Patent number: 8540917Abstract: An insert molding method includes holding a plurality of insert members in a molding die to be separated from one another, and subsequently filling a resin into the molding die to fill a gap between the insert members and a periphery thereof with the resin to form an insert molded product such that the insert members are separated at a preset interval from one another. The molding die includes a space-maintaining projection for maintaining a separation interval between the insert members at the preset interval or more, the projection being formed on an inner wall surface of the molding die opposite to a longitudinal end of the insert members, and a gate for filling the resin therethrough into the molding die, the gate being formed on an inner wall surface of the molding die opposite to a side of the insert members in a width direction thereof.Type: GrantFiled: December 1, 2010Date of Patent: September 24, 2013Assignee: Hitachi Cable, Ltd.Inventors: Satoshi Yamamoto, Akihiro Tanba, Masafumi Kaga

Patent number: 8395474Abstract: A position sensor cord includes a hollow insulator formed of a restorable rubber or a restorable plastic, and two linear resistive members. Each of the two linear resistive members includes a linear insulator and a conductive layer provided around a circumference of the linear insulator. The conductive layer is formed of a conductive rubber or a conductive plastic. The two linear resistive members are arranged in no electrical contact with each other and along an inner surface of the hollow insulator. One of the two linear resistive members may be replaced with one linear conductive member.Type: GrantFiled: January 12, 2012Date of Patent: March 12, 2013Assignee: Hitachi Cable, Ltd.Inventors: Akihiro Tanba, Takashi Aoyama

Patent number: 8299807Abstract: A foreign objection detection sensor has a lengthy sensor part having a sensor electrode having a first sensor electrode which detects a proximity of a foreign object and a second sensor electrode which detects a contact of the foreign object, a sensor terminal part provided at one end of the sensor part, a leading wire pulled out from the sensor terminal part, the leading wire being electrically connected to the sensor electrode at the sensor terminal part to provide a proximity detecting function for detecting the proximity of the foreign object to the sensor part and a contact detecting function for detecting the contact of the foreign object to the sensor part. The sensor terminal part has a support member which supports a detection circuit unit electrically connected to the sensor electrode to carry out the proximity detecting function and the contact detecting function together with the sensor electrode. The detection circuit unit is disposed in the support member.Type: GrantFiled: February 24, 2010Date of Patent: October 30, 2012Assignees: ASMO Co., Ltd., Hitachi Cable, Ltd.Inventors: Ryousuke Sakamaki, Akihiro Tanba, Takashi Aoyama, Akio Hattori, Teruji Sato, Tatsuya Ohtaka

Patent number: 5045904Abstract: A small and reliable semiconductor device is provided in a substrate which has an isolation trench and a capacitor trench. The isolation trench isolates a bipolar transistor from other semiconductor devices, and the capacitor trench provides capacitance to a memory cell which is formed in the substrate. The interior of the device isolation trench is kept in a floating state with respect to the surrounding semiconductor regions by forming an insulating film over the inner surface of the trench. In the capacitor trench, insulating layers and resilient conductive layers are formed alternately to form capacitance between the opposing conductive layers.Type: GrantFiled: December 20, 1988Date of Patent: September 3, 1991Inventors: Yutaka Kobayashi, Akihiro Tanba, Ryoichi Hori, Kyoichiro Asayama, Seigoh Yukutake, Hiroyuki Miyazawa, Kazumasa Yanagisawa, Goro Kitsukawa
