Title: Diversity combined reception system
Inventor: NAKAMURA SHIZUHITO
IPC: H04B7/08
Filed: 1995-06-19
Abstract: PURPOSE: To effectively prevent the state of inverse-in-phase combination and to improve the reliability of a receiver. CONSTITUTION: An individual signal detection part individually detects respective signal levels Va and Vb of two input signals IFM and IFS, and a synthesizing signal detection part detects a signal level Vc of a signal synthesizing two inputs. When two input signals are in-phase, a signal level (Va+Vb) simply adding their signal levels Va and Vb is equal with the signal level Vc of the synthesized signal. When those input signals are deviated from the in-phase, however, the synthesized signal receives inter-signal interference and as a result, the relation of (Va+Vb)>Vc is provided. The difference has tendency to be reduced when the phase difference between two input signals is small, to be increased when the phase difference is increased, and to be made maximum when the phases are inverted.  Then, an inverse in-phase discriminating part compares the sum signal (Va+Vb) of detected signals with the detected signal Vc and when difference |(Va+Vb)-Vc| is larger than a prescribed value, it is discriminated that two input signals are in the relation of inverse-in-phase.

Title: Method for manufacturing laminated board for chemical plating
Inventor: YASUKUI MITSUNORI
IPC: B32B7/06
Filed: 1985-07-11
Abstract: PURPOSE:To achieve uniform and smooth adhesion and to enable release without generating rupture or cracks, by using a plastic film, of which the m.p. and steam permeability respectively have specific values or more, as a release sheet. CONSTITUTION:In preparing a release sheet, an adhesive layer is formed to a plastic film of which the m.p. is 200 deg.C or more and the steam permeability is 5g/m<2>.24hr.atm.25mum or more. As the plastic film to be used, polyethylene terephthalate or polycarbonate having an especially high m.p. is pref. from the aspect of heat resistance and usually has a thickness of 20-100mum. By this method, the steam generated from a curable resin impregnated base material can be diffused and evaporated to the outer surface of the base material and, at the same time, damage due to thermal deterioration is reduced because of high m.p. and integral molding can be performed in such a state that appearance is uniformly and smoothly held. Even at the time of release, no rupture or crack is generated.

Filed: 1991-06-24
Abstract: PURPOSE:To prevent an inverse transistor operation and to prevent an excessive current from flowing to an input side by connecting diodes respectively between a resistor/base connected to the emitter of a PNP transistor and a control circuit. CONSTITUTION:This circuit is composed of a PNP transistor Tr, control circuit C to control the base current of the transistor Tr by feeding an output voltage back, resistor RB and two diodes D1 and D2 integrally formed on a substrate forming the control circuit C. Namely, the other terminal of the resistor RB connected to the emitter of the transistor Tr is connected to the anode of the first diode D1, and the cathode of this diode D1 is connected to the base side of the control circuit C. On the other hand, the second diode D2. is connected forward between the base of the PNP transistor Tr and the control circuit C. Therefore, since a base current IB does not flow even in the case of VIN>VO, the PNP transistor Tr does not generate the inverse transistor operation and no excessive current flows.

Title: Manufacture of permanent magnet
Inventor: YAMAGAMI TOSHIAKI
IPC: C22C38/00
Filed: 1988-06-20
Abstract: PURPOSE:To obtain a permanent magnet of high performance by using the material of specific carbon concentration on the permanent magnet which makes base constituents of a rare earth element, a transition metal element and a group IIIb element. CONSTITUTION:A rare earth element (however, at least a kind containing yttrium), a transition metal element (however, a kind including one from the group IIb) and a group IIIb metal element are made base constituents. Impurity carbon acts on an R-rich phase which is a non-magnetic phase in the active rare earth element and an R-TM-B system magnet. The R-rich phase covers a magnetic phase which is a main phase, it is supposed that it is participated in a coercive force generating mechanism and magnetic performance deteriorates from the view point in which the R-rich phase acts on it. Since by calcination the upper limit of the impurity carbon is carbon concentration 1000ppm in a permanent magnet and this rate is left in the magnet in the form of carbon, it is desirable that it is 0-1000ppm as long as a decarbonating process is inserted.

Title: Power failure detecting circuit
Inventor: YAMAMOTO TETSUYA
IPC: G01R19/165
Filed: 1987-06-19
Abstract: PURPOSE:To raise the reliability for detecting a power failure at the time when an AC power supply voltage has dropped, to improve the power failure detection response time, and also, to reduce the variance, by providing a hysteresis characteristic to a comparator of an input level monitoring circuit part. CONSTITUTION:When a voltage of an AC power source 1 drops, the output of a rectifying element 2 does not exceed a high level of a comparator 3a, and the output of the comparator 3a is held in an H state as long as a voltage drop state continues. As a result, in a timer circuit part 4, as time elapses, a time-up operation is executed, the value of a power source abnormality detecting output PF is varied to L from H, and a power supply voltage drop signal is outputted to an external circuit. In such a case, a hysteresis is supplied to the comparator 3a, therefore, when the AC power supply voltage is normal, a period in which a value of a rectifying output voltage is lower than a value of a detection reference voltage is shortened. In such a way, a variation due to the phase of power failure of the time until a power failure signal is sent out can be suppressed.
