Abstract: PURPOSE:To obtain a semiconductor device which has a small mounting area, a high density and a ready laminate by forming external terminals at upper and lower symmetrical positions of a chip carrier, shortcircuiting the terminals and employing a chip selection pad for not less than two external terminals. CONSTITUTION:A chip 6 is mounted in a central recess 5 of a ceramic substrate 1, internal leads 2' are formed on the surface of the substrate, and a bonding pad 8 is wired via wirings 7 to the leads 2'. A ceramic frame 3 is disposed on  the substrate 1, the leads 2' are extended on the upper and lower surfaces  through the substrate and the side faces of the frame, thereby forming upper and  lower symmetrical terminals 2. It is sealed with a metal plate 4. A chip selection pad 10 is coupled via wirings 7' to the terminals 11 of the selective terminals 11- 15. With this structure, the carrier can be readily and accurately superposed, improper bonding and displacement can be prevented, five carriers are  superposed on the terminals 11-15, thereby independently operating the chips of  the respective stages. The terminals are formed at four sides of the carrier, the upper and lower positions on the external terminals and selective terminals are  adjusted to connected the layers, thereby obtaining a small-sized high density assembly.

IPC: C02F11/12
Filed: 1989-03-02
Abstract: PURPOSE:To inexpensively and surely treat muddy water by providing a water- permeable sheet on the inner surface of a water-permeable member laid over the inner surface and furnishing an openable and closable discharge part at a part of a storage tank. CONSTITUTION:A porous concrete plate, for example, as the water-permeable member 11 is laid over the inner surface of the bottom 6 and side 4 of the storage tank 3. The water-permeable sheet 12 made of a nonwoven fabric is laid over the inner surface of the water-permeable member 11 and the inner surface of the discharge part 5 in the form of a box. When the muddy water M to be treated is injected into the storage tank 3, the water W in the muddy water M naturally permeates the sheet 12 and member 11 and flows out to the outside of the storage tank 3 from a discharge part 9 provided at the bottom 6. By this method, the running cost is reduced.

Title: Control signal transmitter
Inventor: ITOU MASAMI
IPC: H04Q9/14
Filed: 1984-03-16
Abstract: PURPOSE:To transmit monitor data to a central controller which control the whole without varying the transmission rate of control data by assigning control data and monitor data each to one of two bits in normal operation and transmitting them in case of abnormality of a controlled system so that timing information used by a transmission system is sent together with the control data. CONSTITUTION:If the controlled system becomes abnormal, a signal superposing circuit 8 detects the up-to-date start flag of control data and then closes the gate 10 of a code converting circuit to switch signal input to the circuit in the signal superposing circuit once an abnormal generation signal is inputted to the transmitter at the side of a controller MC and abnormality occurs. Further, the signal superposing circuit 8 alters the start flag of transmission format and performs transmission. This transmission format detects an error with a constant pattern at a reception side and demodulates the flag. Then, the code converting circuit 8 assigns the front one bit of two bits for the control data and the rear one bit for the monitor data instead of converting one bit of the control data into two bits, and transmits those two bits together.

Title: Cell deleting system
Inventor: NAGASHIMA SHIRO
Filed: 1992-03-06
Abstract: PURPOSE:To compress a circuit scale by deleting a cell in which a header error occurs, and writing the cell received next on a prescribed address newly. CONSTITUTION:This system is equipped with a detecting means 101 which detects the header error of received cell data. and a control means 103 which controls a storage means 102 so as to write cell data at a designated address sequentially. When the detecting means 101 detects no header error, the received cell data is written in the storage means 102 sequentially according to the address designated by the control means 103. Meanwhile, when the detecting means 101 detects the header error, the control means 103 stops write in the storage means 102. and overwrites the data to be received next at the address where a part of the cell data is already written. Therefore, the cell data having the header error can be automatically deleted.

Filed: 1991-02-20
Abstract: PURPOSE:To perform continuous insert molding by pushing up a molded product and a runner part by an ejector pin to separate the runner part from a mold and subsequently pushing up a molded product by an ejector rod. CONSTITUTION:A cavity 13 is filled with the resin from a sprue 17 and, after molding, a plate 34 is raised by a drive apparatus. The plate 34 is raised along with plates 31, 32, 33 and an ejector rod 24 and an ejector pin 26 are also raised to cut off a molded product from a resin supply part.

IPC: B23B41/00
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To finish the working of the internal spherical surface form of a work at a high sphericity accuracy. SOLUTION: The axis L2 of a rotary shaft at the supporting device side of a work is crossed to the axis L1 of a spindle at a U-shaft working machine side, and the edge 9a of a tool 9 is fitted to the rotation center O of the work. The tool 9 is moved in the U-shaft direction so that the rotating locus of the edge 9a draws a sectional circle 43a, and the spindle is rotated, and as a result, parts S1 and S1 are cut in to projection ends 42 and 42a respectively. Then, by rotating the work 90 deg. making the L2 as the shaft from that part, the upper half and the lower half of the sectional circle 43a are to draw the locus of 1/4 of a spherical form 43 relatively, to the projection ends 42 and 42a, respectively, and parts S2 and S2 interfering with them are cut off at point- simmetrically respectively.  When the work is rotated 90 deg. further, the sector form part of remaining 1/4 are cut off, and the parts 44 and 44 of the internal spherical surface form interferring with the spherical form 43 are cut off respectively, at the opposing surfaces of the projection ends 42 and 42a.

IPC: G01R1/073
Filed: 1992-03-09
Abstract: PURPOSE: To obtain a hold-down gate which is used together with a circuit board testing device. CONSTITUTION: This hold-down gate includes a fixed frame 9 which is fitted movably to a probe plate 5. The probe plate is arranged tightly on the surface of the testing device. The fixed frame includes a means which supplies compressed fluid to a piston chamber and releases the liquid from it. A piston 21 has one end part which is arranged in the piston chamber 11 and projected downward from the fixed chamber, and is fitted tightly to a movable frame 13. The movable frame is large enough t contact the periphery of the circuit board which is being tested. Therefore, when the circuit board is placed on the probe plate 5, the fixed frame moves and the movable frame abuts against the periphery of the circuit board. Then the fixed frame is latched and becomes unable to further move. Then the compressed liquid is supplied to the piston chamber of the fixed frame to press the piston down.

Abstract: PURPOSE:To reinforce an alveolar bone, by mounting a piezoelectric material to the inner surface of a denture base in a partially exposed state. CONSTITUTION:A denture 1 is composed of a material such as ceramic and an artificial tooth 4 is fixed to a denture base 3. A piezoelectric material 8 is fixed to the denture base 3 and a part of the piezoelectric material 8 is partially exposed from the inner surface of the denture base 3 at the position corresponding to the apex 6a of an alveolar bone. Other piezoelectric materials 9, 10 are similarly fixed on both sides of the piezoelectric material 8. The denture 1 thus constituted is mounted to an alveolus 2 in use. When a thing is chewed by this denture 1, since the piezoelectric materials 8, 9, 10 are partially exposed from the inner surface of the recessed part 5 of the denture base 3, the electromotive forces of said piezoelectric materials 8, 9, 10 are applied to a mucous membrane 7 to act on the alveolar bone 6. By this method, the apex 6a of the alveolar bone 6 and the vicinity thereof are reinforced and the alveolar bone 6 is certainly prevented from becoming lean to recede.
