Title: Semiconductor device and manufacture thereof
Inventor: ZUN SON RI
IPC: H01L29/78
Filed: 1994-10-14
Abstract: PURPOSE: To obtain a MOSFET structure with a source/drain without any side surface diffusion by burying, to a specific depth, the source/drain consisting of a conductive substance layer into a silicon substrate at both edges of a gate that is formed via a gate insulation film on a silicon substrate. CONSTITUTION: In a MOSFET, a gate electrode 14 is formed on a silicon substrate 11 via a gate insulation film 13, and a conductive substance is embedded into both edge parts of the gate electrode 14 by a specific depth, thus forming a source/drain 19. The source/drain 19 is formed by etching the substrate site of both edges of the gate electrode to a specific depth and embedding a conductive substance into the etched part. Then, an insulation film 17 is formed on the surface of the gate electrode 14, thus preventing the gate electrode 14 and the source/drain 19 from being short-circuited. The source/drain 19 is formed, for example, by n+ polysilicon (when the substrate is p type).

Title: Optical reader
Inventor: HASEGAWA KAZUO
IPC: G06K7/10
Filed: 1987-10-30
Abstract: PURPOSE:To decide a start even when a start margin is short by deciding the start according to the numerical relation between a counted value whose count is started by a counting means and a counted value counted between edges according to the width of an immediately preceding code. CONSTITUTION:According to the numerical relation between the counted value whose count is started by the counting means 6 and the counted value counted between the edges according to the width of the immediately preceding code, the start is decided and if it is improper, a reset signal is applied to a decoding means. Namely, if the counted value according to the improper code is read to the decoding means, it is immediately reset, the counted value is newly reread and the reading probability of information read to the decoding means is high. A decision whether the start is proper or improper is not influenced by scanning speed for reading the code by a detecting means but the decision is executed in a time according to the scanning speed. Thereby, a narrow space as the start margin is satisfactory.

Filed: 1986-11-20
Abstract: PURPOSE:To surely isolate a low stiffness transfer material such as a thin sheet and to prevent the disturbance of an image after isolation by disposing a 1st destaticizing electrode adjacent to the downstream side of a transfer electrifier and a 2nd destaticizing electrode on the more downstream side. CONSTITUTION:The 1st desticizing electrode 4 is disposed in a shield case on the downstream of the transfer electrostatic charger through an insulating material 5a, viewed from the traveling direction of the transfer material, and the 2nd destaticizing electrode 6 away from the 1st one to the downstream side through an insulating material 5b. Since the transfer electrifier 2 discharges positive coronas, a negative DC bias is impressed on the 1st destaticizing electrode, and the 2nd one is grounded. Because of the biased 1st electrode, negative charges given to the transfer part are removed from the transfer material that has finished transfer to some extent, whereby the transfer material such as a thin sheet that is hardly isolated can be smoothly isolated. After the transfer material has passed through the 2nd electrode 6, its remaining charges are removed, then conveyed to a fixing part. Thus no disturbance of an image occurs.

In this bellows pipe 8a, a pipe wall at the side of one end being connected to a fixed part 9 is thicker than other parts and larger in rigidity. Consequently, even if bending displacement is added to this bellows pipe 8a, rigidity in the vicinity of the fixed part increases and it is hard to be deformed and, what is more, generating stress becomes smaller so that stress distribution is equalized as a whole In this connection, when an ambient temperature varies, if the end part plenty of the number of layers is used at the high temperature side, it is very effective.
