Title: Heat exchanger provided with shot cleaning device
Inventor: UCHIDA SATOSHI
IPC: F28G1/12
Filed: 1987-03-30
Abstract: PURPOSE:To make inert gas unnecessary and improve safety, by providing a hopper, employing water, instead of a lock hopper for pressurizing gas to pressurize a vessel by employing water. CONSTITUTION:Steel balls 24, stored in the separate filter of a receiving hopper 5, are dropped into a supply hopper 7 by opening an air-tight valve 6 and filling water. In this case, the steel balls 24 are stored on the separate filter in the supply hopper 7. Water is supplied by a feed water pump 9 into the supply hopper 7 through a water feeding valve 10 while the air-tight valve 6 is closed in the condition of full of water, in which the water overflows into the receiving hopper 5. Further, the supply hopper 7 is pressurized by employing the feed water pump 9 until the hopper 7 is pressurized by water to a pressure same as the gas pressure in the heat exchanger 2. Subsequently, an equalizing valve 11 is opened, then a water blow valve 12 is opened to drop water in the supply hopper 7 into a lower water tank 13. According to this operation, the steel balls 24 may be separated from water by the separating filter. next, a supply valve 14 is opened to drop the steel balls 24 into a heat exchanging unit 3 to effect soot blow, thereafter the steel balls 24 are retrieved into the lower water tank 13. Subsequently, water is supplied to discharge the gas in the heat exchanger.

Title: Electric power supply
Inventor: FURUYA KENJI
IPC: H02H7/04
Filed: 1990-03-23
Abstract: PURPOSE:To protect each circuit on the load side surely from burning or other troubles by controlling the output current when an overcurrent occurs and by cutting off the output current when the overload condition continues longer than a set period of time. CONSTITUTION:The output load is detected by a detective coil 7c. A control section 4 detects a load current and sends the detection result to an oscillation control section. The oscillation control section turns a transistor 11 in a switching section 5 ON and OFF and controls the conduction of a current which flows in a primary coil 7a of a transformer 7. In the case that an overcurrent flows, the output voltage is decreased by the current control of the transistor 11 followed by the cutoff of the output. Afterwards, the output current does not flow even after the load is recovered. Reclosing is made possible by resetting the lock state at a hold section from outside.

IPC: G01B11/24
Filed: 1993-03-09
Abstract: PURPOSE:To allow accurate, automatic, noncontact detection of deformation of framework in safety by comparing effective length and two crossing angle of each arm in the framework calculated through image processing with those of normal framework. CONSTITUTION:When the vehicle advances into a garage, a shoedetecting section detects a shoe and an ITV control section 71 outputs a control signal. An ITV camera 62 picks up the image continuously and when a framework arrives at a predetermined position, a control signal is inputted and an image data at that time is stored 722. An image processing section 721 reads out image data from a memory 722, calculates athreshold value Ls and binarizes the Ls, and then extracts the outline (r) of each arm thus calculating each approximation line Rc. Furthermore, a linear equation for the line Rc is determined and the coordinates of eight cross points are determined according to each linear equation and then the lengthof each approximation line, i.e., the effective length of each arm, is calculated based on the difference of coordinate between two cross points and stored 722. Two cross angles are also calculated for each right and left cross point and stored 722. Each data thus calculated is compared 723 with normal.

Title: Method for improving fuel consumption of on-vehicle internal combustion engine
Inventor: NAKANO KENJI
IPC: F02D21/08
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To control the reflux of the exhaust gas so as to appropriately maintain the mean effective pressure of the cylinder-inside pressure of an internal combustion engine by correcting a set value of the exhaust gas reflux on the basis of the mean effective pressure of the cylinder-inside pressure computed per each engine cycle in the predetermined traveling condition. SOLUTION: An open degree valve reference value θEGRO of an exhaust gas re-circulating device(EGR) is decided on the basis of a traveling parameter (S101). A first predetermined value a1 (Ne) is decided on the basis of the engine speed Ne of an on-vehicle internal combustion engine (S102). Continuously, a present value Pmi as a mean effective pressure of the present engine cycle is computed (S103). This present value Pmi and the first reference value a1 (Ne) are compared with each other (S104), and in the case where the present value Pmi is more than the first reference value a1 (Ne), an EGR corrective coefficient KEGR is increased by the predetermined value ΔKEGR so as to increase the quantity of the EGR (S105). Thereafter, open degree of an EGR valve is controlled on the basis of the corrected EGR open degree valve set value.
