Title: Semiconductor integrated device
Inventor: MOTOYOSHI KANAME
IPC: H03F3/193
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To compensate the dispersion of the characteristics of the drain current or the like of an FET for control resulting from a manufacture process by simple constitution. SOLUTION: To the gate of the FET 1 for high frequency amplification, a potential obtained by subtracting the portion of a voltage drop generated in a first resistor 22 by the drain current IDS2 of the FET 21 for bias from the potential GND of a first potential applying part 2a is applied. When the pinch off voltage of the FET 1 is shifted from a design value, the pinch off voltage of the FET 21 is also shifted similarly to it and the gate bias of the FET 1 is changed corresponding to it as well. Thus, the dispersion of the drain current IDS1 of the FET 1 due to the manufacture process is compensated by a gate bias circuit 20. Also, since the gate bias circuit 20 is provided with just two pieces of resistors, constitution is simple and a resistance value for obtaining a large compensation effect is easily set.

Filed: 1994-11-29
Abstract: PURPOSE: To obtain a connection surface which smoothly connects with a peripheral curved surface by dividing the connection surface into three areas, and generating curved surfaces in the areas by using information on existent peripheral curved surfaces and then connecting the three curved surfaces. CONSTITUTION: Plural constitution points are set on outlines L1 and L2 according to the curvatures, etc., of outlines L1 and L2. Then, the connection surface C where the constitution points are set is divided into three areas B1 (2nd area), B2 (1st area), and B3 (3rd area). After a curved surface in the center area B1 (Bi=B1) with i=1, curved surfaces in the areas B2 and B3 (Bi=B2, B3) are generated by using curved surface information on the area B1. In this case, the difference between the shape of an outline g4 and the shape of an outline g6 is absorbed by outlines g7 and g8 constituting the center area B1 to obtain the connection surface C which smoothly connects the fillet surfaces F1* and F3*.

IPC: F01L1/04
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing process number, and prevent an increase in a cost by using grooves arranged in an inside diameter of an installing part as lubrication of a cam driving gear and a lubricating oil passage between cam tappets. SOLUTION: A camshaft 1 has a hollow shaft 2, a partially expansible carbon steel material is used, and a sub-gear 6 and a cam lobe 20 for slidably contacting with a main gear 4 and a journal 22 are installed in a prescribed position.

Therefore, the toner concentration in the developer is prevented from excessively increasing, which occurs because the toner 5 passes between the roller 1 and the means 2 and leaks into the developer, and the supply quantity of toner is made constant. Even in the case of using the toner whose grain size is <=10mum, the toner is prevented from leaking into the developer and the toner is stably supplied so as to make the toner concentration constant.
