Title: Apparatus for steam drying and cleaning
Inventor: KUSUHARA MASAKI
IPC: H01L21/304
Filed: 1985-04-15
Abstract: PURPOSE:To keep isopropyl alcohol (IPA) or the like from vaporization by pouring water on a box housing a heater and a container containing IPA. CONSTITUTION:When a current is applied to a heater in an aluminum box 1, IPA 2 is vaporized. When a wafer 5 which is cleaned by deionized water beforehand is carried into the IPA 2 vapor by a movable hanger 7, the wafer 5 is dried and cleaned. If power failure caused by, for instance, a thundetbolt occurs during such drying and cleaning process, a flow of cooling water through a bellow tube is stopped. IPA 2 is heated by residual heat from the aluminum box 1 and the outside atmosphere of a quartz container 3 is filled with the vapor of IPA 2 so that a hazardous condition, under which the atmosphere may reach the lower explosion limit, is created. A cock 11 is opened manually to discharge water stored in a tank 9 onto the aluminum box 1 to cool it down quickly and at the same time to discharge the water into the quartz container 3 so that IPA is diluted and kept from vaporization.

Title: Telephone circuit switching device
Inventor: NITSUTOU KOUICHIROU
IPC: H04M11/00
Filed: 1981-05-26
Abstract: PURPOSE:To obtain a telephone circuit switching device which can assuredly obtain the hook information with a small size, a low cost and high voltage resistance, by putting a photocoupler in series into a telephone circuit and using the output of the telephone circuit as the hook information. CONSTITUTION:When a telephone set 3 is hooked off, a current flows to a photocoupler 53A or 53B from a current supply source E of a telephone exchange 1 via a telephone circuit 2 and in accordance with the polarity. Thus the inputs of the Schmitt triggers 53C and 53D receive the division of voltage through the resitances R and R1-R4. The output singals of the triggers are opposite to each other. As a result, the output signal of a gate 53E is set at H level to show the off-hook state. When the telephone set 3 is hooked on, no current flows to both photocouplers 53A and 53B. Thus the gate output is set at L level to show the off-hook state. Furthermore the on-hook state is assuredly obtained through the time constant circuits R and C although the call signal is transmitted.
