Title: Intermittent receiver
Inventor: INOUE MASAYUKI
IPC: H04B1/16
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption due to the power off of a D/A converter for frequency control while not receiving and to receive an incoming control channel by performing the frequency control of a voltage controlled crystal oscillator and the timing correction of a TDMA timer before receiving the incoming control channel. SOLUTION: A CPU 7 stores a frequency control value at that time in memory 8, turns off the power source of a D/A converter 5 for frequency control and makes it in a non receiving sleeve state in a waiting state maintaining TDMA timing synchronization with a base station. Together with it, the frequency control value stored in the memory 8 is reset after turning on the converter 5 before receiving an incoming control channel. A correction value of TDMA timing is calculated from the frequency control value and sleeve time, power consumption in a waiting state can be reduced by correcting the timing to a TDMA 6 and also, the incoming control channel can be received.

Title: Phase shifter
Inventor: TOYONAGA NORIYASU
IPC: H04B7/02
Filed: 1983-09-29
Abstract: PURPOSE:To obtain easily a phase shifter with high adjusting band for phase matching by dividing an original signal into two via a branching device, forming an n-multiple harmonic signal and an (n-1)-multiple harmonic signal, and extracting a difference signal by means of a filter from the result of multiplication of two signals at a multiplier. CONSTITUTION:When an original signal sin omegat is inputted respectively to a loop A comprising components 12, 13, 14 and a loop B comprising components 15, 16 by an oscillator 10 via the branching device 11, a high frequency group is formed through a phase shifter unit 12 of the loop A, and a signal sin n(omegat-phi) is selected from the group at the band-pass filter 14. On the other hand, a high frequency group is also formed at a nonlinear circuit of the loop B and a signal sin (n-1)omegat is selected by the band-pass filter 16 from the group. An output signal sin (omegat-nphi+lambda/2) is obtained by multiplying both the signals at a multiplier 17 and selecting the result at a band-pass filter 18. This results in that the phase shift of nphi-lambda/2 is obtained while the phase shift by phi is set by a phase shifter unit.

Title: Lubrication device for bearings of vertical pump
Inventor: OOTANI KENJI
IPC: F04D29/06
Filed: 1981-11-13
Abstract: PURPOSE:To shorten the time of dry operation of a vertical pump, which uses the water to be pumped up as a lubricant for bearings, by supplying the water immediately at the starting time of the pump. CONSTITUTION:When pump is started, part of the water to be pumped up is immediately supplied to the bearing 9 through a lubricant supply pipe 10, so that the time of dry operation is shortened to a large extent. When the pump is at a standstill, the function of a check valve 11 brings about the condition that the lubricating water is stored in the lubricant supply pipe 10, so that supply of the water to the bearing 9 is made immediately when pump operation is resumed. Accordingly, the time of dry operation is suppressed to almost nothing even though the pump is frequently started and stopped to contribute to prevention of a hot damage of bearing 9.

Title: Ink supply mechanism for printing machine
Inventor: KOJIMA YASUTAKA
IPC: B41F31/15
Filed: 1983-09-29
Abstract: PURPOSE:To enable even supply of ink onto a plate surface by rotating a form roller successively connected to one or more vibrating rollers in the opposite direction to an ink fountain roller while a plate cylinder rotating in the opposite direction is connected successively thereto. CONSTITUTION:An ink fountatin roller 1 always rotates in a fixed firection to attach ink N in an ink fountain 9 and shifts it onto the surface of form roller 2 turning in the opposite direction. The ink N attached to the form roller 2 is distributed evenly with vibrating rollers 3, 4 and 6 and further fed onto the plate surface 8 on a plate cylinder 7 successively connected thereto and turning in the opposite direction. Here, the vibrating rollers 3 and 4 work to level the fixed amount of ink N always fed and attached to the form roller 2 while the vibrating roller 6 works to level the ink N distributed again to remove uneven inking partially caused after it is fed onto the plate surface 8 to print. This can prevent printing of an uneven density to ensure the finishing of printing with a high quality.

Title: Growth accelerator for cultured laver
Inventor: CHIKURA TATSUMI
IPC: C05B7/00
Filed: 1989-07-12
Abstract: PURPOSE:To obtain a growth accelerator for cultured laver, as the damage of the cultivated laver by disease-causative microorganisms and other sea weeds is prevented, by admixing phosphate salt, nitrate salt, organic acid and saccharides to a solution mainly composed of sulfur-containing amino acids. CONSTITUTION:The subject laver growth accelerator is obtained by addling, as nutrients for cultivated laver, phosphate salt, nitrate salt, organic acid and saccharide to a solution mainly composed of sulfur-containing amino acids. The nets for laver cultivation are dipped in the solution and used in the cultivation whereby the sulfur-containing amino acids are directly absorbed into the laver cells to grow and strengthen them. Simultaneously the nutrients of nitrate salt and phosphate salt are given to the laver to accelerate the growth. The organic acid makes the solution of the sulfur containing amino acids weakly acidic to prevent green laver from sticking to the nets. Further, the organic acid can kill the microorganism causative of red rotting in the cultivated laver, and control other sea weeds whereby the growth of laver is helped and the quality is improved.

Title: Wave force fin propelling device
Inventor: NOBUNAGA HIROSHI
IPC: B63B39/06
Filed: 1985-08-21
Abstract: PURPOSE:To enable energy saving operation, by a method wherein a fin for thrust is varied in conformity to a water flow varied by waves flowing along the side of a ship hull, and energy of waves is recovered to convert it into propulsive energy. CONSTITUTION:During sailing of a ship, waves flow along the outer board of a ship hull. In this case, a water level, a flow rate, and a period of water are measured by a water level and current meter 9, and inclination (the direction of a flow) of waves in a fin 2 for thrust is measured by water gauges 10 and 11. Based on the information, a signal is fed from a computer 12 to a solenoid 13. The solenoid 13 controls operation of a solenoid valve 14, and controls an amount of working oil to a servo motor 6. This controls the angle of eleva tion of the fin 2 for thrust to a value optimum to the direction of a flow and the velocity of flow of sea water. Thus, when an angle of elevation is regulated so that maximum lift is produced according to a velocity of flow based on the direction of a water flow, lift is produced in a direction extending at right angles with the direction of a water flow. This enables energy saving operation, to be performed.
