Abstract: PROBLEM TO BE SOLVED: To provide a measuring circuit which can measure a characteristic without a current-dependent error by a method wherein the potential difference between a plurality of input terminals is detected by an amplifier and a detected result is fed back so as to eliminate the detected potential difference. SOLUTION: A current source 11 is connected across an input terminal 1 and an output terminal 3, and a prescribed current is made to flow to the direction of the output terminal 3 from the input terminal 1.

Abstract: PROBLEM TO BE SOLVED: To reduce the burden on an operator and to prevent the transmission error or the like of facsimile by overwriting an additional image in the terminal area of image data when the absence of effective image information in that area is discriminated. SOLUTION: An image information presence/absence discriminating part 8 discriminates the presence/absence of effective image information in a terminal area A of transmission image data 11 stored in a transmission image data storage part 3. The terminal area A is defined as an area within L lines from the head of transmission image data 11, for example and when all the L lines are discriminated as ineffective image information like a blank and the effective image information exists in the remaining hatched section, for example, at such a time, a transmission source information image 12 is overwritten on the ineffective image information. Therefore, the transmission source image information 12 for L lines is transmitted while being linked with effective image information for P-L lines. When all the P lines are effective image information, on the other hand, the transmission source information image 12 for L lines is connected to the effective image information.

Filed: 1980-07-16
Abstract: PURPOSE:To considerably inhibit the shrinkage and to reduce a change in the outside diameter by slowly vitrifying moving rodlike oxide powder deposited in a powder depositing process with a plurality of heat treating units arranged in succession along the moving direction. CONSTITUTION:Oxide powder produced with gaseous starting materials and an oxyhydrogen flame sprayed from a burner 5 having a multitubed structure is deposited on the lower end of a rotator 6 to form rodlike oxide powder A. The rotator is slowly moved upward in synchronism with the deposition speed of oxide powder, and the powder A enters a heat treating unit 7, where it is subjected to primary heat treatment. Since the heat treatment is carried out at a low temp. such as <= about 1,200 deg.C, the shrinkage rate of the rodlike oxide powder A is low. Next, the powder A enters a heat treating unit 8, where it is thoroughly vitrified by secondary heat treatment. This heat treatment is carried out at >= about 1,300 deg.C, yet the shrinkage rate of the powder A is low since the powder has been subjected to the primary heat treatment.

Abstract: PURPOSE:To easily transmit data and response data, by fetching the transmitting data when this devide itself is designated by the address just before instruction data and transmitting the response data by changing the locations of addresses and instruction data to each other. CONSTITUTION:When one of the addresses of an address area 4a is equal to its own address, transmitting data are fetched. Unless otherwise the its own address in the area 4a is the last one, in other words, unless otherwise its own address is just before a stopper address, the fetched transmitting data are again sent out. At the time of resending, its own address of the area 4a is changed to that of the device just before its own device and moved to the last location. Then the remaining addresses are shifted up and the next gateway and controller are set to designated states. If the fetched data are those requesting response data, the addresses of the area 4a, namely, the addresses from the 2nd stopper address to the last address are changed their locations upside down and an entirely reverse transmitting route is designated. Then the addresses are transmitted together with the response data.

Abstract: PROBLEM TO BE SOLVED: To form an excellent solder fillet making the beast use of the advantage of a gull-wing outer lead part so as to enhance a soldered joint in mechanical strength by a method wherein the tip of the gull-wing outer lead part is set at an angle with the surface of an object of connection. SOLUTION: The tip sides of outer leads 2 which are each bent like a gull wing are twisted by an angle of 90 deg. respectively, and the tips of the twisted sides are set flat. When a package 1 is mounted on a board, the flat tips of the twisted tip sides of the outer leads 2 are connected with solder to lands provided on a printed wiring board as objects of connection. At this point, the flat planes of the tips which are soldered are kept vertical to the mounting surface of a printed wiring board and substantially higher than usual to the printed wiring board. Therefore, molten solder is capable of rising higher than usual, so that a solder fillet large enough in size can be formed.

Title: Semiconductor device
Inventor: AKIYAMA NOBORU
IPC: H01L27/10
Filed: 1989-04-19
Abstract: PURPOSE:To reduce a cell area and to improve integration by forming a static type memory cell of diodes having different forward voltages and internal series resistors, transfer MOS transistor, and a resistor. CONSTITUTION:A diode D110 having a large forward voltage and a small series resistance, and a diode D220 having a small forward voltage and a large series resistance are connected in parallel, and the value of a resistor R40 is so selected that the voltage of an anode terminal is smaller than V1, i.e., no current flows. Here, when a voltage larger than an anode terminal V1 is applied by using a transfer MOS transistor 30, a current also flows to the D1. Since the series resistance is small, the current flowing to the D1 is dominant. Even if voltage application is stopped, the voltage of an anode terminal is stabilized at a value slightly larger than the V1. When the voltage V1' smaller than V1 is applied to the anode terminal, no current again flows to the D1, and the voltage of the anode terminal is stabilized at the value slightly larger than the forward voltage of the D2. Thus, it can be used as a static memory to reduce a cell area and to be highly integrated.

Next, comparator 5 detects which content of register 4a or 4b is smaller and the smaller one is inputted to ROM7. In ROM7, part of the calculation result of the distance is stored corresponding to the input of address x 2 -x 1  or y 2 -y 1  and outputs, e.g. (2 1/2 -1). (y 2 -y 1 ) and x 2 -x 1  are added by adder 8, thereby obtaining the distance.
