Title: Photoelectron emission surface and electronic tube using the photoelectron emission surface
Inventor: ARAGAKI MINORU
IPC: H01J31/50
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a higher sensitive photoelectric emission surface having an active layer dissolving crystal defects and an electronic tube having the photoelectric emission surface. SOLUTION: On the photoelectron emission surface, an epitaxial layer formed by laminating a window layer 31 consisting of (Aly Ga1-y )x 'In1-x P and an active layer 32 consisting of Gax In1-x P in that order is closely provided through an antireflection film 20 on a glass face plate 10. A very thin surface layer 33 consisting of Cs2 O and an electrode 40 consisting of Cr and formed on the upper surface of the active layer 32 at the central part and the peripheral edge part. Crystal defects are dissolved in the active layer 32 in a range of an atomic composition ratio x of 0<x<=0.75, almost equal to the atomic composition ratio X' of the window layer, lengthening the diffusion length of a photoelectron generated by directing light to be detected, an object for detection, in the active layer 32.  Thus, the photoelectric emission surface comes to higher sensitivity rather than conventional sensitivity. An electronic tube using the photoelectric emission surface detects weaker light rather than conventional light.

Title: Production device for semiconductor
Inventor: KOSHIDA HARUTAKA
IPC: H01L21/68
Filed: 1987-01-30
Abstract: PURPOSE:To prevent the detection of the orientation flat of a wafer at the time of pre-alignment by detecting the orientation flat of the wafer by the attitude of a pin for pre-alignment. CONSTITUTION:Rectangular pins 3 for pre-alignment turned centering around shafts 3a while being brought into contact with the orienta tion flat 2 of a wafer 1 and following the direction of the orientation flat are provided. A reflecting mirror 5 is set up to the pin 3. When the direction of the flat 2 is displaceed, the pins 3 are rotated, following the change of the direction of the flat 2. Consequently, beams 7 emitted from a light source 4 are reflected in the direction displaced from a photodetector 6 by the reflecting mirror 5, and are not projected to the photodetector 6. The flat 2 is not positioned correctly at that time, and is compensated at a precise position through pre-alignment. Accordingly, the erroneous detection of the flat 2 is obviated.

Title: Ignition control device for internal combustion engine
Inventor: IWATA TOSHIO
IPC: F02P3/045
Filed: 1986-01-30
Abstract: PURPOSE:To improve transition responsiveness of an energizing timing control and prevent flameout, by changing a feedback control calculation constant of an ignition coil energizing timing when an engine is accelerated abruptly. CONSTITUTION:A current detection circuit 20 outputs a current detection signal to a CE logic circuit 21 while a primary current to an ignition coil reaches a prescribed value. Since a feedback control is effected based on the current detection signal, the period during which the primary current reaches a prescribed value can be controlled to a prescribed ratio of an ignition cycle. When the current detection signal is not output, a logic circuit 10 changes a constant for a feedback control operation of a second up down counter 12 in the next ignition cycle so that an energizing timing in an abrupt acceleration is compensated and a drop of a shut-off current is prevented. Therefore, a sufficient shut-off current is maintained for preventing flame out.
