Title: Photo detector and its manufacture
Inventor: IDE YUICHI
IPC: H01L21/338
Filed: 1985-05-24
Abstract: PURPOSE:To make high speed response possible in the leading edge and the trailing edge of a signal current, by constituting the structure so as to separately take up the electron current and the positive hole current generated by light incidence to the external circuit. CONSTITUTION:The semiconductor region 23 composed of P-type positive hole drawing up layer 22, N-type block layer 231, and photo absorbing layer 230, the spacer layer 24 to produce the undoped two-dimensional electron gas and the N-type electric charge absorbing layer 25 are formed in order on the semi- insulative semiconductor substrate 21. With respect to the electrode, the source electrode 28, the drain electrode 27, the gate electrode 26 and the positive hole drawing up electrode 29 are formed. The electron-positive hole pair is generated in the layer 230 by the incidence of light into this photo detector. In a very short period of time, the electron of the pair is taken out as the signal between the electrodes 28 and 29. On the other hand, in the structure provided with the layer 22, the positive hole can be taken out to the electrode 29 as the posi tive hole current where the inverse bias is impressed through the electrodes 26 and 29. Thus, the slow component can be eliminated and the high speed response can be obtained.

Title: Low speed rotation detector
Inventor: ONO NAOYA
IPC: G01P13/00
Filed: 1978-09-14
Abstract: PURPOSE: To detect a malfunction at a low speed rotation from the positional relationship between the two shafts which are operative to receive the input rotation and the braking force and which are connected by a spring.  
     CONSTITUTION: An input shaft 1 having a gear at its one end is made to have at its other end a disc 3 which is equipped with a detecting lead switch 12. A braking 5, which is arranged in alignment with the shaft 1, is equipped at its one end with a disc 4 having a permanent magnet 13 and at its other end a braking disc 6 to be dipped in a viscous fluid 8. The discs 3 and 4 are connected by means of a spring 10. With this construction, under the stationary condition, the magnet 13 and the switch 12 are separated from the positional relationship between the discs 3 and 4. When the input shaft 1 rotates, the disc 4 follows the rotation of the disc 3, and the magnet 13 approaches the switch 12 so that the switch 12 is actuated to detect the rotation. When the rotation is stopped, the magnet 13 leaves the switch 12 so that the switch 12 is turned off. Thus, it is possible to detect a malfunction at a low speed rotation.

Abstract: PROBLEM TO BE SOLVED: To prevent the distorted deployment of an air bag by forming recessed grooves along the axial direction on the inner face of an outer tube, and forming gas discharge holes in the recessed grooves. SOLUTION: Recessed grooves 16 are formed in the axial direction on the inner face of an outer tube 5, many gas discharge holes 5a are formed in the recessed grooves 16 to form gas hole lines r1, r2, and the inner faces of the recessed grooves 16 are blocked by a tape-like burst plate 7.

Abstract: PURPOSE:To form cracked glass products having improved quality (appearance and resistance to hot water, etc.) with ease, by coating molded glass products at a high temperature with a powder coating material consising essentially of a specific low-melting glass powder, and baking the coated powder coating material. CONSTITUTION:A powder coating material consisting essentially of a low-melting glass powder (preferably <=550 deg.C softening temperature and grain size: the coated film thickness of the powder coating material or less), satisfying the relation expressed by the formula (alpha1 is the thermal expansion coefficient of the low-melting glass; alpha2 is the thermal expansion coefficient of the body glass), and having a higher thermal expansion coefficient than glass products is used. The low-melting glass powder alone may be used. The above-mentioned powder coating material is electrostatically applied to a molded glass product at a high temperature (about 300-700 deg.C) just after molding the body glass, and baked to prepare the aimed cracked glass product, e.g. glass globe or bottle. The simultaneous baking and annealing may provide the further rationalization of the process in the above-mentioned method.

Abstract: PROBLEM TO BE SOLVED: To improve the thermal efficiency, and to prevent a burner port from being clogged with the overflowed soup, or the lifting from occurring by providing a main burner port group on a outer circumferential wall of a burner body, and inclining the axis of each main burner port over the prescribed angle. SOLUTION: In a horizontal ring-shaped burner in which the primary air ratio is increased up to 60-90% of the ideal mixture ratio, a burner body 1 is provided with a main burner port group 2, and the axis of each main burner port 2 is inclined by >=45 deg. relative to the horizontal plane.

By colliding the flame against the pan bottom, the high- temperature exhaust gas is brought into direct contact with the pan bottom to improve the thermal efficiency.  A flange-shaped part 8 projected in the horizontal direction of a lid plate 6 is expanded in a path of the gas ejecting from each main burner port 2 to prevent ingress of the overflowed soup into the burner port 2.
