Title: Water leakage detector
Inventor: KODATE HIDEMI
IPC: G01M3/24
Filed: 1981-07-14
Abstract: PURPOSE:To detect the presence and the position of water leakage accurately by providing a water leakage detector hiving a directivity in the sensitiveness integral with a flowmeter. CONSTITUTION:The body 1 of a flowmeter is connected to a water supply pipeline with an outlet and inlet flanges 2 and 3. An electric part box 4 incorporates a flow rate indicator, a terminal plate, an arrester and the like while a pressure-electricity converter 5 having a directivity to detect a water leakage vibration is provided inside the body 1. Output signals of the converter 5 are inputted into a band filter 9 after amplified with a mplifier 8 and only a high frequency vibration component of a water leakage sound is outputted. The output of the filter 9 is inputted into a peak valve discrimination circuit 10 and an output signal is outputted to a decision circuit 11 when the peak value of the vibration component above the specified value. The decision circuit 11 determines whether or not the output of the discrimination circuit 10 lasts for a sprcified period of time by counting outputs of a clock pulse generation circuit 12. When they last for the specified period time, it decided that there is a water leakage. Outputs of the decision circuit 11 are stored in a memory circuit 13 and indicated on a display 14.

Title: Combustion apparatus
Inventor: YOTSUYA NORIO
IPC: F23D11/24
Filed: 1987-05-06
Abstract: PURPOSE:To reduce soot and foul odor at the time of ignition and fire extinction by the reduction in the number of on-off operations of a fuel supply pump when a small amount of hot water is supplied by a method wherein a partition plate is placed in a vaporization cylinder and at the side of the cylinder under the plate, dense air-ports of which arrangement is more dense than that of the other air ports are installed. CONSTITUTION:In response to the reduction in the amount of fuel supply with a fuel supply pump 18, combustion air supplied from the air ports 5a of a vaporization cylinder 5 is reduced, however, the proper amount of air which is necessary for combustion is mainly supplied from dense air-ports 11 placed at the lower air passage 5d of the cylinder 5 and mixed air ports 5e. Rising air-fuel mixture collides with a large amount of air streams ejecting in the radius direction of the ports 11 placed above the passage 5d to burn quickly. The flame holding property at the ports 11 is improved and superior to that at the other ports 5a, 5e by the flame holding force between adjacent flames. Since the ports 11 are installed toward the upper part of an auxiliary combustion cylinder 12, the unburnt part of combustion gas ejecting from the inside of the cylinder 12 is completely burnt by combustion flames 21 formed at the ports 11.

Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To reduce a call loss and to prevent the unnecessary transmission of a radio wave by mapping at least one between information transfer capability and information transfer rate, which are noticed from a telephone line network, in a message when a master machine transmits the message. SOLUTION: When a user A16 calls data, a master machine receives an incoming call from a public network and transmits an incoming call message to a slave machine. A calling number is inputted to an area as a PS number and information transfer rate and information transfer capability are noticed to the bit of the message. When the calling number is shorter with respect to the PS number area of the incoming call message, it is buried with a filler and the area is mapped. The slave machine receiving the incoming call message from the master machine judges whether it can correspond to the communication or not and decides whether a ringer is to be rung or not. Only the slave machine whose incoming call message reaches the fastest to the master machine among the slave machines in which the ringer rings starts communication.

Title: Gate clogging detector of mold for molding resin
Inventor: KAGAWA IKUNORI
IPC: B29C45/26
Filed: 1989-04-28
Abstract: PURPOSE:To discriminate whether gate clogging such that a molding resin remains in a gate is generated corresponding to the change state of air pressure by mounting a pressure detection means for detecting the pressure of the air supplied into a runner through an air supply passage in such a state that an opening and closing valve is opened. CONSTITUTION:For the sake of detecting whether gate clogging is generated by the remaining of a molding material 16 in the submarine gate 5 of a lower mold by a gate clogging detector, air for detecting gate clogging of predetermined pressure is supplied into a communication pipe 6 from an air supply source in such a state that an upper mold 1 and the lower mold 2 are clamped prior to performing injection molding. When an opening and closing valve 8 is moved to an open position corresponding to the pressure of said air, the air passes through an air supply passage 7 to be supplied into a runner 3. In case of clogging, the air enclosed in the runner 3 rises to the emitting pressure of the air supply source at an early stage. By comparing the rising speed of air pressure calculated based on the detection value of a pressure detection means 14 with a reference speed preliminarily obtained by calculation by a discrimination means 15, it can be discriminated whether gate clogging is generated.
