Title: Telephone exchange
Inventor: UKAI HITOSHI
IPC: H04M3/42
Filed: 1986-06-12
Abstract: PURPOSE:To discriminate a call signal for talking and a call signal for data communication in a subscriber terminal equipment side by adding a second call signal sending means to a telephone exchange. CONSTITUTION:A call signal sending circuit IRS 6 generates and sends an AC signal made by superposing a second frequency different from a first frequency on the first frequency as a call signal. A telephone set TEL 9 ansers both of call signals IRA, IRB. However, a data communication terminal DTE 10 is made to anser automatically only to the second frequency of the call signal IRB. In a TRM 8, the bell of TEL 9 is sound by the call signal IRA, and when an answer is given, communication can be made between a caller and the TEL 9. Simultaneously with ringing of the bell of the TEL 9 by the first frequency component, the DTE 10 answers automatically to the second frequency component, and the IRS 6 stops the sending of IRB, and communication data from the caller comes in automatically to the DTE 10.

Abstract: PURPOSE: To set an optional breakdown voltage for a Zener diode of an integrated circuit, by producing a plurality of semiconductor regions on a semiconductor substrate by diffusion so that the regions are partly overlapped with one another.  
     CONSTITUTION: When a P-type semiconductor is used, an N-type semiconductor epitaxial layer 12 is provided on a P-type semiconductor substrate 11 or the like. Diffusion is then performed through the surface of the layer 12 to produce a P-type region 14. A P +  region 13 is provided on the P-type region 14. A plurality of n-type regions 15, 15' are produced in the semiconductor region 14 by diffusion so that the regions 15, 15' are at least partly overlapped with each other. Lead electrodes 16, 17 are provided. Because the impurity concentration of the overlapped part of the regions 15, 15' is raised, a breakdown phenomenon takes place on a point of contact with the ordinary P +  region. Then, the pattern of a diffusion mask is altered to change the overlapped part of the regions 15, 15' to alter the impurity concentration of the part. The breakdown voltage can thus be optionally set.

IPC: F28D15/02
Filed: 1980-10-02
Abstract: PURPOSE: To facilitate the supplementary firing of a bathoboiler by a method wherein heat pipes at employed in the heating of a bath and a shower.  
     CONSTITUTION: The heat through the heat pipes 7 is transmitted from a heat exchanger 8 to heat exchangers 3 and 4 with the transmission efficiency of about 95% and more. The water temperature within a bathtub 2 is rendered to be optimum by the on-off controlling of the combustion of a burner 12 through the measurement of the temperature of a liquid 10 with a thermistor 11. At the shower part, a shower water with the same water temperature as that within the bathtub can be obtined by passing the water through the heat exchanger 4 from the shower. In this case, even if the temperature of the liquid 10 is raised by means of the thermistor 11, the temperature of the shower does not rise abruptly because the certain part of the heat from the heat exchanger 8 is absorbed to a bathing water 2. In order to raise the temperature of the shower water, it is necessary that a clock is provided at the buathtub side from the branch point of the heat pipes to prevent the heat from the exchanger 8 from flowing in the heat exchanger 3 and then set the thermistor 11 at the desired temperature.

Abstract: PROBLEM TO BE SOLVED: To prevent adding vibration to the driving system of a first actuator in an optical head by conducting a second tracking servo while moving a recording medium in a track corss direction with a tracking control signal. SOLUTION: The output of a phase compensator 26 is fed to a VCM driving circuit 34 through a phase compensator 31, a switch SW2 and a phase compensator 33. The circuit 34 drives an X direction sliding means 200 so as to move a carriage 400 in a track orthogonal direction for a tracking servo and an objective lens is always positioned at the center. Since a head section 100 is not fixed in the X direction, no vibration is added to the section 100 and an AT actuator even though the carriage 400 being placed is moved by an optical card 1 and a high precision tracking servo and a double tracking servo are conducted. Since the card 1 is moved in a track orthogonal direction, the inertial force of the means 200 does not affect an objective lens driving system and no inertial force compensating circuit is required.
