, and is connected to a cordic 4. When a subscriber hooks off, the exchange transmits a dial tone to the subscriber through a time switch 8. At that time, while a reflected signal measuring instrument 5 measures a return loss appearing in a four-line side output by reflecting in the hybrid circuit 1, a changeover switch 3 switches the balance net 2, and the return loss corresponding to each balance net 2 is stored in a return loss memory part 6. After the return losses of four types of balance nets 2 are measured, a selection circuit 7 sets an optimum return loss among the measured return losses in the return loss memory part 6, and selects the corresponding switch in the changeover switch 3, whereby an optimum balance net is set.

Title: Light wave interference measuring instrument
Inventor: YAMAURA HITOSHI
IPC: G01B9/02
Filed: 1992-02-28
Abstract: PURPOSE:To eliminate the occurrence of a measurement error caused by uncoincidence between two beams by giving a phase difference which relies on the physical properties of an object to be measured to polarized light with respect to the object before separating two linearly polarized light rays contained in one orthogonally polarized two- frequency beam of two coherent light rays to which a frequency difference is given. CONSTITUTION:Laser light emitted from an acoustooptical element 4 is separated into P-polarized light La1V and S-polarized light Lb1H through a polarization beam splitter 6. The P-polarized light La1V is introduced to a no-polarization beam splitter 8 after reflection 7 and the S-polarized light Lb1H is introduced to another no- polarization beam splitter 9. On the other hand, the laser light emitted from another acoustooptical element 5 is made incident to a polarization beam splitter 13 after passing through a wave plate 10, Farady medium 11, and another wave plate 12. Since a phase difference is given to circularly polarized light in the opposite direction when the polarized light passes through the medium 11, the P- and S-polarized light from the wave plate 12 contain a phase difference. The phase difference depends upon an electric current flowing to a coil 11a. Therefore, the phase difference can be measured by means of a phase measuring instrument 20 and the value of the electric current flowing to the coil 11a can be found by means of a CPU 21.

Abstract: PURPOSE:To encapsulate a specified quantity of mercury n a glass bulb without generating noise, crack, breakage by impregnating a porous glass body having a melting point, which is lower than the softening point of the glass bulb, with mercury, and thereby forming a mercury emitting element. CONSTITUTION:A porous glass body made from a solder glass powder having a low melting point is impregnated with a certain quantity of mercury, and thereby a mercury emitting element 17 is formed. This element 17 is heated by hot air or with a burner, etc., at a temp. below approx. 500 deg.C which is the melting point of the glass body being lower than the softening point of a glass bulb 11. This causes the element 17 to emit a certain quantity of mercury in the bulb 11, and the molten porous glass body is fusion attached to the gap between the internal circumferential wall at one end of the bulb 11 and the periphery measuring surface of a stem 12b. This allows encapsulation of the specified quantity of mercury while bulb deformation due to heating is prevented along with precluding the generation of noise, crack, and breakage due to movement of the element 17.
