Title: Forced circulation type solar heater
Inventor: SHINKI KENICHI
IPC: F24S90/00
Filed: 1980-05-15
Abstract: PURPOSE: To reduce the variation in the circulating amount of circulating water due to expansion of the water by providing a float valve in a pipe communicating a circulation circuit with a water supply tank and providing an air-lift pump for pumping water to a circulation tank in the circulation circuit.  
     CONSTITUTION: When the temperature difference between a heat collector 1 and a hot water storage tank 2 becomes large, the variation in the circulating amount of water is reduced by utilizing the pumping action of an air-lift pump 7, and the pumping force of the pump 7 can be maintained constantly because a float valve 8 is provided at a tube 6 at the lower part of a water supply tank 3, with the result that the circulating amount can be maintained constantly regardless of the water temperature. Even if the specific weight of the heated water is varied by the heat collector 1, the water at the bottom of the tank 2 is pumped by the pumping force of the pump 7, thereby preventing the shortcircuit of the tank 3 through the pump 7 with a circulation tank 4.

Title: Analog to digital converting circuit
Inventor: NODA TSUTOMU
IPC: H03M1/20
Filed: 1981-05-01
Abstract: PURPOSE:To improve precision when a digital-analog converter whose precision of the high-order digit bits is inferior is used, by outputting a digital signal consisting of (n+1) bits more than an (n)-bit full scale as an (n)-bit full-scale digital signal of all-0 bits. CONSTITUTION:When a digital signal whose offset is reduced by a digital adder 30 exceeds an (n)-bit full scale, its significant digit bit is a ''1'', which is inputted to the most significant digit bit input 33 of a full-scale discriminating circuit 31. A full-scale discriminating circuit 31 sends a full-scale output of all-1 bits from an (n)-bit output 32. Consequently, even when an analog input signal to an analog- digital converter reaches a large signal level, thus obtaining a digital output signal which is nearly symmetric vertically.

IPC: G01V3/10
Filed: 1981-04-30
Abstract: PURPOSE:To detect a conductor or a magnetic body of a metal and the like in a stable and accurate manner by a simple constitution, by detecting the conductor or the magnetic body magnetically based on the change in frequency according to the change in the inductance of two sets of detecting coils. CONSTITUTION:One end of a coil 2 of two sets of detecting coils 2 and 3 on a bobbin 1 is connected to the negative-phase input terminal of a differential operational amplifier 6 earthed through the intermediary of the resistor R1 of a rectangular-wave oscillating circuit 5, while one end of the coil 3 is connected to the positivephase input terminal of the amplifier 6 earthed through resistors R3 and R2. When a body 4 to be detected, a magnetic body, approaches, a rectangular wave whose frequency becomes higher until the body passes the coil 2 and lower thereafter is generated in acordance with the change in the inductance of the coil 2 and 3 from a circuit 9 through the intermediary of the amplifier 6, and the frequency thereof is compared with a set reference frequency by a frequency comparator 10. When the body to be detected is a conductor, a similar process appears, except that the change in the inductance turns reverse. Thus,  stable and accurate detection is performed through the comparison of frequencies without being affected by outside noises, by a simple constitution not requiring an oscillator oscillating continuously and a capacitor.

Title: Network print data management system
Inventor: FUKUNAGA SHINICHI
IPC: H04N1/32
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a print data management system in a network, which is capable of counting, for each user, data print-outputted from a printer connected to a network and usable by a plurality of users, and which is so designed as to be capable of making rational use of this system. SOLUTION: A printer analyzes the top list of received data to ascertain whether it coincides with a host computer ID start notice command set in advance (S1). In the case of coincidence, its ID is set as a user's ID (S2); otherwise no ID is set (S3). Then, if the received user's ID is not listed in the preset corresponding table, the user's ID is added to the corresponding table (S4), and a counter for counting the number of sheets to be printed is set to zero to start the counting of the number of sheets to be printed (S5). When a host computer ID finish notice command is received (S6), the counting is finished, and the number of printed sheets is added to the corresponding table to be registered (S7). In this case, the counting can also be made for every sheet feeding tray in the printer.

Title: Ultrasonic wave transmitter-receiver
Inventor: TONE MASAHIKO
IPC: B06B1/06
Filed: 1984-04-02
Abstract: PURPOSE:To obtain an ultrasonic wave transmitter-receiver where ultrasonic wave attenuation is very less and its acoustic matching layer is protected from dirt and mechanical damage by tensing a protecting film while being adhered to the surface of the acoustic matching layer. CONSTITUTION:The acoustic matching layer 8 is bonded to an ultrasonic wave irradiating plane of a piezoelectric ceramic vibrator 7 and a back load member 9 is bonded to the back side of the vibrator 7. The plastic protecting film 10 is tensed adheredly to the surface of the acoustic matching layer 8 so as not to provide an air layer inbetween. In the ultrasonic wave transmitter-receiver with such structure, the thicker the plastic protection film 10 is, the more the center frequency is shifted toward lower frequency. Thus, in order to bring the center frequency with the protecting film close to the center frequency without the protecting film, the thickness of the acoustic matching layer 10 is formed thinner and the thickness of the protecting film 10 is nearly 0.003 time of the wavelength of the ultrasonic wave propagated in the plastic.

Filed: 1988-03-22
Abstract: PURPOSE:To obtain an optical disk producing little surface oscillation by adhering two disks to which a bonding agent is applied in a pressure-reduced condition to each other in a pressed state under the atmospheric pressure or in a fluid. CONSTITUTION:Two disk base plates 35 and 35 are put on another, with their center holes being matched with each other by means of a center hole matching jog 37, after a hot-melt bonding agent 36 is applied to the base plates 35 and 35 and put on a supporting rod 23.

Filed: 1990-03-16
Abstract: PURPOSE:To obtain the etching device capable of controlling the variance in the line width due to various parameters and capable of controlling the line width with high precision by allowing the device to control etching with the intensity of light transmitted through a sample, namely the optical density of the sample. CONSTITUTION:A resist pattern is formed on a transmissible substrate as shown in the figure to obtain a sample 2. When the sample 2 is etched in a liq. etchant 4, the sample 2 is irradiated with the light from a light source 5. The light from the light source 5 is detected by a detection part 6 through the sample 2, however the light is weak at the detection part 6 at the start of etching. As the etching proceeds, only the substrate is left in the sample 2, and hence the intensity of the light to the detection part 6 is increased. Namely, the variation in the optical intensity of the sample 2 is detected by the light intensity detected at the detection part 6, and etching is finished when only the transparent substrate is left.

Filed: 1982-04-20
Abstract: PURPOSE:To facilitate laser trimming by using a metallic layer of a high melting point as a base for forming electrodes of a metal of high conductivity on a piezoelectric body. CONSTITUTION:The counter electrodes 13 are formed on the opposed main surfaces of the piezoelectric body 12 made of lithium tantalate. The electrodes 13 are formed by laminating conductor layers 15 of high conductivity metal such as gold and silver on the base material layers of high melting point metal such as tungsten, tantalum, and molybdenum. For adjusting a resonance frequency, a part of the electrodes 13 is irradiated with a laser spot to form a perforation 16. Consequently, the conductor layer 15 is vaporized, but the base material layer 14 is held below its boiling point, so a part of the base material layer 14 remains as it is. Consequently, evil influence upon the piezoelectric body 12 is prevented to improve the reliability to a secular change and adjustment precision.
