Abstract: PURPOSE: To obtain a device that can be mounted and removed easily and can retain airtightness, without occupying space for connection by mutually connecting walls made of an insulation material via a peripheral edge airtight packing and with a space filled with dry air. CONSTITUTION: Rooms 1 and 2 are connected mutually and electrically from one to the other, via a contact that passes through walls 6 and 6'. Pairs of contacts 3, 3' and 4, 4' are connected to each other via an electrical connector 9. Also, the contacts 3, 4, 3', and 4' pass through the walls 6 and 6' that demarcate the rooms 1 and 2 and the walls 6 and 6' are made of an insulation material.

Title: Manufacture for receiving tubes
Inventor: SUZUKI ARINOBU
IPC: H01J29/88
Filed: 1978-02-15
Abstract: PURPOSE: To increase the quality as receiving tubes and to simplify the manufacturing process, by applying the vacuum evaporation method to receiving tubes.  
     CONSTITUTION: The film for reflection prevention is formed as the evaporation film 8 inside the funnel 1 and a part of neck 2, and as the evaporation film 9 inside the supporter 4. Very excellent black film can be formed by evaporating the metal such as gold, platinum, and aluminum under low vacuum around 10 -2  Torr. inside the glass package and the inner part causing photo reflection such as metal frame. Accordingly, since black reflection preventive film is formed inside the receiving tubes, the excellent film having almost no gas discharge after formation can be made, allowing to keep vacuum, increase the quality such as contrast, and simplify the process.

Title: Applicator for spin coating
Inventor: KAKINUMA KEIJI
IPC: G03F7/16
Filed: 1988-01-29
Abstract: PURPOSE:To prevent a splash of scattered coating material from being stuck on a member to be coated by providing a nozzle for application to a supporting turntable which is rotated while supporting the member to be coated thereon and furthermore providing a plurality of fins on a concentric circle around the supporting turntable at nearly equiintervals to the nearly radiate directions from the center of this turntable. CONSTITUTION:While coating for a protective film dropped through a nozzle 10 for application allows to be transferred to the peripheral edge direction with centrifugal force caused by high-speed rotation of a compact disk 5, a paint film having uniform thickness of about 5-10mu is formed on this disk 5. At a time for this formation, excess coating is scattered from the outer peripheral edges of the disk 5 by centrifugal force but allowed to collide against the fins 7 which are provided nearly radiately from the center of a housing 4 to the vertical direction and scattered toward the outside directions of the fins 7. Therefore the coating droplets 5a directed to the direction of the compact dick 5 are made extremely little. Even if the coating droplets 5a are rebounded to the direction returned to the disk 5, these are allowed to collide against the adjacent fins 7 and do not return to the disk 5 and not stuck thereon.

IPC: H01L23/50
Filed: 1979-02-17
Abstract: PURPOSE: To seal the gap between the base surface and the lead surface with a part of the molten resin at the protruberance by a method wherein a protruberance is provided at a side of the joined surface of a thermoplastic resin plate bodies, which are joined together in the manner so that the lead surface does not contact with the base surface whereon a protruberance is provided.  
     CONSTITUTION: Lead frame 5 fitted with a semiconductor is sandwiched by thermoplastic plates 13, 13' having respectively depresions 17, 17'. Before the plates are joined at least one of them is preheated. The plate are joined by heating and under pressure by using tool 18. Depressions 20, 20' are provided on base surfaces 19, 19'. Molten resin flows into gap 16 of frame 5. Further, it flows into gap 22 between base surfaces 19, 19' and lead surface 21, and further to burrs, and thereby tight sealing is done. Since lead surface 21 is jointed with base surface 19 having a depression in the condition that they are not in contact, airtight sealing is done even if the base surfaces of depressions 20, 20' are not flat.

Title: Gate turn-off thyristor
Inventor: SATO YUKIMASA
IPC: H01L29/10
Filed: 1986-01-31
Abstract: PURPOSE:To improve the breaking resistance of a gate turn-OFF thyristor by forming a main current path in a low resistance layer in many pores, and setting the interval of the adjacent pores to carrier diffusion length or shorter in an anode/base layer. CONSTITUTION:A P-type cathode/base layer 2, a P-type low resistance layer 3 and a P-type semiconductor layer 4 are sequentially formed on an N-type semiconductor wafer 1. Many pores 100 are arranged radially in multiple-ring state in the layer 3. A current of ON state flows laterally radially in an N-type anode/base layer 6. Since the interval (b) of the adjacent pores 100 is set to carrier diffusion length of shorter in the layer 6, the layer 6 directly under the layer 3 is conducted. Thus, the ON voltage does not rise. A gate turn-off resistance can be reduced by decreasing the size (a) of the pore 100.

Abstract: PURPOSE:To facilitate the layout of a bit line within a pitch, and to reduce an area by connecting and cutting off two adjoining bit lines to/from a data bus through a switching means whose input is the signal of a column line. CONSTITUTION:The information of a memory cell selected by a line decoder appears in sense amplifiers 30m to 30m+3, and the cell information is read out. At that time, when the column line CLn is turned into a selective state and the column line CLn+1 is turned into a non-selective state by a row decoder, the N-channel MOS transistors (NMOS) 40m, the inverse of 40m, 40m+1, and the inverse of 40m+1 become conductive, and the amplifiers 30m, 30m+1 become conductive to data bus pairs DB0, the inverse of DB0, DB1, and the inverse of DB1 respectively through common contacts Pm/m+2, the inverse of Pm/m+2, and data can be transmitted from the sense amplifier to the bus pair. On the contrary, at the time of data writing operation, the data can be transferred from the data bus pair to the sense amplifier through the common contact and the NMOS. Thus, the adjoining bit lines can be connected to the data bus by the same node, and the layout area is reduced, and densification can be realized.
