Title: Heater device
Inventor: OSHIO SEIJI
IPC: F24D13/02
Filed: 1990-07-02
Abstract: PURPOSE:To cause a displaying state in a remote controller to be coincided with a state of a main body controller by a method wherein a wireless bi-directional communication is carried out between the remote controller and the main body controller. CONSTITUTION:When a temperature setting means 17 of a remote controller 11 is operated, a temperature signal is transmitted from a remote controller transmitting means 20. When a main body receiving means 12 of a main body controller 9 receives a signal, a temperature setting signal is sent to a controlling means 15. The controlling means 15 controls a heating means 14 to adjust temperature. Concurrently, the main body receiving means 12 sends a signal to a main body transmitting means 16. The main body transmitting means 16 transmits a completion signal of receiving a remote control signal in which a received temperature setting signal and a receiving completion signal are combined to each other. When the remote controller receiving means 21 receives the receiving completion signal, a state discriminating means 18 compares a transmitted temperature setting signal with a set temperature sent back with the receiving completion signal. If they are coincided to each other, a transmission completion displaying signal is sent to a displaying means 19. When they are not coincided to each other, a transmission failure displaying signal is sent to the displaying means 19 and concurrently it sends a signal to an abnormal state sensing means 24 and then an abnormal transmission informing means 24 informs a user of a transmission failure.

Filed: 1985-08-09
Abstract: PURPOSE:To improve operability by giving the 1st original carry-in inlet for conveying an original to platen glass and the 2nd original carry-in inlet which is positioned in the vicinity of a coordinate position detection position and conveys the original subjected to a coordinate input to the platen glass.

Moreover the work for turning the original upside down and moving it to an inlet tray 1 is reduced. Simultaneously such a risk can be eliminated that through moving the original, the original is mistakingly placed by misunderstanding right and left directions at your side and the reference side of the recess, which results in a useless copying.

Title: Ion beam device
Inventor: KASAHARA HARUO
IPC: H01J37/04
Filed: 1987-07-14
Abstract: PURPOSE:To prevent breakdown through a gas by arranging an orifice in an active gas supply pipe so that the pressure in the pipe is increased and the dielectric strength of the gas is increased. CONSTITUTION:An active gas from a gas source 16, after its flow rate is adjusted with a valve 17, is supplied through a pipe 18 onto the surface of a target 10. Since an orifice is formed at the tip 18c of the pipe 18, the gas is blown out through the orifice. As a result, while the pressure of the gas on the surface of the target 10 is made to about 10<-2> Torr which is suitable for etching, the pressure of the gas within the pipe 18 becomes a relatively high value of about 1 atmospheric pressure. The dielectric strength of the gas at the pressure of about 1 atmospheric pressure is high. In the case of activated chloride gas for example, the dielectric strength is 4.65kV/mm at that gas pressure and keeps insulation sufficiently. In this way, breakdown through the gas in the pipe cannot occur.
