Abstract: PURPOSE:To apply a large SSB power to antenna with less power loss by using an amplifier of the conventional class C operation as a power amplifier to be modulated so as to apply amplification of a single side band (SSB) system signal with excellent power efficiency. CONSTITUTION:A voice input signal AF is modulated at a balanced modulator 7 by a local oscillation frequency fS3, only one SSB wave is obtained via a BPF8, a pulse width modulation wave is obtained from a signal F obtained by envelope detection of the SSB wave at a detector D and from a triangle wave from a triangle wave generator 10 at a comparator 9, the modulated wave is amplified by a pulse amplifier 11 and subject to power amplification at a switching power amplifier 12. An LPF13 eliminates the switching frequency and its harmonics and the output is subject to amplitude modulation by the class C operation radio frequency power amplifier 17. A phase modulator 14 uses the AF input to apply phase modulation to a local oscillation frequency fS4, its output PM is converted into a prescribed SSB radio frequency using a local oscillation frequency fS5 at a frequency converter 15, an amplifier 17 is excited by using a signal amplifying the radio frequency at an amplifier 16 to obtain a radio frequency SSB power subject to amplitude modulation.

Title: Semipermeable membrane
Inventor: IKEDA KENICHI
IPC: B01D71/68
Filed: 1990-08-29
Abstract: PURPOSE:To prevent delamination by embedding a fabric in a sponge-like layer and making the thicknesses of respective sponge-like layer parts almost equal and providing skin layers to both surfaces of the sponge-like layer. CONSTITUTION:A sponge-like layer 1 is constituted of an intermediate part 10 in which a fabric 2 is embedded and sponge-like layer parts 11, 12. Dense skin layers 31, 32 are formed to both surfaces of the sponge-like layer 1 and the thicknesses of the sponge-like layer parts 11, 12 on both sides of the fabric 2 are made almost equal and the ratio thereof is usually set to about 0.8-1.2. Even when pressure acts on a semipermeable membrane from either one of both surfaces thereof, the skin layers 31, 32 receive said pressure and this pressure is supported in a tensile stress state only by the fabric 2. No tensile stress is generated in the skin layers 31, 32 and the sponge-like layer parts 11, 12 and all of them become a compressed state. By this method, the delamination of the fabric and the sponge layer parts is prevented.

IPC: H04B3/54
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To use a distribution line and a telephone line, etc., in a broadcasting and communication, etc. SOLUTION: The antenna terminal of a transmitter is connected to one single line of the distribution line and the telephone line, etc., with a capacitor which is intrinsically synchronized with a transmission frequency and a grounded terminal is grounded. But an electric power frequency in the case of the distribution line and the transmission call and reception call frequency in the case of the telephone line are adopted as the ones being different from the transmission frequency of the transmitter. The antenna terminal of a receiver is connected to the single line such as the distribution line and the telephone line, etc., where the transmitter is provided in the above method with the capacitor which is intrinsically synchronized with the transmission frequency and the grounded terminal is grounded.  But, when a variable capacitor is used so as to enable receiving multiple stations, the electric power frequency and the transmission call and reception call frequency are not synchronized with the variable capacitor.

Title: Oscillation system for highly stable reference frequency
Inventor: SUZUKI SHINJIRO
IPC: H03L7/107
Filed: 1986-09-25
Abstract: PURPOSE:To transmit a signal of highly stable and highly accurate frequency by providing a variable loop filter of the output of a phase comparing circuit, obtaining phase synchronism by a phase comparing circuit, and then adding band limitation to the variable loop filter and controlling a highly stable voltage- controlled oscillator. CONSTITUTION:The phase of a signal obtained through the 1/176 frequency dividion of a highly stable 10 MHz oscillator 9 is compared by a phase compar ing circuit 7 with the phase of a signal obtained by divding the frequency of the 3.58 MHz voltagecontrolled oscillator 5 by 63 and the loop filter 8 synchronizes the 3.58 MHz voltage-controlled oscillator 5 with the highly stable 10 MHz oscillator 10. The 3.58 MHz oscillator 5 is held highly stably. A phase comparing circuit 2 compares the phase of the output of the highly stabilized 3.58 MHz oscillator 5 with a color burst signal outputted by an extracting circuit 1. A lock detecting circuit 3 monitors the phase comparing circuit 2 and lowers the cutoff frequency of the variable loop filter 4 on detecting the acquisition of synchronism, thereby controlling the highly stable 10 MHz voltage- controlled oscillator 10 slowly.

Title: Scavenging and exhaust equipment for diesel engine
Inventor: TAKAHASHI MOTOYUKI
IPC: F02B33/44
Filed: 1984-10-31
Abstract: PURPOSE:To effectively take out the exhaust recovery energy in a supercharger as the output of a crankshaft by alternately applying both the intake pressure from the supercharger and the scavenging pressure, which is lower than the intake pressure, to the inside of the lower cylinder by means of an opening or closing control of a scavenging and intake valves. CONSTITUTION:The supercharged air from a supercharger 9 is introduced first from an inlet pipe 17 into an inlet chamber 13. When the piston 4 goes up in a compression stroke, the intake pressure, which has been introduced into the inlet chamber 13, close a scavenging valve 14 and opens an inlet valve 15, thereby operating as the pressure in the lower cylinder of the piston 4. On the other hand, when the piston goes down in the expansion stroke, said pressure pens the scavenging valve 14 and closes the inlet valve 15, thereby lowering the pressure in the lower side of the piston 4 down to the normal scavenging pressure. Owing to these two operations, the exhaust recovery energy from the supercharger 9 can be utilized as the output of a crankshaft 7. At this time, an adjusting valve 18 is adjusted as necessary so that the most effective scavenging and exhaust operation suitable for the supercharging efficiency at that time can be obtained.
