Title: Hot water supply device
Inventor: KUNIMOTO KEIJIROU
IPC: F24H1/10
Filed: 1982-08-18
Abstract: PURPOSE:To form an energy saving hot water supply device with no running-out of hot water by a control method wherein a small capacity hot water storage type hot water supply container is connected in series to a tap-controlled hot water supplier or by-passed by means of a three-way valve (a). CONSTITUTION:A control valve 14 is actuated so as to form a circuit B bypassing the hot water storage type hot water supply container 4 by communicating a bypass circuit 13 to the tap-controlled hot water supplier 1 when the temperature Ta of hot water from the tap-controlled hot water supplier 1 is higher than T3, and, on the contrary, to flow a circuit A constituting a circuit to connect the tap-controlled hot water supplier 1 with the hot water storage type hot water supply container 4 in series by communicating a continuously connecting circuit 8 to the tap-controlled hot water supplier 1 when Ta is lower than T2. Because the tap-controlled hot water supplier 1 and the hot water storage container 4 are connected with each other in series at the start of hot water supply, not so much time is taken to raise the temperature of hot water to feed. Furthermore, because the hot water storage type hot water supply container 4 is bypassed when the temperature of hot water from the tap-controlled hot water supplier 1 is raised, the hot water storage volume of the hot water storage type hot water supply container 4 can be mde smaller resulting in reducing the radiant loss from the surface of a hot water storage tank.

Title: Disk device
Inventor: MIYAUCHI HIROSHI
IPC: G11B19/02
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To unnecessitate a stop reference part and to exactly stop a tray at the stopping position. SOLUTION: After the position corresponding to a selected placing part for the CD tray is detected (step 236) by a sensor, the setting is made to B=x (step 238) and A=y (step 240) and also the decision is made (step 242) whether A>=4B or not, and when it is affirmative, the speed of CD tray is reduced (step 244) and stopped (step 252). Consequently, the erroneous detection is eliminated even in the case the rotating speed of the CD tray is changed in accordance with surrounding environments, since a pulse width outputted from the sensor is updated every time by a microcomputer to stop the rotation of the CD tray by taking a multiple of the pulse width detected just before as the reference, then the CD tray is stopped surely at the stopping position, and also the conventional stop reference part is unnecessitated, and the space saving is attained.

Title: Control device for internal combustion engine
Inventor: KURODA OSAMU
IPC: F01N3/20
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To purify toxic component such as NOx from lean burn exhaust gas by estimating NOx exhaust amount during a lean operation by means of a control unit and by setting a fuel injection condition so as to maintain reducing agent whose amount is equal to or larger than that of oxidant when integrated value of the NOx exhaust amount exceeds a set value. SOLUTION: An exhaust gas purification system is provided with a NOx adsorption catalyst 18, and during stoichiometric operation its three way catalyst function purifies NOx, HC, CO in exhaust gas. During a lean operation, NOx adsorption function purifies NOx. In addition, during the lean operation, NOx purification ability of the NOx adsorption catalyst 18 is always judged. This judgment is derived by integrating NOx exhaust amount from each operation condition, and comparing the integrated value with the upper limit of adsorption amount. As a result, when the NOx purification ability decreases, air-fuel ratio of combustion is shifted to the rich side to recover the NOx adsorption ability of the absorption catalyst. Thus, the exhaust gas can be effectively purified under all engine combustion conditions.

Title: Control method for hydraulic actuator apparatus
Inventor: AOYANAGI YUKIO
IPC: F16H61/40
Filed: 1980-10-17
Abstract: PURPOSE: To improve the braking characteristic for a load and the power recovery efficiency of a hydraulic actuator apparatus by limiting the maximum values of the discharging pressure and the sucking pressure of a hydraulic pump to respective preset values determined in association with the discharging capacity of the hydraulic pump.  
     CONSTITUTION: If an operating lever 21a is operated to a change-over position 21A, a rod of a cylinder 20 is moved rightwardly to increase the magnitude of tilting motion of a pump 2 to cause pressure oil to be discharged from a port 2A. The discharging pressure appearing in a discharging side pipe line A then is introduced to a change-over valve 24 as a changing over pilot pressure. If this pressure reaches a changing over pressure Pc which is determined by the characteristic of a spring 24a and the position of a sleeve 24b then, the change-over valve 24 is changed over. The maximum discharging pressure is equal to the changing over pressure Pcmax when the rod 27 is at the most recessed position of a cam 25. The sucking pressure is also controlled in a similar manner when the load is negative with the operating lever 21a operated to another change-over position 21B.

Title: Radar
Inventor: TAKAHASHI HIDEHIRO
IPC: G01S7/36
Filed: 1979-11-09
Abstract: PURPOSE:To prevent the radar jamming by a simple construction by hitting a simulating radar signal of the second frequency transmitted from the radar with no radarlike operation on a target before a beam wave of the first frequency from the radar in the radar operation to hit the target. CONSTITUTION:A primary first horn 24 is placed on an axis of a reflecting mirror 23, from this horn 24, in a reverse direction to the rotating direction of the radar beam, the second primary horn 25 is placed. To the first primary horn 24, the power of the first frequency carrying out the radar operation is fed, and to the second primary horn 25, the second frequency power is fed to generate beams 21, and beams 22. Thus, to the target, at first, the similar radar signal 42 by beams 22 carrying out no radar operation is incident, then a true radar signal 41 is irradiated. In such a manner, since the target side judges erroneously the similar radar signal to be a true signal, jamming wave to the true radar signal cannot transmitted.

Title: Lan communication system
Inventor: NAKAYAMA ATSUSHI
IPC: H04L12/40
Filed: 1990-06-01
Abstract: PURPOSE:To devise the system such that a trailing flag TF and a leading flag LF are overlapped partly without a time gap and the interference from other node is prevented by setting the LF immediately and sending it when the end of transmission is detected by the TF. CONSTITUTION:When a length RLEN of a reception data is smaller than a reception buffer length LEN, a reception data is subjected to DMA transfer to a memory, and when the end of a packet is detected by a trailing flag TF of the packet, a leading flag LF of an ACK packet is set. After the preparation of transmission, an ACK packet format in which a data is made complete is set during that time. Thus, the flag TF of the detected message packet 4 and the flag LF of the ACK packet 5 are partly overlapped. When the transmission of the ACK packet is finished, the flag TF of the packet 4 is sent and the transmission of the ACK packet is finished to make prescribed communication complete.

Title: Speed controlling method of tail part of strip in hot finish rolling
Inventor: ISHIKAWA SHIYUUICHI
IPC: B21B37/46
Filed: 1979-11-10
Abstract: PURPOSE: To make possible the passage of a stable tail part through the preset volume operation alone, by providing a deceleration rate setter to each stand of rolling mills.  
     CONSTITUTION: The operator judges product size, material quality and rolling conditions and sets volume controls 13, 14, 15 at proper values. For the head part and central part of a coil, mill speeds are finely adjusted, according to need, by means of successive mass controllers 7W9, and the fine adjustment signals of the mass controller are transmitted to mill motors by way of control circuit 1W3, whereby the fine acceleration and deceleration adjustment of the speeds is executed. At the time when the tail part of the strip leaves the (n-2) stand, a relay 4 acts to transmit the preset deceleration rate to the control circuit 1 via a volume control 13. This is then added with the signal from the mass controller 7 and is outputted to the mill motor, and the motor is decelerated by the volume amount. The same holds true of other n, (n-1) stands. When the tail end past-through the (n-1) stand, the relay 4 is reset and the value of the volume control 13 is cancelled.
