Filed: 1993-12-07
Abstract: PURPOSE:To easily identify a coming call by storing a call sound to be generated corresponding to the telephone number in a call sound storage means and producing a call sound corresponding to the telephone number of the telephone call. CONSTITUTION:A facsimile 10 stores the signal pattern of the telephone number to be used as a telephone communication in an EEPROM 32 in advance. A call message is stored in an audio DRAM 34 corresponding to the telephone number. Thus, when a telephone call comes by the telephone number, the corresponding call message is read out of the audio DRAM 34 and is generated from a speaker 26. Accordingly, when one facsimile 10 is used by many people, to whom the telephone call comes can be easily identified compared with the conventional way of identifying the call sound which rings in synchronism with the signal pattern of the call signal.

Title: One frequency simplex communication system radio equipment
Inventor: MANZEN YOSHIHISA
IPC: H04B15/06
Filed: 1994-12-12
Abstract: PURPOSE: To make it possible to turn on the power source of a voltage control transmitter at all times by the use of a simple constitution, to eliminate the stabilization waiting time of the transmitter at the time of the input of the power source and to quickly stabilize communication by suppressing the sneak path of the output of the voltage control transmitter to a reception circuit. CONSTITUTION: By providing a transmission-reception changeover circuit 7 on the terminal of an antenna 1 and cutting off the antenna to a transmission side and a reception side at the time of transmission and reception, the output of the voltage control transmitter 4 on the transmission side is prevented from leaking to the reception side via the antenna. The phase of the output signal of the voltage control transmitter 4 is inverted by 180 degrees by a phase inversion amplifier 8, is radiated from a printing wiring and is made to cancel with spatial radiation leakage. Thus, by adding a simple circuit, the leakage between transmission and reception is suppressed, the turning on the power source of the voltage control oscillator on the transmission side becomes possible and stable transmission and reception become possible without waiting oscillation stabilizing time.

Patent JP-H03168395-A (JP)
Title: Blower
Inventor: SUZUKI SOUZOU
IPC: F04D29/44
Filed: 1989-11-28
Abstract: PURPOSE:To prevent a flow separation, reduce a noise due to a turbulent flow during air-blasting, and reduce the size of a blower by constituting the curvature of an inlet-side tip-part of an orifice in such a manner that it becomes minimum at the middle of a longer edge side of a front panel having a nearly rectangular form and maximum at the middle of a shorter edge side. CONSTITUTION:When an axial-flow impeller 7 rotates, the flowed-in air is discharged out of a blower room 2 via an orifice 9. At this time, since a front panel 4 is of a rectangular form, a distance between the axial-flow impeller 7 and a side wall 5b is large at a section on the longer edge side, and therefore a centripetal, inflow air current G is generated. However, since curvature R2 at an inlet side tip part 9a is set in such a manner that it becomes the smallest in comparison with other parts, the flow G smoothly flows along the curved line without taking place a separation of the air current due to sharp bending. In addition, on the smaller edge side, a distance between the axial-flow impeller 7 and a side wall 5a is small, and an inflow air current H mainly consists of the air in the axial direction. Therefore, by setting curvature R1 at the inlet side tip part 9a at the maximum in comparison with other parts, the dimension of the blower room 2 in the shorter edge direction can be reduced.
