Patent JP-H08331016-A (JP)
Title: Relay amplifier
Inventor: SAKAMOTO HIROTOKU
IPC: H04B1/76
Filed: 1995-06-02
Abstract: PURPOSE: To prevent oscillation by detecting a bypass signal amount from a transmission antenna to a reception antenna. CONSTITUTION: A pilot signal FP with a frequency different from a received frequency is injected to an amplifier 2 from a pilot signal oscillation circuit 8, and a pilot signal detection circuit 11 at an input side of the amplifier 2 detects the level of a bypass signal FP' of the pilot signal. Then a phase of the detected bypass signal FP' of the pilot signal is compared with a phase of the pilot signal FP and a phase shift amount of a phase shifter 3 is controlled with a phase control signal 9 so that the phase of the bypass signal FP' is inverted to minimize a danger of oscillation. Thus, even when a signal level of a bypass signal 5 of a transmission signal 10 is increased by any causes, since the phase of the bypass signal 5 is inverted to the phase of the reception signal 6, the oscillation of the relay amplifier is not caused.

IPC: H04B10/50
Filed: 1984-07-02
Abstract: PURPOSE:To receive stably a burst light signal by amplifying the difference between outputs of a preamplifier which are passed through a delay circuit and not passed through the delay circuit. CONSTITUTION:The signal after the opto-electric conversion of a photodetecting element 1 is amplified by the preamplifier 12. The output of the preamplifier 12 is divided into two; one is inputted to the delay circuit 13 having delay time T equal to the width of a pulse with a maximum transmission speed and its output is supplied to the negative input of a differential amplifier 14. The other output of the preamplifier 12 is inputted to the positive input of the differential amplifier 14 as it is and its output is inputted to a Schmitt trigger circuit 16 through a capacitor 15. Input/output characteristics of the circuit 16 are as shown in a figure. Therefore, the input DC voltage of the circuit 16 is set to V0 almost in the middle of voltages V1 and V2 through a variable resistance 17 and a resistance 18, thereby obtaining a correct output waveform.

Title: Air conditioner
Inventor: IZEKI TAKAYUKI
IPC: F25B41/00
Filed: 1994-06-20
Abstract: PURPOSE:To return refrigerating machine oil to a compressor without retaining it in a refrigerating cycle by using HFC-single or mixed refrigerant as a refrigerant, using a refrigerating machine low in compatibility with the refrigerant and using helical pipelines as a discharge pipe and an inlet pipe directly connected to a horizontal compressor. CONSTITUTION:As the refrigerating machine oil of a horizontal compressor 2, the mineral oil with the satisfactory results of a conventional refrigerant CFC12 or HCFC 22 is used. A discharge pipe 11 outgoing from the horizontal compressor 2 is formed in a helical pipeline in order to absorb vibration and prevent the retention of the refrigerating machine oil. An inlet pipe 12 incoming to the horizontal compressor 2 is also formed in a helcal pipeline. Thus, the refrigerating machine oil is not retained in the discharge pipe and the inlet pipe, and particularly, the refrigerating machine oil is surely returned to the horizontal compressor 2 from an evaporator 3. Accordingly, not only a production system similar to a conventional one can be employed, but also the reliability of the system can be realized.

Abstract: PURPOSE:To simplify the setting of a unit price of a commodity whose unit price changes daily by clearing a unit price which is stored in a PLU memory so that a new unit price can be set, when a power source is turned on first after a date has changed. CONSTITUTION:When a power source is turned ON, a date comparing means 3 compares a date which is brought to time counting by a timepiece circuit 1 and a date which is stored in a date set memory 2. In case of discrepancy, a unit price of a commodity name to which a unit price clear flag 6 is set in a PLY memory 5 is all cleared. Subsequently, when a date of the circuit 1 is set to the memory 2, the commodity whose unit price is cleared is brought to list display on a CRT, and a unit, a unit price, etc. can be changed. In such a way, setting of a unit price of a commodity whose unit price changed daily such as perishable foods, etc. can be executed simply without being forgotten. In this regard, when the power source is turned ON for the second time and thereafter, only the commodity to which a unit price is not set is displayed.

Title: Afocal optical system
Inventor: SASAYA TOSHIHIRO
IPC: B23K26/06
Filed: 1986-06-13
Abstract: PURPOSE:To use an optical element or the like against a high intensity of light in a high-energy density beam with a high durability and a high precision by arranging the optical element between an expanding afocal optical system and a reducing afocal optical system. CONSTITUTION:A laser beam 3a emitted from a laser light into an expanding afocal optical system 1 has the luminous flux diameter expanded to become a laser beam 3b by the system 1 and has the luminous flux reduced to the same value as the beam 3a by a reducing afocal optical system 2 and is emitted as a laser beam 3c. An optical element 4 is arranged in parallel rays of the expanded beam between the optical system 1 and the optical system 2. The element 4 is relatively easily affected by the intensity of light; but since the element 4 is not inserted to the beam 3a but is inserted to the beam 3b expanded by the optical system 1, the energy density is reduced to about 1/10 because the area ratio is increased about 10 times. Since optical systems 1 and 2 are relatively freely arranged in the laser beam if only a space permits, the number of degrees of freedom of design is large.
