IPC: H02K1/06
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To increase the torque of a stepping motor and improve high-speed response.

Title: Bonded of resin member and resin member
Inventor: KARASAWA JUN
IPC: B29K81/00
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To raise the bond strength between a resin member excellent in chemical resistance and another member by modifying the surface of the resin member by a simple apparatus in bonding both the members with an adhesive. SOLUTION: A resin member which is mixed with titanium oxide 2 and molded is firstly irradiated with ultraviolet rays having a long wavelength. Titanium oxide on the surface of the resin member in the operation is excited to generate electrons and holes in the interior. These electrons and holes are reacted with oxygen and water in air to produce an active oxygen seed on the surface of the resin 1. The active oxygen seed acts on the polymer component of the resin 1 to form a polar functional group in these molecules. Polarity on the surface of the resin member is enlarged by these functional groups to improve affinity for an adhesive. The surface of the resin member is modified in the operation to bond the resin to another member with the adhesive.

Abstract: PURPOSE:To contrive quick access time by using a 1/2 Vcc precharge for the RD line having a load made larger. CONSTITUTION:The RD line is connected to a 1/2 Vcc generating circuit 1 and made so as to stabilize at the 1/2 Vcc potential when all sense amplifiers S1-Sn are in nonselection.
