Title: Semiconductor device
Inventor: NAGAHAMA KOUKI
IPC: H01L31/10
Filed: 1982-07-07
Abstract: PURPOSE:To obtain a high quality N type crystal layer, without the effects of delicate change in heat treating conditions and a minute amount of impurities, by thermally diffusing In in Hg1-xCdxTe (0<=x<=1) and providing an N layer. CONSTITUTION:Hg and Cd, whose vapor pressure is high, are evaporated during the crystal growing from Hg1-xCdxTe and defects are liable to occur. The thin film crystal of the Hg1-xCdxTe incurs serious damage owing to said defects. Vacant holes, from which Hg and Cd are evacuated, become acceptors, and a P type semiconductor is obtained in general. Heat treatment of said P type crystal is performed under the vapor pressure of the Hg and Cd, and the P type crystal can be changed into an P or N type crystal, whose carrier concentration is further lower. Even in this case, however, the crystal is liable to receive the effects of heat treating conditions and impurities, and a high quality film is head to obtain. When In is thermally diffused on the entire or partial surface of an N or P type Hg1-xCdxTe layer, which has high resistivity and low mobility, a high quality N type crystal, which has low resistivity and high mobility, can be readily obtained, and various functional elements can be constituted.

Title: Steering wheel
Inventor: NAKAYAMA TETSUYA
IPC: B62D1/04
Filed: 1985-06-01
Abstract: PURPOSE:To prevent the occurrence of lost motion or the like based on backlash, etc., between gears, by attaching an elastic member for energizing a planetary gear in a tangential direction in common with each pitch circle of the planetary gear and a sun gear, to a boss plate of a planetary gear mechanism. CONSTITUTION:When a ring 13 is turned round and steering operation is performed, two planetary gears 5a and 5b revolves with rotation of a boss plate 11 as rotating around each of sun gears 3a and 3b at both column and pad sides. However, since the sun gear 3b at the column side is locked to a column 7, it will not rotate, therefore the sun gear 3a at the pad side also will not rotate so that it comes to nonrotation with the column 7. Accordingly, a pad part 1 being tightly attached to the sun gear 3a at the pad side also comes to nonrotation. In addition, since each of these planetary gears 5a and 5b is engaged with these sun gears in a state of being energized, one tooth 23 of each of these planetary gears 5a and 5b come into contact with both sides 26a and 26b of each tooth space 24 of these sun gears 3a and 3b.

Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To reduce residual stress remained in metallic strip to a desired level by means of passing the metallic strip for electronic member of a lead frame and the like through a roller leveler, and controlling a bend radius and tension during passage therein correlatively by parameters. SOLUTION: Designating the tension in the roller leveler of the lead frame and the like during passage therethrough as σT, parameter α (α=2πσY/(ET)) and parameter designated as β (β=σr/σY) are correlatively controlled. As the case may be, the parameter β can be controlled by making β depending on α. E in the above is Young's ratio of metallic strip. ρ is a bend radius, T is the thickness of metallic strip. And a tension σT and the bend radius ρ of the roller leveler of the metallic strip are the tension and the bend radius at the entrance side of the roller leveler.  Practical procedure in the correlative control is not limited, but the most simple way is either to control tension σr by preliminary set of the bend radius ρ or to control the bend radius ρ by preliminary set of the tension σT.

Title: Telephone system
Inventor: FUJIMOTO KIYOJI
IPC: H04Q3/58
Filed: 1988-05-17
Abstract: PURPOSE:To decide the difference of motion time points and to set one mode out of three types of the modes by providing two hook switches which can operate the motion time points so as to be differentiated. CONSTITUTION:When the mode which does not catch any of a trunk line or an extention is set, and a user approximately horizontally lifts a handset 10, a detecting circuit 7 detects the change of the connecting condition of hook switches 5 and 6, and inputs it to a deciding circuit 8. The deciding circuit 8 decides that the changed time points are the same in an allowable error range for the hook switches 5 and 6, and outputs a signal P0. When the user tries to catch the trunk line, and he lifts the handset 10 from a right side, the deciding circuit 8 decides that the condition change of the hook switch 5 is earlier, and outputs a signal P1. When the user tries to catch the extention, and he lifts the handset 10 from a left side, the circuit 8 decides that the change of the hook switch 6 is earlier, and outputs a signal P2. Thus, the one desired mode out of three modes can be set.
