Title: Optical axis moving mechanism for optical system
Inventor: IDESAWA MASANORI
IPC: G02B6/26
Filed: 1987-07-03
Abstract: PURPOSE:To facilitate the adjusting work of an optical axis of an optical system by inserting a light transmission body in which a light incident surface and a light emitting surface are parallel to each other and which has a uniform refractive index, so that the light incident surface and the light emitting surface become a direction for crossing the optical axis of the optical system, and also, the direction to the optical axis can be changed. CONSTITUTION:The titled mechanism is constituted so that an angle to an optical system optical axis AX1 of a light transmission body PS inserted between an image pickup lens L and an object O can be varied. In case the transmission body is not inclined, a point on the surface of the object O corresponding to an image I formed on a photodetector by the image pickup lens L becomes a more distant point T0 than a point T0V in case the transmission body PS is not inserted, on the extension of the optical axis AX1 of the optical system. When the transmission body PS is inclined by angle theta, the point on the object ) to the image I on the photodetector D becomes TH, and in the end, an equivalent effect to a fact that an effective optical axis between the light transmission body PS and the object O has moved by a distance delta is obtained. In such a way, a work for an axial alignment of the optical system is facilitated.

Title: Semiconductor device and manufacture
Inventor: HIROTA TAKUYA
IPC: H01L27/088
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device with small parasitic capacity and its manufacturing method. SOLUTION: An impurity diffusion region 7 is formed at a joining position, with a semiconductor substrate 1 or a well region 2, under a drain region 6. The impurity region 7 has an impurity density lower than that of the drain region 6 and the semiconductor substrate 1 or each region of the well regions 2. In this case, a MOSFET with a lightly doped drain(LDD) structure is formed, in which the diffusion region 7 is not formed at the side of the drain region 6 in the vicinity of the gate, so that a sidewise distance of the low-density diffusion region 7 from a gate polycide 4 is larger than that of the drain region 6. In this structure, a pn-junction (diffusion) capacity is reduced by about 35% as compared with a conventional MOS transistor with the LDD structure, and high speed in MOS transistor is realized.

IPC: H05B37/02
Filed: 1994-07-19
Abstract: PURPOSE:To provide a dimming device which can carry out turning on and off and dimming a light by simple operation of one operation switch. CONSTITUTION:Based of the operation timing of an operation switch 4d and the data regarding the standard quantity of light, a sequence decoder 8 instructs a counter 72 composing a lighting modulation controlling part 7A to count up or down. The counted value of the counter 72 is D/A-converted into an analog signal by a D/A converter 73, supplied to a light dimming unit 2, and the quantity of the illuminating lamp 3 is controlled so as to be proportional to the counted value. When a first operation is done through an operational switch 4d, the operational switch 4d starts to increase or decrease the quantity of light of the lamp 3 at a prescribed changing speed and when the next operational is done through the switch 4d or when the quantity of the light reached previously set maximum or minimum value, the operational switch 4d stops the alteration of the quantity of the light. In the case the operational switch 4d is operated twice continuously within a prescribed time, the switch carries out previously set control or decreasing control of the quantity of light and on the contrary, when the switch is operated only one time, the switch carries out reverse control.
