Inventor: IDE TAKASHI
IPC: C03C25/12
Filed: 1986-02-27
Abstract: PURPOSE:To reflect only ultraviolet rays having an available wavelength region and to efficiently cure resins by providing the following reflector for ultraviolet rays to a device for irradiating ultraviolet rays which reflects light in the range of 300-450nm wavelength and absorbs or transmits light having the wavelength other than the above-mentioned range. CONSTITUTION:An interference film is formed by vapor-depositing a nonmetallic multilayered thin film on the surface of a reflector 3 made of glass but it is formed so that only rays of light having 300-450nm wavelength among ultraviolet rays emitted from an ultraviolet lamp 2 are reflected and rays of light having the other wavelength region are transmitted by controlling a substance to be vapor-deposited, the film thickness of vapor deposition, and a number of a layer of the film. Heat can be discharged to the outside by cooling a housing 4 with air-cooling and the heating of an optical fiber 1 coated with UV region can be prevented. As a result, even when irradiating rays of light large power on UV resin surrounding the fiber 1, the rays of light having the wavelength other than 300-450nm wavelength are reduced and the curing of UV resin can be favorably performed.

Title: Inverter type x-ray diagnostic equipment
Inventor: TODA HITOSHI
IPC: H05G1/32
Filed: 1989-02-27
Abstract: PURPOSE:To make the title equipment employable in spite of any capacity of an AC power supply by increasing the capacity of a capacitor to such a degree as satisfying a maximum X-ray radiographing condition, and opening and closing a charging switch according to both the upper-limit value and the lower-limit value of charging voltages. CONSTITUTION:When an electromagnetic contactor's contact a in a charging switch 2 is closed, a charge of an alternating current from an insulating transformer 3 is given to a capacitor 5 via a rectifier 4. This capacitor 5 is required to have a capacity enough to satisfy X-ray radiographing conditions. The voltage charged into the capacitor 5 is controlled at a level suited to a set tube voltage by a chopper 7 and then converted into an alternating current which is applied to an X-ray tube 12 via a high- tension transformer 10 and thence via a high-tension rectifier. During X-ray radiation, the switch 2 is opened and all of operating energy required at X-ray radiation are then covered with electric charges given to the capacitor 5. A capacitor charging voltage control circuit 14 opens and closed the switch 2 when a charged voltage detected by a potential divider 13 reaches the upper limit value and the lower-limit value, both of which are predetermined. This makes it possible to employ the title equipment in spite of any capacity of an AC power supply.

Abstract: PURPOSE:To reset easily and automatically a system controller to its original control state in case the control fails with a device during the control of system devices, by reading successively the contents of a storage device which stores the results of the system control and then converting the control command of a device which is controlled in the last time. CONSTITUTION:A control starting command is given to an electric system controller 1 through a control board 5. Then the number of control result devices of a storage device 3 for electric system control result is set at 0. The control commands are given to controlled system devices 6a-6n via a signal transmission line 7 in accordance with an electric system control display. When the control succeeds with each device, the number is increased for the control result devices of the device 3. Then the information of each control result device as well as the control command are successively stored. If the control fails, the contents of the failure are displayed on a display 4. Then the control commands of the same number as the control result devices are inverted based on the information so far stored. Thus the system devices are controlled.

IPC: F16D41/06
Filed: 1983-03-16
Abstract: PURPOSE:To secure a braking effect as well as to aim at improvements in fuel consumption, by constituting a controller in a way of installing a one-way clutch to be connected in time of normal load running and another one-way clutch to be connected at a specified torque value or less in time of reverse load running, in a power transmission system in a parallel manner. CONSTITUTION:In time of normal load running, a driven gear 8 turns to the driving side in relation to a relay shaft 4, while a first one-way clutch O1 comes into a state of being connected, and its power is transmitted to a transmission input shaft 3 from an engine E via those of a shaft driving gear 7, the driven gear 8, the first one-way clutch O1, the relay shaft 4, a driving gear 10 and a driven gear 11. In time of reverse load running, the relay shaft 4 turns to the driving side in relation to the driven gear 8, while another one-way clutch O2 gets connected whereby the first one-way clutch O1 is disconnected, thus an engine brake works for its function. At this time, if large torque is the case, a needle roller 17 slides on each of conical surfaces 14a and 15a, loosening the clutch force. With this constitution, secureness in the engine brake and reduction in fuel consumption are well promoted.
