Title: Ski plate
Inventor: KANAMORI KATSUJI
IPC: A63C5/12
Filed: 1994-01-10
Abstract: PURPOSE:To obtain a ski plate which prevents overdeflection and permits easy turning operation by loosely fitting a reinforcing member having rigidity higher than the rigidity of a ski plate body into the hollow part of this body in such a manner that this member is fixed into the hollow member when the body curves to some curvature or above. CONSTITUTION:This ski plate is formed of the ski plate body 5 and the hollow part 7 formed in this body on the side lower than a neutral axis 2 of a longitudinal bending mold. The reinforcing member 7 having the rigidity higher than the rigidity of the ski plate body 5 is loosely fitted into the hollow part 7 in such a manner that this member is fixed in the hollow part 7 when the body 5 bends to some curvature or above. As a result, the rigidity of the ski plate is increased by the reinforcing member 6, by which the increase of the deflection quantity is so suppressed as not to increase more than needed when the ski plate deflects more than the designed deflection quantity. Suitable deflection is obtd. even if the load in the first half of a turn is small. The ski plate does not deflect more than the designed deflection even if the load in the second half of the turn and, therefore, the deflection of the ski plate ideal in the general turns is obtd.

Title: Manufacture of thermoplastic resin foamed plate and apparatus therefor
Inventor: HAYASHI TOMOSHIGE
IPC: B29C48/305
Filed: 1983-01-28
Abstract: PURPOSE:To contrive to obtain a thick and wide highly foamed plate easily by a method in which the resin discharging end surface of a nozzle is caused to be a curved surface protruding to extruding direction so as to protrude most at its center, and the side of a forming path facing to the head is caused to be a concave surface corresponding to the discharging end-surface. CONSTITUTION:The heated resin molten material containing foaming agent is formed into the flat shape with larger width compared with thickness in a nozzle 3, and is extruded from an orifice and then enters into a forming path 6. Here, the resin material is allowed to expand both in thickness direction and in width direction and is foamed. The discharging end surface 5 of the nozzle 3 is formed into a curved surface protruding to extruding direction if seen from width direction, and then the surface of the forming path 6 facing to the nozzle is formed into a concave surface coinciding with said concave surface. Therefore, the expansion is carried out along the curved surface in width direction, and the resin is advanced in the forming path, while regulating the length both in width direction and thickness direction. Consequently, the wide and thick resin plate foamed at high expansion ratio may be obtained.

Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To allow a remote controller to enable entry operations by automatically displaying an operating state of an installation device, when power supply is applied to the remote controller. SOLUTION: With a battery power supply 2 applied to the remote controller 1, a remote control communication means 3 automatically sends a connection signal to a gas hot water supply device 10. Upon the receipt of a reply signal from an installation device communication means 12 of the gas hot water supply device 10, a display means 6 displays an operating state and the operating state can be changed through the entry by an operation means 7. Since the connection procedure is automatically conducted by having only to supply power to the remote controller 1, the operating state is immediately confirmed by the display means 6 and the setting condition of the operating state is changed by the operation means 7. Thus, the operating state of the installation device is easily changed.

Title: Probe position controller for microscope employing scanning probe
Inventor: SUEYOSHI TAKASHI
IPC: H01J37/28
Filed: 1993-01-29
Abstract: PURPOSE:To allow the holding of a probe at a fixed height by providing a heating power supply for feeding a sample with heating current, means for detecting the voltage of the heating power supply, and means for controlling the bias voltage to be applied between the probe and the sample. CONSTITUTION:A constant current source 15 is connected across a sample 1 through a switch S and the sample is heated to an arbitrary temperature, e.g. 800 deg.C, by feeding a current thereto. Since the voltage of the constant current heating power supply fluctuates to sustain a constant current level, the voltage varies as the resistance of the sample 1 varies until the temperature of the sample is settled after start of conduction. A voltage detecting circuit 16 detects the voltage variation sequentially and a bias voltage control circuit 17 controls the bias voltage to be applied to the sample 1 so that the voltage fluctuation is compensated for thus correcting the output voltage. This constitution provides a clear image at all times while holding a probe 2 at a fixed height.

IPC: H04Q9/06
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a lighting system capable of performing address setting of luminaire without applying a load at the time of manufacture. SOLUTION: An instruction for address setting is given to set to an address setting mode and an address setting start signal is sent to all luminaires through a communication part 3a by an operation part 3d of a centralized monitoring panel 3. A control part 3b of the centralized monitoring panel 3 gives an instruction to fix a signal voltage level of a transmission wire 1 at a fixed level to the communication part 3a. Next, a control part 2e of the luminaire 2 receiving the address setting start signal operates a constant current load 2b to consume a fixed current due to a voltage between a pair of transmission wires 1 and 1. At this time, voltages of signals on the transmission wire 1 in each luminaire 2 differ due to the effect of impedance component of transmission wire 1 itself and a difference in connection positions of the transmission wires 1. Lastly, each luminaire 2 detects a signal voltage between the transmission wires 1 and 1 and stores the information as an address value in a memory part 2d.
