Title: Dice material for sintering furnace
Inventor: MORITA SATOSHI
IPC: C04B35/83
Filed: 1987-10-12
Abstract: PURPOSE: To reinforce both circumferential direction and longitudinal direction by a method wherein a filament winding(FW) laminated layer having a carbon fiber wound in a circumferential direction of a cylinder and a sheet layer having a fabric of carbon fiber coated with resin or one-way prepreg wound with a direction of fiber being directed in a longitudinal direction of the cylinder are overlapped with each other to form a carbon fiber reinforced carbon material with a base material made of the above layers. CONSTITUTION: A carbon fiber 1 is passed in a resin immersion tank 3 while a specified tension is being applied by a tension applying part 2 and after the fiber is immersed with the resin, the fiber is wound around a mandrel 4 to form a reinforcing layer in a circumferential direction, i.e., a FW layer 5. Either a fabric of carbon fiber immersed with resin or one-way prepreg 6 are overlapped on the FW layer 5 and adhered to each other to form a longitudinal reinforcing layer, i.e., a sheet layer. In addition, the carbon fiber is wound in a circumferential direction while the carbon fiber 1 is immersed with the resin to form the FW laminated layer 5. In this way, a base material for a die member reinforced in a circumferential direction and a longitudinal direction is formed by the FW laminated layer 5 and the sheet layer.

Title: Semiconductor memory device
Inventor: KITSUKAWA GORO
IPC: G11C11/409
Filed: 1985-11-15
Abstract: PURPOSE:To reduce the access time of a DRAM to about one third, and the cycle time to about the half by detecting with high sensitivity and at high speed the micro differential signal of a selection string read out at a pair of common data lines by a differential amplifier in which a bipolar transistor is used. CONSTITUTION:By performing a string selection at phiy after a sense amplifier and an active restore circuit are started to operate in a readout time, a current is conducted from one side on load resistors RL1 and RL2 provided at a common data line to a lower side, D or the inverse of D, and the one side of the data line becomes a high potential and the other a low potential. A potential difference is amplified at a bipolar differential amplifier MA, and is sent to a circuit at a succeeding stage. The bipolar differential amplifier, since it has the high sensitivity, can perform a current switching almost completely with the base potential difference of about 0.1V. Therefore, at an early stage when the signal potential of the common data line is changed, the bipolar amplifier can start to be operated.

IPC: H01L23/522
Filed: 1993-09-17
Abstract: PURPOSE:To reduce production cost by shortening a producting process and increase reliability by increasing the barrier effect to a metal plug. CONSTITUTION:Since a TiN layer 25 connecting a P<+> diffusion layer 13 and an N<+> diffusion layer 14, and a TiN layer 34 interposing between an N<+> diffusion layer 24 and a tungsten plug 31 are the same layer, these TiN layers 25, 34 can be formed at the same time. Since the aspect ratio of a contact hole 33 for the TiN layer 34 is small, the step coverage of the TiN layer 34 is excellent. The TiN layer 34 effectively acts as the barrier metal to the tungsten plug 31.

Title: Thermosensitive recorder
Inventor: MIYAZAKI KAZUYOSHI
IPC: B41J11/14
Filed: 1987-10-09
Abstract: PURPOSE:To position a heating resistor at the contact between a platen and the substrate of a recording head to maintain optimal recording conditions by engaging a frame movably with a pair of bearings which hold a platen rotatably in an opening provided in the frame. CONSTITUTION:For printing, a frame 22 is manually turned in the direction of the arrow E. As the frame 22 turns, a bearing 12 advances along a guide 30 of a positioning member 16 against the action of a spring 27 and guided to the right position by positioning edges B and C of the positioning member 16. This constantly provides optimal recording conditions. The positioning edges B and C of the positioning member 16 are oriented substantially at right angles with respect to the substrate 14 of a thermal head 13. Therefore, if there are variations in the deformation of a platen 10 and the force of the spring 27, a heating resistor 15 is located at a point where the platen and the substrate meet. Thus, optimal recording conditions can be constantly obtained.
