Patent JP-H01253397-A (JP)
Title: Acoustic device
Inventor: YOKOYAMA KENJI
IPC: H04R3/04
Filed: 1988-04-01
Abstract: PURPOSE:To make the Q value of the resonance of a resonator extremely higher and to miniaturize the resonator and, at the same time, to realize a sufficient accoustic radiating capacity by driving a vibrator provided with an active diaphragm for driving the resonator in such a way that the atmospheric reaction from the resonator produced when the resonator is driven can be compensated. CONSTITUTION:A resonator 10 provided with a passive diaphragm 11 acting as a resonantly radiating section is used and a vibrator 20 composed of an active diaphragm 21 and converter 22 is fitted to the resonator 10. Then a vibrator driving device 30 is connected to the converter 22. The converter drives the active diaphragm 21 in faithfully responding to a driving signal from the device 30 and independently gives driving energy to the resonator 10. When the resonator 10 is driven, the atmospheric reaction is applied to the front of the diaphragm 21 from the air in the cavity of the resonator 10, but the device 30 drives the vibrator 20 so as to compensate the reaction. Therefore, the active diaphragm 21 becomes the equivalent wall of the resonator 10 and the Q value of the resonance of the resonator 10 becomes infinitive ideally. As a result, sounds of sufficiently high sound pressure are resonantly radiated from the passive diaphragm 11 acting as a resonantly radiating section.

Patent JP-H05288199-A (JP)
Title: Siphon type pump
Inventor: MIYAUCHI SUNAO
IPC: F04F10/00
Filed: 1992-04-03
Abstract: PURPOSE:To shorten the time required for the formation of a siphon by providing a current plate for partitioning the inside of a discharge pipeline into an upper passage and a lower passage, in the vicinity of the top part of the discharge pipeline, and providing a communicating hole for communicating the upper and lower passages with each other, on one downward side of the current plate. CONSTITUTION:At the time of forming a siphon, water flow flowing over the top part 5a of a discharge pipeline 5 mainly flows in a lower passage 11b, and air remaining in the discharge pipeline 5 stays in an upper passage 11a. The flow speed in the lower passage 11b therefore becomes fast so as to form the siphon easily with small flow in the lower passage 11b. At this time, the water flow flowing in the lower passage 11b comes to have negative pressure at the time of flowing downstream going over the top part 5a, so that the air remaining in the upper passage 11a is sucked into the flow through a communicating hole 13 and flows toward a discharge drum communicated with the lower end of the discharge pipeline 5. The air staying in the upper passage 11a is thereby discharged in a short time, and the siphon is formed easily also in the upper passage 11a. The formation of the siphon in the whole passage is thereby achieved in a short time.

Title: Fuel injecting device for internal combustion engine
Inventor: IRIE YASUTAKA
IPC: F02M59/10
Filed: 1989-04-03
Abstract: PURPOSE:To prevent the occurrence of secondary injection and to prevent the occurrence of cavitation by a method wherein a spring energized in a direction in which a small piston is pulled back is provided, an injection fuel delivery passage to suck back fuel in a high pressure injection pipe installed on the downstream slide of a pump actuating chamber is provided and a series oil passage is formed in parallel with the injection fuel delivery passage. CONSTITUTION:When a small piston 3 is raised by means of a service piston, fuel oil in a pump actuating chamber 15 is pressurized and a check valve 21 is moved upward against a spring 22. The check valve is moved to a position above a collar 21a or a seat 31 and opened, and fuel oil is injected to a cylinder through an injection nozzle by means of a delivery passage 30, a passage 32, and an injection pipe. In this case, a check valve 25 and a chuck valve 23 close seats 19 and 34 by means of an internal pressure. When necessary fuel is injected, upward movement of the piston 3 is stopped, and a pressure in a pump chamber 15 is rapidly reduced to close the valve 21. When a pressure wave in a pipe higher than the opening pressure of the valve 25 returns to the passage 32, the pressure wave is propagated through a throttle 33 to the valve 25, fuel oil is sucked back through the oil passage 32 and the valve 25 is closed, resulting in prevention of the occurrence of secondary injection.

Abstract: PURPOSE:To implement high speed, broad band or high integration density, by providing a second metal film, which is connected to a third metal film and forms a junction between edges, so that the junction is coupled with a first metal film through a tunnel barrier at the side surface of the first metal film. CONSTITUTION:A first metal film 1 and a third metal film 7, each having a specified shape, are formed on the surface of an insulating substrate 5. An insulator 4 having a specified shape is intersected with the first metal film 1 and the third metal film 7. The second metal film 2 is formed on the side surface of the insulator 4 and connected to the third metal film 7. The metal film 2 forms a junction between edges. The junction is coupled to the first metal film 1 through a tunnel barrier at the side surface of the first metal film 1. Thus a tunnel junction 3, which is not affected with the machining accuracy of lithography technology and has a minute junction area and an electrode that can be readily led out to the outside, is obtained. Thus, high speed, broad band or high integration density can be readily implemented in the tunnel junction type solid-state electronic device.

Title: Treatment of silicon surface
Inventor: HAYASHI YUTAKA
IPC: H01L21/306
Filed: 1989-03-31
Abstract: PURPOSE:To eliminate impurities on the surface of a silicon substrate efficiently by setting a temperature of a silicon sample above one for flocculating and accumulating gas which is not excited on the surface while supplying gas which is excited over a specified amount of time and then by keeping the temperature below the one for decomposing non-excited gas. CONSTITUTION:A silicons ample which is to be subjected to surface treatment (either crystal or amorphous system) is retained within a pressure-reduced non- oxidizing environment. In that state, while heating the silicon sample, gas obtained by exciting silicon fluoride, etc., is supplied to the surface of the silicon sample. In this case, heating temperature of the silicon sample exceeds the temperature where the non-excited gas is flocculated and accumulated on the surface of the sample but the temperature where the non-excited gas is decomposed should be selected under the following temperature range. Thus, gas excited under a relatively low temperature environment shows a sufficient washing and protection effect for the surface of the silicon sample. Therefore, it is possible to perform surface treatment of silicon and to eliminate impurities such as oxygen, carbon, etc.

Filed: 1991-03-20
Abstract: PURPOSE:To enable reproduction of entire code data even when a part of a bar mark not legible and the code data are not readable by making plural bar marks represent one code data and incorporating the code data in a complete form in the recording contents of each bar mark. CONSTITUTION:It is assumed that an ID code is '1011'. A bar mark is formed by writing the ID code '1011' twice and a bar mark 2b is formed by writing the code once.

Title: Offset eliminating amplifier circuit
Inventor: NAGABORI TAKESHI
IPC: H04B10/40
Filed: 1995-04-07
Abstract: PURPOSE: To effectively eliminate offset by providing an offset eliminating amplifier circuit having a wide dynamic range on the small chip area of an integrated circuit. CONSTITUTION: Signals inputted to terminals A and B are inputted through an offset controller 1 to a limiter amplifier 2. This amplifier 2 is an amplitude limiter amplifier, amplifies the signals and slices their amplitudes with a constant value. Next, an offset detector 3 compares the average value of output signals at a terminal C with the central value of output signals at a terminal D and the mirror amplification of this error signal is performed. This mirror amplifier gets an average time value depending on a time constant CR decided by input resistor R and feedback loop C. When the input signal is a signal at an average rate 50%, the average values of output signals at the respective output terminals C and D are equal so that it can be detected by watching this difference, namely, the error signal whether offset is normal or not.
