Title: Wake display device
Inventor: YOSHIOKA SHUICHI
IPC: G01C21/00
Filed: 1985-03-27
Abstract: PURPOSE:To display many areas of sea as a detailed chart by accumulating the position data received from a navigation device and providing a wake storing means storing the data as a wake and a display device or the like displaying the wake. CONSTITUTION:When the desired chart is indicated by a keyboard 5, a CPU 3 calculates a scope number of a video disc device 1 corresponding to the specified chart and outputs its information to the device 1. Hereby, the device 1 reproduces a still picture image. A video signal of this still picture image is outputted to a synchronizing signal separating circuit 7 and the circuit 7 outputs a synchronizing signal from the video signal to a CRTC 15 or a CRT 4. On the other hand, the video signal is further outputted to a mixed circuit 9 and respective chrominance signals of red, green and black are added respectively and outputted to the CRT 4. Further, the sailing position data from the navigation device 2 are stored in a RAM 11 and display information displaying the wake is written in a memory 14 for displaying. Then, the CRTC 15 reads display information from the memory 14 and outputs it to the circuit 9. Thus, the still picture image and display information are displayed on the CRT.

IPC: B21C29/00
Filed: 1990-03-16
Abstract: PURPOSE:To stably perform optimum heating and improve working accuracy by setting a heating target temperature on the basis of the deviation between the calculated value of outer surface circumferential average temperature of a billet inserted to a final heating furnace and the outer surface measured temperature value. CONSTITUTION:Before a billet 7 is inserted to a final heating furnace 5, the billet circumferential temperature distribution is measured by a thermometer 11, and the circumferential average temperature is calculated by an arithmetic device 12. The billet 7 is then inserted to the heating furnace 5, and the temperature of the billet 7 is measured by a thermometer 9 prior to the start of heating. A monitor device 10 calculates the deviation between the measured temperature result of the thermometer 9 and the average temperature of the device 12, corrects the target heating temperature for every size and material of the billet 7 to set a monitor target temperature value of the thermometer 9, and controls the heating according to this temperature. The heating temperature of the final heating furnace is stably controlled to the optimum, whereby working accuracy can be improved.

Title: Controller of transistor inverter
Inventor: TSUBOI KATSUTAKE
IPC: H02M7/48
Filed: 1985-03-29
Abstract: PURPOSE:To effectively perform the momentary restarting operation of an inverter by providing a memory for storing a signal from a low voltage detector and a safety operation voltage detector. CONSTITUTION:An AC power source 1 is rectified by a diode bridge 2 and converted into a DC, which is PWM-controlled by an inverter 5 through a reactor 3 and a capacitor 4, converted into an AC, which is in turn applied to a load 6.

Title: Signal-line driving circuit
Inventor: NAGATA HISAO
IPC: H03K19/0948
Filed: 1980-05-19
Abstract: PURPOSE:To reduce noise voltage induced on a signal line, by connecting a transistor (TR), conducting with a small current when it is not selected, to the signal line extending to the output of a driving circuit. CONSTITUTION:When input terminals 11 and 12 of TRs 1 and 2 are not selected, the TRs 1 and 2 are off. However, TRs 21 and 22 are both turned on, so a voltage at an output terminal 13 is equal to that obtained by dividing a power voltage through TRs 21 and 22. Either one of the TRs 1 and 2, when selected, turns on. At this time, although the TRs 21 and 22 are still on, the current of the TR1 or 2 is much greater and influences of the TRs 21 and 22 can be ignored. Thus, adding the TRs 21 and 22 to a conventional signal-line driving circuit turns on both the TRs 21 and 22 even when the driving circuit is not selected, so the output has infinite impedance, reducing noise voltage induced on a signal line 3.

Title: Deoxygenating agent
Inventor: MORITA MASAHIRO
IPC: B01J20/22
Filed: 1979-05-30
Abstract: PURPOSE: To enhance the performance of a deoxygenating agent by having it include defatted soybean or defatted rice bran, or both of them, concentrated aqueous NaCl solution, stone powder, powder of cast iron of a specific content of carbon, and NH 4 Cl.  
     CONSTITUTION: A deoxygenating agent consists of one or more of defatted soybean and defatted rice bran, concentrated aqueous NaCl solution, powder of cast iron containing 3.5W4.5wt% of carbon, and NH 4 Cl, as basic composition. In this composition, the concentrated aqueous NaCl solution is prevented from exuding as the deoxygenation proceeds, because it is adsorbed by the defatted soybean or defatted rice bran. If said NaCl solution is a saturated solution coexisting with solid NaCl or if active carbon coexists as filler, the effect of deoxygenation is further enhanced. This deoxygenation agent in powder form is packed in an air-permeable bag in a given amount, the required number of which are sealed in a non-permeable bag and stored or delivered.

Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To lower the radiated heat of a pressure roller and to excellently retain heat by providing a frame body intervening between 1st and 2nd members and constituting hermetically sealed space for heat insulation. SOLUTION: The lower half of a press roller 3 is surrounded by an aluminum plate 21 being a heat insulating member as a 1st member, and the surface of the plate 21 is finished to be a mirror surface. The plate 21 is supported by a mold member 22 being a supporting member as a 2nd member. A rubber frame 23 functioning as the frame body and having low heat conductivity intervenes between the outer peripheral parts of the plate 21 and the member 22 and constitutes the hermetically sealed space for the heat insulation. At the time of fixing, the plate 21 is warmed by the heat of the roller 3 but the heat is insulated by the rubber frame 23 having the low heat conductivity and an air layer in the hermetically sealed space part. Therefore, the heat of the plate 21 is not directly transferred to a fixing unit frame 1A and the radiated heat amount is made small.

Abstract: PURPOSE:To prevent the frequent fluctuation of a cylinder number for fuel cut by substantially preventing an increase in the number of cylinders for fuel cut until the elapse of the predetermined time when the calculated value of the cylinder number for fuel cut increases due to a transient cause. CONSTITUTION:When a means M5 detects the acceleration slip of a driving wheel M2 in an internal combustion engine M1 having a plurality of cylinders, the target torque of the internal combustion engine M1 is calculated with a means M16.

Abstract: PURPOSE:To make a desired micro-gravity generable with good reproducibility in a zero gravity experiment to be performed nearby the ground by constituting it so as to support a zero gravity tester on a turntable and to perform an agravic test with the desired micro-gravity value. CONSTITUTION:In a micro-gravity generator 10 capable of generating micro- gravity in a zero gravity environment, it is composed of a turntable 12, a turning shaft 14 attached to this turntable 12, an electric motor 16 rotating this shaft 14 and a controller 18.
