Title: Automatic method for detecting improper sealing of container opening edge and its apparatus
Inventor: YASUDA SHIGERU
IPC: B65B57/02
Filed: 1988-01-13
Abstract: PURPOSE:To permit an automatic and uniform checking of a lid on the opening edge of a container for improper sealing, by dropping a weight onto a sealing lid, so that photoelectricity can be shielded intermittently or continuously by the rebounding condition of said weight and rejecting as improper sealing when a continuous light shielding is detected. CONSTITUTION:When a container 1 stops in a predetermined position, a weight 4 is dropped onto a sealing lid 3. At the moment when the weight 4 drops, the photoelecricity from a photoelectric tube 12 which has been detected up to that time by a photoelectricity sensor 13 is shielded by a position detecting shielding plate 11, thereby impeding the detection by the photoelectricity detector 13. In the case of a proper lid sealing, the weight 4 makes a large rebound by its reaction with impact caused by its dropping, thus moving up and down to thereby allow the photoelectricity from the photoelectric tube 12 to be detected by the photoelectricity sensor 13, without being shielded by the position detecting shielding plate 11. In the case of an improper lid sealing, on the other hand, the weight 4 makes less rebound with its reactive force absorbed. Therefore, the position detecting shielding plate 11, although moving slightly up and down, continuously shields the photoelectricity from the photoelectric tube 12 to continuously impede the detection by the photoelectricity sensor 13.

IPC: H01L29/872
Filed: 1995-01-20
Abstract: PURPOSE: To obtain a Schottky barrier diode in which the leak current can be suppressed low upon application of reverse voltage without varying the forward voltage characteristics. CONSTITUTION: A plurality of small diameter Schottky barrier diode structures S, each comprising an anode electrode 2, a cathode electrode 3 and a guard ring 4 formed on the surface layer of a silicon pellet 1, are arranged on one pellet 1. In each structure S, the inner circumferential diameter (y) of the guard ring 4 is set to satisfy a relationship y<=2x, where (x) represents the thickness of a depletion layer 6 spreading at the PN junction between the P-type region of the guard ring 4 and the N-type region of the silicon pellet 1 upon application of reverse voltage. Since the Schottky junction between the silicon pellet 1 and the anode electrode 2 is concealed by the depletion layer 6 upon application of reverse voltage, leak current can be reduced.

IPC: B21D28/14
Filed: 1986-01-16
Abstract: PURPOSE:To perform the punching of good accuracy by enabling the micro movement of the body to be worked which is pressed between a pressing part and die and by giving the resiliency against the punch descending power to an ejector temporarily. CONSTITUTION:The outer peripheral part of the body to be worked is pressed in the space with a die 10 by a pressing part 3 by descending the upper die 2 by placing the body 5 to be worked on the die 10. The projecting part 7 of a punch 4 is abutted to the body 5 to be worked by the descent of the punch 4 to deform the outer peripheral part 14 by pulling it to the inner part somewhat and simultaneously a driving mechanism 12 presses an ejector 11 to the upper part. The punch 4 descends since the descending power of the punch 4 is larger than the pressing force of the driving mechanism, the driving mechanism repulses temporarily and the projection forming is performed by a projection die 7 and recessed die 13 of the ejector 11. The body 5 to be worked deformed slightly is pressed between the lower face excluding the projection die 7 and the upper face excluding the recessed die 13 and the deformation is straightened as well as the outer peripheral face 14 is slightly moved to the outer part. With further descent of the punch 4 the body 5 to be worked is punched inside a pierced hole 9.

Title: Flow control device
Inventor: KATO SEIICHI
IPC: F16K1/52
Filed: 1985-01-21
Abstract: PURPOSE:To provide a flow control device which is simple in construction and controls an initial flow rate by composing a flow control path of a part of a valve body on the way of a valve path to flow the little quantity of fluid through the flow control path when the valve port of the valve body is opened. CONSTITUTION:The internal periphery of a valve path 5 opposite to the tapered periphery 21 of a valve body 8 is formed in an approximate similar shape whose tapered internal periphery 22 is slightly larger in diameter than the tapered periphery 21, and constitutes a flow control path 23. Accordingly, even when the valve port 6 of a valve body 8 is opened at the beginning of vacuum exhaust in a process chamber 1, the tapered periphery 21 of the valve body 8 keeps opposite state to the tapered internal periphery 22 of the valve path 5 at the beginning of the forward movement of the valve body 8 to form the narrow flow control path 23. Consequently suction force in a vacuum exhaust system 2 is controlled, and then acts in the process chamber 1.

Abstract: PURPOSE: To obtain an efficient leading control function with unneeded requests suppressed with respect to the leading process of a branch instruction, by enabling a memory unit to function to extract the instruction under specific conditions without sending out an instruction read request.  
     CONSTITUTION: The figure shows the look-ahead circuit. Instruction look-ahead control circuit 16 exercises a supervision over the idle state of register 11, fetches an instruction from a main memory unit not shown in the figure, and updates the contents of register 11. Now, a branch instruction is decoded by a processing part not shown in the figure and an computed branch-destination address is inputted to comparator circuit 17, so that the above-mentioned update operation will stop. On the basis of the contents of upper-limit and lower-limit address registers 13 and 14, comparator circuit 17 detects whether or not the branch-destination address is included in register 11. Judging from this result, circuit 16 determines whether or not the branch instruction should be read out from the main memory unit.

Abstract: PURPOSE:To enable to reset on way to reading of signals, by forming two regions in different depths of junctions on a semiconductor substrate, and providing a photoelectric converting element to one of the two regions and a signal  reading device to the other region, respectively. CONSTITUTION:A p type region 19 having a large junction depth and a p type region 20 having a small junction depth are formed on a semiconductor substrate 21. These two regions form a pn junction with the substrate 21. First the signal charge is stored in an n type region 15 forming a photoelectric converting part with timing t0. Then the region 19 is not completely depleted although the  adverse bias voltage is applied between the region 19 and the substrate 21 with  timing t1. On the other hand, a deep bias is applied between the region 20 and  the substrate 21, and the region 20 is depleted. Then the area between a buried  channel 16 and the region 20 is set in the forward direction, and the signal  charge within the channel 16 right under a transfer electrode 13 is all swept  away toward the substrate 21. In such a way, the residual signal charge is  swept away to the substrate 21 and a signal can be reset during the transfer of signal charge.
