Title: Vertical trench gate type mosfet with high cell density
Inventor: WILLIAMS RICHARD K
IPC: H01L29/78
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce ON resistance of a power MOSFET by limiting a region for forming a body contact, and using a diode cell, thereby decreasing the width of the MOSFET. SOLUTION: In the MOSFET 70, two MOSFET cells 72 are provided for a plurality of diode cells 74. Gates of the MOSFET 70 are represented by 76A to 76D. The cells 74 are partly sandwiched between regions of a gate part 76C and a gate part 76D, and additional MOSFET cells 18 are formed so as to limit a region for similarly forming a body contact between the cells 74. Thus, the trench gate type power MOSFET having a cell density of 178 M cell/square inch can be manufactured, and an ON resistance value can be reduced.

Abstract: PURPOSE:To secure an assured supervisory for the double unit state to one piece of the transmission line through a simple circuit constitution by detecting the state signal sent from the unit side at the supervisory side and via the polarity switching of the common power bus bar. CONSTITUTION:Supervised stations A and B are connected together via a piece of transmission line L plus common bus bars P1 and N1. At station A state signal transmission circuit 1 transmits both the forward and backward rotation state signals of the blower, along with installation of the circuit in which resistance R2 and contact S2 for the backward rotation are connected in parallel to the serial circuit of resistance R1 and state signal contact S1 which operates at the forward rotation time. While the circuit, in which contact S4 operating in response to the action of the over current detector is connected in parallel to the serial circuit of resistance R2 and fault contact S3 operating at the critical point of the allowance temperatures, is provided to fault signal transmission circuit 2 for transmission of both the temperature increase and overcurrent trip signals of the unit. Furthermore, state signl detector 3, fault detector 4, and change-over switch 5 containing contacts 5a1 and 5b1 plus 5a2 and 5b2 are provided respectively at station B. Thus the detection is possible assuredly for the state signal of the double units via one piece of the transmission line and through a simple constitution.

Title: Preparation of electrochromic element
Inventor: ISHIWATARI KAZUYA
IPC: G02F1/1524
Filed: 1983-08-18
Abstract: PURPOSE:To improve appearance of a pattern by laminating an electrochromic (EC) layer on the first electrode, and bringing an O2 atm. excited by glow discharge into contact with the parts of said EC layer not to be used as the EC layer to erase the EC function. CONSTITUTION:An EC layer 3 is laminated on the first electrode 2 formed on a base plate 1, and then, an atm. of O2 excited by glow discharge, such as ion plating, is brought into contact with the parts of the EC layer 3 not to be used as it to erase the EC function and form a pattern. An insulating layer 4 is formed on the layer 3, e.g., by vacuum evaporation, and further, the second electrode layer 5 is formed on this layer 4. Since the EC layer itself is divided into the parts having the EC function and the parts having no EC function by this treatment, the layer 3 has no or very little level difference. As a result, the obtained EC element has no relieved pattern and good appearance.
