Next, an a-Si layer 14 and poly-Ge capping seed layer 16 are vapor-deposited by a low pressure chemical vapor deposition method. Next, a film of the a-Si layer 14 having the poly-Ge capping seed layer 16 is annealed for 2 seconds at 570 deg.C and crystallized. And a grain boundary 18 and a nucleus formation site 20 of the capping seed layer 16 are reproduced to crystallized silicon 14 as a grain boundary 22. Next, the capping seed layer 16 is removed by an etching solution of H2 O:H2 O2 :NH4 OH:=5:1:1. By doing this, the throughput of treatment can be improved.

Title: Blade for electrophotographic device
Inventor: SAKO YASUHIRO
IPC: C08L75/04
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a blade for an electrophotographic device capable of controlling the edge precision of an abutting part and a coefficient of friction over a long period by coating the abutting part of a blade member with a specific resin. SOLUTION: The blade member 1 is made of a polyurethane elastomer and at least the abutting part of the member 1 is coated with a resin 3 having a coating film hardness of pencil hardness of B to 6H. The abutting part of the blade member 1 is a part abutting against the other member, for instance, a photoreceptor such as a photoreceptive drum and a photoreceptive belt, a roll such as a developing roll and a belt such as a transfer belt. Thus, the coating film hardness of the resin 3 is limited to reduce the coefficient of friction, so that it is unnecessary to use fluororesin grains damaging the edge precision, silicone having low coating adhesion, etc., and the resin can be selected in such a manner that great importance is placed on the adhesion of a base material to the polyurethane elastomer and the edge precision.  Further, friction is easily made low and the edge precision can be kept excellent.

Title: Thermistor with positive temperature coefficient
Inventor: YAMADA YOSHIHIRO
IPC: H01C7/02
Filed: 1987-12-10
Abstract: PURPOSE:To shut out humidity and gas from a case by combining electrically and mechanically contact terminals inside the case and connecting terminals outside the case by conductive rivets which pass through each case component. CONSTITUTION:For preparation, contact terminals 5 and 6 are set up inside each of the components 1a and 1b of a two-divided case respectively and connecting terminals 7 and 8 are set up outside 1a and 1b. Then, contact terminals 5 and 6 are combined by caulking electrically and mechanically with connecting terminals 7 and 8 respectively by conductive rivets 14 and 15. Nextly, the case components 1a and 1b are put face to face, between which a positive temperature coefficient thermistor element 2 is put to combine 1a and 1b. Due to caulking by the rivets 14 and 15, no space is allowed to be caused when taking the terminals out of the case, resulting in sealing up the positive temperature coefficient thermistor 2 inside the case. This method allows no humidity nor gas to come in and thereby avoids deterioration of the element.

Title: Image formation device
Inventor: TAKEMURA OSAMU
IPC: B41J2/385
Filed: 1990-11-19
Abstract: PURPOSE:To improve passing efficiency of toner and uniformize the amount of dropping of toner by providing in a toner control means an ultrasonic vibration generating means for imparting ultrasonic vibration to one side of the toner control means and an elastic member attached on the other side between a supporting member and said control means. CONSTITUTION:Since vibrations having constant amplitude are applied to an upper mesh-like electrode 23 by means of an ultrasonic vibration generating means 30, blocks of toner fed onto the electrode 23 are crushed and passed through an upper mesh-like electrode 25. And an elastic member 31 is fixed to an end of a toner control means 20 opposite to a point where the means 30 is positioned. Since vibrations transferred from the means 30 toward the member 31 over the means 20 are absorbed at the position of the member 31, no reflected wave is generated in a direction toward the position of the means 31. As a result, ultrasonic vibrations are not concentrated in a specific area, so that the amount of dropping of toner can be uniformized.
