Abstract: PROBLEM TO BE SOLVED: To estimate the delay time of a circuit of a hierarchical structure in a short time by preparing the timing model of a module or producing the model before its simulation and calculating the delay time at a level set in the module. SOLUTION: The timing model of a module is prepared or produced before its simulation and the delay time is calculated at a level set in the module. A timing model generation part 5 of this simulation device generates a timing model of the module that is extracted at a module extraction part 2 if the timing module is not registered in a library 3. A timing model registering part 6 registers the generated timing model in the library 3. A simulation part 7 simulates the operation of a circuit by making use of the timing model of the module that is previously registered in the library 3, the generated timing model of the module and the timing model of a primitive cell that is registered in the library 3.

Title: Single lens reflex camera
Inventor: AIHARA YOSHIHIKO
IPC: G03B17/00
Filed: 1988-10-04
Abstract: PURPOSE:To reduce the time lag of release from the release of a shutter to the start of exposure by retreating a submirror for diaphragm driving or range- finding outside the optical path of photographing when the range-finding operation is finished and releasing the shutter after that. CONSTITUTION:The AF range-finding and photometry are executed by turning on the first switch of a releasing button and the submirror 70 for range-finding is made to be down and retreated outside the optical path of the photographing by the normal rotation of a first motor when a lens is focused. On the other hand, when the lens is focused, a diaphragm 530 is stopped down to a prescribed diaphragm value by the turning of a third motor M3. After that, the exposure operation is executed without the time lag of release by turning on the second switch of the releasing button. Besides, since light transmitted through the lens is inducted to a finder optical system by a fixed semi-transparent mirror 71 and the transmitted light of the mirror 71 is used for the photographing, an object can be continuously observed by a finder even when the preparation of the photographing such as the driving of the diaphragm and the submirror 70 or the like are previously executed.

Title: Operation controller for fluidized-bed combustion device
Inventor: FUJIWARA NAOKI
IPC: F23C10/28
Filed: 1987-10-07
Abstract: PURPOSE:To keep stabilized fluidized condition for a long period of time, by a method wherein the title controller is provided with a rough grain ash detecting means, detecting the containing rate of rough grain ash in fluidized medium, and a control means, regulating the extracting amount of the fluidized medium in accordance with the containing rate of the rough grain ash. CONSTITUTION:A part of fluidized medium, collected by a sampling tube 19, is devided into two kinds of rough grain ash and fine grain ash while a rough ash counter 25 and a fine ash counter 26 output a fine ash weight signal 28 and a rough ash weight signal 29. A weight ratio measuring device 18 obtains the rate H% of the rough ash from the fine ash weight signal 28 and the rough ash weight signal 29. When the rate H is larger than the set value of 75 weight %, a motor 37 is driven to throw grain size regulating powder 10 from a powder supplier 11 into a fluidized bed and reduce an average grain size in the bed 3 quickly. When the rate H is between the set values of 25 weight % and 55 weight %, the discharging amount of the fluidized medium from an ash extracting tube 7 is controlled so as to be increased to prevent the grain size of the fluidized medium in the bed from being increased. When the increasing of the grain size can not be restrained by maximizing the extracting amount from the ash extracting tube 7, the supplying amount of sludge ash 5 is controlled so as to be reduced.

Title: Breakage sensing device for fuel cladding pipe used in nuclear reactor
Inventor: SUDO TAKAYUKI
IPC: G21C17/07
Filed: 1990-09-25
Abstract: PURPOSE:To sense destruction of the fuel after its service and judge whether this destroyed fuel is fuel in the reactor core or fuel after service, by sensing destruction on the basis of the concentration of a radioactive fission product gas contained in a cover gas and the concentration of a stable fission product gas. CONSTITUTION:A concentrated fission product gas is sent to a mass- spectrometric device 16 via a piping 15, and the amount of each nuclide of the radioactive fission product gas and stable fission product gas is determined. The result is fed to a calculating/judging device 18 as the mass-spectrometric output 17. This calculating/judging device 18 judges that there is a destruction in accordance with the amount of each nuclide being over the background level and also calculates the ratio of the amount of radioactive fission product gas nuclide to the amount of stable fission product gas nuclide. The obtained ratio is compared with the corresponding value at the time of fuel replacement, and if the former is greater than the latter, it is judged that the fuel assembly 6 in the reactor core region 5 has destroyed, if smaller, judged that the fuel assembly after service in an intra-reactor fuel storing trough 3 has destroyed.

Title: Photoelectric conversion device
Inventor: SUGAWA SHIGETOSHI
IPC: H04N5/335
Filed: 1985-11-13
Abstract: PURPOSE:To inject carriers timely to a control electrode region, and to prevent the generation of an after-image phenomenon by forming a semiconductor region having the same conduction type as a main electrode region in a semiconductor transistor and low impurity concentration in the control electrode region and shaping diode structure together with the control electrode region. CONSTITUTION:A semiconductor region 6 having the same conduction type as a main electrode region and impurity concentration lower than the main electrode region is shaped in a control electrode region 4 apart from the main electrode region. Since diode structure is formed by the control electrode region 4 and the semiconductor region 6, proper voltage is applied to the semiconductor region 6, thus injecting carriers into the control electrode region 4. Consequently, the potential of the control electrode region 4 can be increased sufficiently on the starting of refresh operation, thus bringing the potential of the control electrode region 4 on the completion of refresh operation to a desired fixed value. Accordingly, the generation of an after-image phenomenon is prevented. Even when the titled device is irradiated with intense beams, excess carriers are removed through diode structure, thus obviating the generation of a blooming phenomenon.
