Title: Ceramic base of ceramic package
Inventor: SUGIMOTO MITSUO
IPC: H01L23/08
Filed: 1989-10-16
Abstract: PURPOSE:To restrain a lead from deviating both at a pressure-bonding process and a sealing process and to prevent the lead from being mis-recognized at wire bonding by a method wherein a comb-like rugged part is provided to a lead pressure-bonding plane which constitutes a ceramic base surrounding a cavity. CONSTITUTION:In a ceramic base 1 of a semiconductor device ceramic package, as the cross sections A-A' and B-B' of a figure (a) are shown by figures (b) and (c) respectively, a comb-like rugged part 4 is provided to a lead pressure- bonding plane 3 at a boundary between the plane 3 and a cavity 2 of the base 1 surrounding the cavity 2. After a sealing glass 5 is applied onto the lead pressure-fixing plane 3 (figure d), the end of a lead is inserted into the recess of the rugged part 4 and pressure-bonded. By this setup, the lead 6 is prevented from deviating both at the pressure-bonding process and the sealing process of it. The lead 6 is prevented from being mis-recognized due to the irregular reflection of light when it is illuminated at wire bonding.

Filed: 1986-11-14
Abstract: PURPOSE:To improve information describing efficiency and to realize a noncontact reading action by showing each position of the identification information on an individual in the form of the size of the area of an object having the variable density different from a background and the contents of information in the form of the number of small objects having the same variable density as the background within said object. CONSTITUTION:A camera 2 fetches a code printed matter 1 as a picture and a picture recognizing device 3 consists of an LSI which binarizes the picture of the code fetched by the camera 2. Each position of the identification information on an individual is shown in the size of the area of an object having the variable density different from a background. Then the information contents are shown in the form of the number of small objects having the same variable density as the background within said object. The areas and number of these object are obtained just by counting the number of connected same picture elements. While the objects showing each position of the identification information have their areas of the same order and it is possible to discriminate whether the variable density is inverted or not by checking the variance of variable density within an object.

Title: Method of feeding out slender solid material such as fish from tank
Inventor: HAYASHI TAKESHI
IPC: A01K63/00
Filed: 1985-11-30
Abstract: PURPOSE:To smoothly guide long and narrow solid material to a transfer duct without jamming by producing a difference in speed between a rectilinear current rectilinearly flowing froma tank into a transfer duct and a branch flowing from the tank and curveing into the duct. CONSTITUTION:The base of a tank 1 is sloped downward to a transfer duct 9 connecting portion so that solid material can slide into the duct more smoothly. The transfer duct 9 is located at the corner portion of the inner wall surfacel of a tank, and extended with respect to the base and one-side peripheral wall in its extending direction. In this arrangement, the speed of a rectilinear current flowing into the transfer duct rectilinearly is higher than the speed of a branch curvi into the transfer duct, so that the direction of a long solid material is adjusted properly by such a difference in flowing speed. Therefore, at the time of forcing a difference in flowing speed. Therefore, at the time of forcing a long and narrow solid material to flowinto the transfer duct from the tank, both ends of the solid mateial is not caught in an opening portion of the transfer duct like a bridge, and even if it is done so, only one end is caught therein and the other end is slid into the transfer duct. Thus, the solid material can be guided into the transfer duct smoothly.

Abstract: PURPOSE:To provide the safe device which prohibits the leakage of large light energy from a damage point by introducing a part of amplified signal light as a signal for detecting disconnection from an optical branching device, detecting the light intensity thereof and controlling a exciting light source. CONSTITUTION:A part of the amplified signal light taken out by the optical branching device 24 is introduced as the signal light for detecting disconnection via an optical fiber 17 for detection to a light receiving element 16 and the light power of the signal light for detecting disconnection is kept monitored at all times by a controller 28. The exciting light is no longer supplied to an optical fiber 19 for amplification or the amt. of the supply decreases when an optical fiber 15 for transmission to conduct the exciting light is put into a broken state. The intensity of the signal light for detecting disconnection eventually decreases. The operation of a driving device 27 is stopped to stop the oscillation from the exciting light source 14 when this state is detected by the light receiving element 16 and, therefore, no problems arise even if an operator erroneously peeps the damaged point.
