Title: Method and device for delaying ultrasonic signal
Inventor: DEIITOMAARU HIRAA
IPC: G01S7/52
Filed: 1985-07-25
Abstract: In medical ultrasonic technology (in particular with phased arrays) it is necessary to delay in time a plurality of received ultrasound signals and subsequently to add them after they are as nearly in phase as possible. The delay times required for this purpose are approximately between 0 and 10  mu s. The ultrasound signal is analyzed as to envelope and a sign. The envelope is then delayed either in analog (e.g. with LC delay lines) or digitally (e.g. with shift registers) through a delay means which is adjustable in coarse time steps of e.g. 500 ns. The sign signal corresponding to the sign of the ultrasound signal is delayed via a digital delay section which is adjustable in small time steps of e.g. 50 ns. Phase coherence to other ultrasound signals can be established. Thereafter the delayed sign signal and the delayed envelope signal are multiplied one by the other in a multiplier. Thereafter the output signal is filtered in a low-pass filter. The output from the low-pass filter then represents the delayed form of the ultrasound signal.

Title: Radio communication system
Inventor: ISHIKAWA TOMOO
IPC: H03L7/08
Filed: 1981-10-16
Abstract: PURPOSE:To decrease greatly the power consumption of a phase locked loop circuit, by having an intermittent locking operation through said loop circuit of a frequency synthesizer and at the same time cutting off the power supply to an optional circuit in the nonlocking mode. CONSTITUTION:A switch 7 is provided to a phase locked loop circuit to open/ close the loop, and at the same time a switch 9 is provided to turn on and off the power supply to at least one of the circuits except a voltage control oscillator 2 among the circuits forming the loop. A storage circuit 11 stores the control voltage. A frequency monitoring means is set to a radio device which is opposite to a radio device containing the circuit 6. Then the switches 7 and 9 are closed to perform a locking operation when a frequency change exceeds a prescribed range. Then the circuit 6 performs an intermittent locking operation. As a result, the power consumption is reduced.

Filed: 1989-06-27
Abstract: PURPOSE:To miniaturize a radio equipment and to simplify the configuration of the radio equipment by providing a band pass filter(BPF), RF power module (for power amplification) and isolator on the same radiation fin. CONSTITUTION:The output terminal of a BPF 3 is connected to the input terminal of an RF power module 1 an the BPF 3 and RF power module 1 are fitted on a radiation fin 2. The input terminal of an isolator 4 is connected to the output terminal of the RF power module 1 and the isolator 4 is fitted on the radiation fin 2. In such a case, since the BPF 3 and isolator 4 are positioned in the vicinity of the RF power module 1, the elements of these equipments are easily connected and the equipments are easily handled. A transmission output step can be miniaturized and the idle space of an external printed circuit board can be effectively utilized. Since the grounds of respective high frequency circuits can be made common, it is possible to prevent trouble such as oscillation caused by the difference of mounting positions.

Title: Decomposition of organic substance in sludge
Inventor: NITTA YOSHITAKA
IPC: C02F11/00
Filed: 1991-06-11
Abstract: PURPOSE:To decompose sludge at low cost by injecting an air containing ozone of comparatively low concentration into sludge. CONSTITUTION:An air containing 100 to 1000ppm of ozone is directly injected into sludge at a sea bed or a water bottom, or sludge is pumped up using an air lift pump 2 with an air containing ozone of the same concentration. Then, the ozone in an aeration air or in an air for air lift attacks selectively a high molecular weight organic substance which cannot be decomposed by bacteria in the sludge, for example, the double-bonded part of higher fatty acid of high molecular weight and cuts the molecular chain to decompose the part partially to a molecule of such size as can be decomposed by bacteria. Thus the bacterial decomposition of the molecule is assisted. If the ozone is of comparatively low concentration, say 100 to 1000ppm, it does not demonstrate sterilization effects upon aerophobic bacteria. Thus sludge can be decomposed at low cost.

IPC: G06F12/10
Filed: 1987-07-03
Abstract: PURPOSE:To contrive the improvement of the operating efficiency of an address conversion buffer by storing an address conversion pair in the address conversion buffer to a storage location corresponding to virtual computer discrimination information. CONSTITUTION:When a memory readout request is generated from a controller CU 101, the address conversion buffer TLB 104 is indexed from its logical address and when the corresponding address conversion pair exists in the TLB, the conversion to a real address is executed by the TLB. When the corresponding conversion pair does not exist in the TLB, a prescribed address conversion operation is implemented by an address conversion unit 102 and the address conversion pair based on the result of conversion is registered in a column in the TLB 104 corresponding to virtual computer discrimination information VMID. Thus, the address conversion information in a host computer and the virtual computer having different VMID is stored simultaneously and the utilizing efficiency of the TLB 104 is improved.

Abstract: PURPOSE:To simultaneously input a three-dimensional co-ordinates value to an electronic computer, by providing a storage register of a height co-ordinates value on a tablet device, installing a button for setting said value, to a stylus pen, and operating it. CONSTITUTION:LINE is inputted from an input device, the button of the stylus pen is turned on, a height co-ordinate value 100 is inputted from the input device, and the button of the stylus pen is turned off. Subsequently, in the stylus pen, points corresponding to 1 and 2 on the tablet are pushed. As a result, three- dimensional co-ordinates values of 1 and 2 are inputted to an electronic computer. Subsequently, since the height is defferent, the button of the stylus pen is turned on, a height co-ordinate value 50 is inputted from the input device, and the button of the stylus pen is turned off. Subsequently, in the stylus pen, points corresponding to 3 and 4 on the tablet are pushed. In this way, those three- dimensional co-ordinates values are inputted. Since LINE is inputted at first, as for 1, 2, 3 and 4, a graphic form which is connected with a segment different in height is inputted to the electronic computer.
