Abstract: PURPOSE:To measure speedily the position of a target body by receiving a linear FM signal radiated from the target at >=3 points, calculating two presence directions of the target body from the frequency difference between received signals, and measuring the position of the target body as the intersection of the directions. CONSTITUTION:The linear FM signal radiated from the target 1 is received by >=3 antennas 2, 3, and 19 and the difference frequency between received signals of two antennas is calculated to obtain the presence direction theta of the target body based on the two points 2 and 3 where the antennas are installed. Further, the difference frequency between received signals of the two antennas 3 and 19 in a different combination is calculated to obtain the presence direction of the target body 1 based upon the two points 3 and 19 where those antennas are installed. Thus, the position to the antenna installation point of the target body is measured as the intersection of said two presence directions.

Title: Manufacture of semiconductor device
Inventor: NAKADA TAKAAKI
IPC: H01L21/331
Filed: 1979-06-07
Abstract: PURPOSE:To suppress the redistribution of base impurity in a semiconductor device by forming a base, then implanting impurity ion to the emitter region, and thereafter irradiating a laser beam to activate the emitter region. CONSTITUTION:A P-type base region 2 and an insulating layer 3 are formed on an N-type substrate 1. Then, an N-type impurity ion is implanted in shallow depth in high density to form an emitter region 4 therein. Thereafter, a laser beam is irradiated in pulse state to activate the emitter region 4 and to form an emitter. At this time the base surface and the emitter region are once molten and again recrystallized and grown. Since this step is instantaneously executed, base distribution of impurity is not almost altered. Subsequently, base and emitter electrodes 5, 6 are formed. Since the base impurity redistribution is suppressed, it can obtain a transistor having narrow width of base.

IPC: B22D11/06
Filed: 1979-06-08
Abstract: PURPOSE: To prevent the occurrence of cracking and obtain the product of the thickness relatively even in the width direction by providing the concave circumferential grooves of a width wider than the desired sheet product on the surfaces of the rolls which directly roll molten metal.  
     CONSTITUTION: Concave circumferential grooves 2, 2 of a width wider than the desired product width, for xample, arc form, are provided on the surfaces of a pair of rolls 1, 1 which roll the molten metal of brittle material such as Fe-Si-Al- base alloy directly to a sheet. While these rolls 1, 1 are being revolved in the arrow direction, molten metal is passed and cooled in the spacing between the rolls, whereby the intended sheet product is obtained. These provide effect such as the decrease in local screw-down owing to the expansion of the rolls, and the increase in thermal capacity of the central part in the width direction where cracking tends to occur at the passing of molten metal, and this helps prevent the occurrence of cracking even with a much thinner sheet product.

That is, the multiplexing transmission device 20 judges the kind of the signal by the kind of the error detecting signal.  When the kind of the signal is sorted once, the arrival timing of the signal which succeedingly arrives is judged so that the kind of the received signal is sorted.

IPC: C03B35/20
Filed: 1990-03-22
Abstract: PURPOSE:To prevent a plate material from sagging by empty weight and to subject the plate material to bending molding in high accuracy by receiving periphery of the plate material separated from a mold by a quenching ring, simultaneously by a pad ring, parting the pad ring from the plate material and approximately simultaneously cooling the plate material. CONSTITUTION:A pad ring 12 is liftably set in a quenching ring 10 and the pad ring 12 is positioned on at the same plane on which the quenching ring 10 place a plate material (glass plate) 17. Consequently, the plate material 17 separated from a mold is supported on the ring 12. In the state, the plate material 17 is transported to a cooling station, the ring 12 is parted from the plate material 17 and approximately simultaneously the plate material 17 is cooled. Therefore, since sagging of the plate material 17 by empty weight can be prevented by the ring 12, the molding face of the mold can be made into approximately the same shape as the curved surface of final shape of the plate material 17. For that reason, molding accuracy is improved and even if the plate material 17 is made into S-shape, the plate material can be subjected to bending molding in a complicated shape in higher accuracy than existing method.

Abstract: PURPOSE:To reduce a layout area and to reduce the charge/discharge current of gate capacity by performing desired connection by using a few number of transistors, and performing the input/output of data with an adjacent register in the H period of a control signal. CONSTITUTION:In the period of a clock signal CK=H (Vcc positive level), the transistor Tn1 is turned on and output data in a register at a preceding stage is written on a latch circuit consisting of inverters INV1 and INV2. Simultaneously, data held at the latch circuit consisting of inverters INV3 and INV4 is outputted to an output signal Di via transistors Tn2, Tn3, and Tn4. In the period of the clock CK=L, a transistor Tp1 is turned on, and the data in the latch circuit (INV1 and INV2) is written on the latch circuit (INV3 and INV4). At this time, when potential at a point A is set at an L, the Tn3 is turned on, and the L of the CK appears at a Di, then, the Di goes to the L. Also, when the potential at the point A is set at the H, the Tn3 is turned off, and the Tn4 is turned on, therefore, it is goes to Di=L. In the constitution, the number of the transistors can be reduced remarkably.
