Abstract: PROBLEM TO BE SOLVED: To improve cleanliness of a molten metal without bubble mixing or oxide generation, and stabilize crystal generation and solid phase rate so as to improve casting quality by pouring the metal into a molten cup under a condition that it is inclined, and appropriately controlling the inclination angle while the metal pouring is proceeding. SOLUTION: Under a condition that a molten metal cup 23 is inclined, the metal starts to be poured into the molten metal cup 23 by a metal supplying device, and a piston rod 31a, a cam 12, and the molten metal cup 23 are moved and rotated in a direction shown by an arrow respectively while the metal pouring is proceeding so as to gradually reduce the inclination angle of the molten metal cup 23, till the molten cup 23 is in a vertical condition at the completion time of metal pouring.  At that time, rotation action velocity of the molten metal cup 23 is set to be a desired velocity while controlling descending velocity of the piston rod 31a, but it is desired to control the descending velocity of the piston rod 31a in a way that it is gradually decreased from the start of metal pouring to the completion for the purpose of stabilizing the metal pouring condition into the molten metal cup 23.

Abstract: PURPOSE:To easily produce a maleimide in a high yield and selectivity by using an N-unsubstituted maleamic acid ester as a starting raw material and imidating the ester by dealcoholic cyclization with a monoalkyl or monocycloalkylsulfuric acid ester. CONSTITUTION:This N-unsubstituted maleimide is produced by heating a maleamic acid ester compound of the formula I (R<1> is a 1-8C alkyl or a 3-8C cycloalkyl) together with a mono(cyclo)alkylsulfuric acid ester of the formula II (R<2> is a 1-8C alkyl or a 3-8C cycloalkyl) in an inert organic solvent to effect the dealcoholic cyclization reaction of the ester compound. The amount of the compound of the formula II is preferably 0.01-2mol based on 1mol of the compound of the formula I. The group R<1> of the compound of the formula I is preferably same as the group R<2> of the compound of the formula II. The preferable reaction solvent is, e.g. toluene or xylene. Homopolymerization or copolymerization of the maleimide by radical polymerization provides a heat- resistant thermoplastic resin. The maleimide is also useful as an intermediate for pharmaceuticals, agrochemicals, etc.

Abstract: PURPOSE:To confirm a good condition of control rods in a nuclear reactor, to prevent falling accident of the control rod and to improve safety of the nuclear reactor by measuring continuously weight loads of the control rods using a weight measuring device measuring the loads of the control rods. CONSTITUTION:A thrust receiver 12 which is an electric weight scale (a load cell) provided at a lower part of a driving motor 3, shows a constant load applied onto an axis during a condition where a control rod 2 is not operated, and shows resistance by water in a nuclear reactor and friction force of the control rod 2 rubbing with core internals, as a weight load, when the control rod 2 is inserted or withdrawn. Accordingly, in case that the load cell shows a load larger than normal one when the control rod 2 is inserted into the reactor and a load smaller than normal one when the rod 2 is withdrawn from the reactor, an abnormal contact of the rod 2 with the core internals is indicated. Therewith, by detecting a load change differing from the values of normal insertion and withdrawal, damage given to the core internals can be detected.

Filed: 1985-04-26
Abstract: PURPOSE:To make possible to obtain high developed color density, by forming a coating layer containing pigment having specific average oil absorption and a specific volume average particle size on a support and impregnating said coating layer with a dye acceptor.

Title: On-vehicle position detector ad direction identifying device using path side beacon
Inventor: NISHIO MASAHIRO
IPC: G08G1/133
Filed: 1992-04-10
Abstract: PURPOSE:To prevent the erroneous detection of a position and direction due to the influence of a phasing or the like, in on-vehicle position detector and direction identifying device which operates a position detection and a direction identification by receiving a path side beacon signal. CONSTITUTION:At the time of operating the position detection, and a direction identification from a received signal, first of all, the position detection and the direction identification are temporarily validated based on a phase judgement output when the received signal is less than the first reference level (for example, -75dB) (S12). Next, when the received signal is more than the second reference level (for example, -65dB), the temporarily validated position detection and direction identification are established (S6, S10, and S14). Thus, the erroneous judgement of the position detection and the direction identification due to the reception of the signal whose reception level is low along a wide range can be reduced.

Abstract: PURPOSE:To provide an image forming apparatus in which the effect of a cooling fan is not degraded even having used for a long time by controlling an air current generating means to generate first or second air current responding to the temperature detected by a temperature detecting means. CONSTITUTION:When the mode is turned into a print mode based on an print instruction, a fan 18 as an air current generating means is actuated by signals relating to the feeding of paper as sheets such as pick-up signals, etc., for a paper feeding roller 9 and is controlled by a controlling means as to generate second air current which suck outside air to the inside of a main body I. When no print instruction is given, the main body 1 is shifted to a waiting state, that is the stand-by mode, and at that time, the fan 18 is so controlled as to generate first air current to discharge the air inside the main body I to the outside. In this way, the fan 18 is switched to air suction and air discharge state based on the print mode and stand-by mode, so that the temperature rise of the paper and the inside of the apparatus at the time of printing can be prevented efficiently.

IPC: G11B7/09
Filed: 1980-07-04
Abstract: PURPOSE:To obtain a tracking compensation signal from the reflected light which is caused by irradiating a light beam onto a track that is recorded on a preceding track turn. CONSTITUTION:The light from a record light source 5 and modulated by an FM modulator 15 is divided into three beams by a divider prism 6. The outer two beams of these three divided beams are irradiated on a disk 2 after passing through light diminishing filters 9 and 10 to perform the recording at a beam spot 18a and irradiate a part of the recorded track preceding by one track at a beam spot 18c. The reflected light from the spot 18c receives a modulation from the modulator 15 and modulation due to a partial irradiation of the recorded track. Furthermore the amplitude of the reflected light is proportional to the rate with which the recorded track is irradiated. Thus the upper side wave band of the output of a detector 11 is excluded, and the output signal of a detector 12 is compared with the signal that is properly amplified by an amplifier 44. As a result, the tracking compensation signal is obtained at a terminal 53.

Title: Picture motion information signal generating circuit
Inventor: KUDO KOJI
IPC: H04N7/01
Filed: 1988-04-15
Abstract: PURPOSE:To suppress a pseudo motion signal to be easily generated in a picture frame part by preparing many types of different motion detecting sensitivity features beforehand, providing a contour information signal generating circuit, and switching the motion detecting sensitivity features with the use of a control signal outputted from a generating circuit. CONSTITUTION:Features 1-4 are prepared as nonlinear converting features beforehand. Four types of control signals are outputted according to levels from a contour information signal generating circuit 13. The nonlinear converting feature selected by the control signal generated when the maximum contour signal is obtained is the feature 4. As the contour signal become smaller, the feature 3, the feature 2 and the feature 1 are selected, corresponding processings are executed, and outputted by a nonlinear converting processing circuit 9. Especially in the still video, when the deflection of a television camera or the jitter of a synchronizing system exist, the pseudo motion signal is generated in the picture edge part even when the motion does not exist. The pseudo motion signal in the edge part can be suppressed by controlling the nonlinear converting processing feature according to the size of the contour signal.
