Abstract: PURPOSE:To receive a telephone call coming from an external line even at a power fault when the power source of a base unit is interrupted and data for talking such as an identification code is destroyed and the telephone call comes from the external line to ring a bell of a telephone set. CONSTITUTION:When power is not interrupted, an output is obtained at a power circuit 271, and then a relay 232 is driven, then a hybrid circuit 230 is connected to a line 23 through a normally opened contact NO of a relay 232, then the cordless telephone set is used. When power is interrupted, no output is obtained at the power circuit 271, the base unit 2 is not actuated and since the relay 232 is not driven in this case, the telephone set 4 is connected to a line 3 through a normally closed contact NC of the relay 232. Thus, the telephone set 4 is operated normally during power failure, the telephone set 4 receives a telephone call coming from the external line and makes a call to the external line.

Title: Spread spectrum communication equipment
Inventor: ISHIGAKI YUKINOBU
IPC: H04J13/00

Abstract: PURPOSE:To prevent the reduction in the stability of a receiver side especially by comparing the phase of an output signal of a frequency division means with the phase of an output signal of a 1st multiplier means at a phase comparator means so as to apply feedback to a 2nd multiplier means. CONSTITUTION:The period of a pseudo noise code outputted from a pseudo noise code generator 3 is a multiple of a natural number of the period of a reset pulse signal (d) or its reciprocal. Moreover, the phase of the output signal of a frequency divider 22 is compared with the phase of an output signal (c) of a multiplier 15 at a phase comparator 19 to match the oscillating frequency of a VCO 21 with a frequency f2 accurately. That is, a phase locked loop is formed by the phase comparator 19, an LPF 20, the VCO 21 and the frequency divider 22 to apply negative feedback to the VCO 21. Thus, the stability of clock is much improved and the stability at the reception side is not reduced especially.

Abstract: PURPOSE:To prevent the surface of a lens from being corroded by ozone and to eliminate deterioration in picture quality by providing a member which adsorbs or decomposes the ozone in the vicinity of the incidence end surface and/or projection end surface of a SELFOC lens to reduce the concentration of the ozone near the SELFOC lens. CONSTITUTION:The member 16 which adsorbs the ozone is fitted nearby the projection end surface of the SELFOC lens 13. This member 16 is formed by scattering particulates of activated carbon on one side of a both-sided tape. Ozone produced by the charge corotron of an optical printer is adsorbed by particulates of activated carbon sticking on the both-sided tape nearby the SELFOC lens 13 and the ozone concentration decreases. Consequently, the surface of the SELFOC lens is hardly corroded and a print image of good quality is obtained even in long-period operation.

Title: Magnetic head and recording and reproducing device using the same
Inventor: KANAI HITOSHI
IPC: G11B5/00
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To obtain a wide dynamic range without changing the bias point from the optimum position by using a magnetic field generating means which generates a magnetic field to compensate an antimagnetic field applied from a direction fixing magnetic layer to a direction rotating magnetic layer. SOLUTION: When a sensing current J is applied, the layer 22a is magnetized by the magnetic field generated by the current J because a spin bulb element 24 is maintained offset near the magnetic shield layer 22a, and a leaked magnetic field is used to return magnetization Mp in a free magnetic layer 34 to the track width direction. Namely, magnetization Mp in a pin magnetic layer 32 is downward along the z-axis so that magnetization Mf in the layer 34 is influenced to rotate upward along the z-axis. By applying the current J from the front side, magnetization Ms upward along the z-axis is generated in the layer 22a and the leaked magnetic field gives an effect to the layer 34 downward along the z-axis. Thereby, magnetization Mf in the layer 34 compensates the antimagnetic field from the layer 32 and the leaked magnetic field from the layer 22a. Thus, magnetization is maintained along the track width direction.
