Title: Device for detecting low power in at least one cylinder of multicylinder engine
Inventor: FUEFUEN TEII TAO
IPC: G01L5/00
Filed: 1994-06-30
Abstract: PURPOSE: To specify a cylinder which is in a low power condition including misfire under on-road driving condition by monitoring the resonance frequency of each of cylinders using a vibration sensor, and detecting an abnormal resonance frequency as an indication of operation at an inappropriate power level. CONSTITUTION: An engine 1 equipped with the low power detecting device has vibration sensors 3 mounted on valve housing covers 5 located near respective cylinders. In order to separate engine vibration related to combustion, time domain processing based on crank angle is performed; i.e., a crankshaft angle indicator 7 such as a timing encoder for a crankshaft 8 is used, and signals from the sensor 3 which are to be processed by a data processor 9 are limited to, e.g. three points that are 30 degrees ahead of and behind the top and bottom dead centers. After measurement signals at the three points are passed through a BPF 11, they are subjected to A/D conversion, and FFT based on the matching of a parabola is performed using the data processor 9 to estimate resonance frequencies.  Then a threshold is provided to detect abnormal resonance vibration to specify a cylinder that is under a low output state.

Title: Electromagnetic induction apparatus
Inventor: MATSUMOTO TAKAHIRO
IPC: H01F27/10
Filed: 1982-08-27
Abstract: PURPOSE:To recycle the heat from a magnet coil and utilize the heat as a heat source by a method wherein a tank of an electromagnetic induction apparatus is separated into a core chamber and a winding chamber by a heat insulating wall and a cooling system is connected to each chamber and the heat is recycled by a coolant. CONSTITUTION:The inside of a tank 11 is separated by a heat insulating wall 12 into a coil chamber 14 in which a transformer 13 is stored and a core chamber 16.Each chamber is filled with insulating oil 30 and is made oil tight each other. A coolant 20 is circulated between the coil chamber 14 and a heat exchanger 60 by a pump 71 and keeps the temperature approximately not more than 80 deg.C. A coolant 30 is circulated between the core chamber 16 and a heat exchanger 80 and exchanges heat with a heating medium 90. The chamber 16 and 14 are separated thermally by a heat insulating material 50 covering the wall 12 and the temperature of the coolant 20 rises independently and the heat is recycled efficiently. With this constitution, the heat from loss generated by the core can be recycled through the coolant efficiently without being limited by the heat resistant temperature of the insulation of the magnet coil, thereby the utilization of the heat lost at the electromagnetic induction apparatus can be realized.

Title: Moving picture holography transmission system
Inventor: HIGUCHI KAZUTO
IPC: G03H1/00
Filed: 1988-06-20
Abstract: PURPOSE:To reduce the transmission information volume without damaging the three-dimensional effect by rotating a filter to a hologram to take out holography information where the transmission direction is successively varied and transmitting this information to the reception side. CONSTITUTION:Holography information is transmitted through only parts corresponding to transparent parts of a filter 20 and is inputted to an image pickup means 7 and is sent to the reception side through a transmission line 8. The filter 20 is successively rotated at a required angle to a hologram 6 for every one-frame components of hologram picture to be transmitted, and the filter 20 is returned to the original angular position after a required number of hologram pictures are transmitted. Consequently, detailed information in all directions can be transmitted by elapse of one cycle though detailed information only in a specific direction is transmitted with one hologram picture. Thus, the time of one cycle is set to a value approximating the after-image time of human eyes to transmit information in all directions with respective hologram pictures, and a picture quality, namely, the three dimensional effect which is not inferior to that obtained at the time of reproducing is obtained.

Abstract: PURPOSE:To detect the presence/absence of an image forming cartridge at a low cost by blocking a detecting means with a stirring and carrying means for detecting the presence/absence of the cartridge. CONSTITUTION:An image forming cartridge makes forward-rotating motions immediately after power supply is made and the motions are continued while a stirring vane 5 makes one turn. When the vane 5 makes one turn, surfaces of light transmissive widows 7 and 8 are cleaned by means of a rubber plate 6 fitted to the vane 5 and the light from a light emitting element 10 can pass through the windows 7 and 8, but the passage of the light is necessarily blocked for a fixed period by the vane 5 and blade 6. Such operations are necessarily carried out one time after power supply is made and states where a light receiving element 9 always receives the light of the element 10, where the element 9 is irradiated by the light of the element 10 by a fixed period, and where the element 9 is not irradiated by the light of the element 10 are detected. Therefore, the presence/absence of the image forming cartridge can be detected.

Title: Classifying circuit for operation speed of electronic component
Inventor: HIROSE YASUNORI
IPC: G01R31/28
Filed: 1991-05-27
Abstract: PURPOSE:To shorten inspecting time by initializing with the second reset signal and latching an output made an incremental operation by a clock signal in the period of the disagreement between the output value initialized by the first reset signal and an expected value. CONSTITUTION:Reset signals RA, RB are generated 1 and a clock signal CKL is generated 2 by a reference timing signal at the time to start a test. A counter circuit 3 reset with the signal RB outputs only an output D0, and a latch circuit 4 reset with the signal RA outputs only an output Q0. Just after setting the input to an electronic component to be inspected, the circuit 3 outputs the output D1 and further D2 making an incremental operation for each input of the signal CKL, in the period of the disagreement between the output value and an expected value where the output is unsettled, and an output P1 and further Q2 latching these are output. If an output value of the electronic component settles and agrees with the expected value the circuit 3 does not change to the input of the signal CKL. Therefore, the operation speed of the component can be classified and that rating can be decided by only one test by reading the output of the circuit 4.
