Title: Electronic equipment
Inventor: KATOU HARUHISA
IPC: G06F15/02
Filed: 1983-07-26
Abstract: PURPOSE:To prevent an unnecessary leakage of current in a backup capacitor by charging the capacitor only when a battery is replaced while the capacitor is not charged in an in-use state. CONSTITUTION:When a battery cover DK is slid as shown by an arrow A, a switch S interlocked with the cover DK moves to turn on, and the capacitor C starts being charged by the battery B. While the battery B is replaced by opening the cover K, the capacitor C is charged sufficiently, and a memory M is backed up with charges accumulated in the capacitor C at the moment the battery B is detached; when a new battery B is installed and the cover DK is closed, the switch S turns off again and the capacitor C is disconnected electrically from the battery B. Therefore, the capacitor C is connected to the battery B electrically only when the cover DK is opened, so no unnecessary leak current flows in the normal in-use state and the life of the battery is prolonged.

Title: Fm modulator
Inventor: OKADA YOSHINORI
IPC: H03C3/08
Filed: 1984-07-04
Abstract: PURPOSE:To improve the linearity of an FM modulator by connecting collector outputs of transistors (Trs) whose emitters are connected via a capacitor by way of a diode to provide the mutual relation of the change in both the collector outputs. CONSTITUTION:A current signal Ib in response to an input voltage signal 18 flows to the collector Trs 19, 20, a collector current of the Tr 20 flows to a Tr 23 through a capacitor 25 at the conducting state of the Tr 23 and the collector current of the Tr 19 flows to the Tr 23. The emitter voltage of the Tr 24 is lowered by the current Ib flowing to the capacitor 25 and the Tr 24 is conductive, then a part of the current Ib flows to a resistor 33, the base voltage of the Tr 23 is decreased rapidly and the collector current is lowered. Then a diode 27 starts conducting attended with the rapid reduction of the base voltage of the Tr 24 and the collector voltage of the Tr 23 is increased rapidly, and the operations above are repeated. Thus, a signal Ib is proportional to the change in the oscillating frequency and the linearity of the FM modulator is improved.

Title: Radar speedmeter
Inventor: TOUJIYOU NAOYUKI
IPC: G01S13/91
Filed: 1977-11-16
Abstract: PURPOSE:To avoid the mismeasurement caused by the transmission waves of other rader speedometers even when more than one unit of the speedometer are actuated simultaneously, by varying intentionally the carrier frequenct within a range which gives no effect to the speed measurement. CONSTITUTION:The oscillation frequency of Gunn oscillator 4 connected to DC bias power source 5 is modulated through saw-tooth wave generator 6 to be turned to carrier wave 7. This carrier wave 7 is then radiated toward flat car 2 through antenna 9 and via circulator 8 in the form of transmisstion wave 10. The reflected wave 11 from car 2 is received at antenna 9 and then transmitted to mixer 13 via circulator 8 in the form of reception wave 12, and then the difference frequency component of wave 7 and 12 are mixed and then detected. After this, the output is filtered through low-pass filter 14, and the frequency of obtained Doppler signal 15 is counted by counter 16 with every fixed period. Thus, the counted frequency is converted to the speed of flat car 3 to measure the shifting speed of the running car. In this way, the accurate speed measurement is ensured even though other wave sources approximate to the frequency of oscillator 4 may exist.

IPC: B29C39/38
Filed: 1982-08-06
Abstract: PURPOSE:To minimize generation and residue of voids, by a method wherein after decompressed and defoamed, synthetic resin is poured into a mold containing a material to be impregnated under a normal pressure, and the resultant is pressurized and then a process of decompression and pressurization is repeated at least once by finally maintaining pressurization. CONSTITUTION:After a synthetic resin 4 is agitated and defoamed by a mixer, it is gradually poured into the bottom of a fiber mold 2 until a material 3 to be impregnated is completely covered with. After the inside of the pressurization tank 1 is returned to a normal pressure, it is pressurized. In a conventional impregnation process, the resin is hardened by heating under pressurization thereafter to complete the process of impregnation. According to the present impregnation process, after a normal pressure pouring pressurization, a normal pressure and pressurization is again repeated once or several times and thereafter it is hardened by heating. By this processing, the inevitably generating voids can be minimized and the generated voids can be dispersed as minute voids.
