IPC: G06F9/445
Filed: 1982-11-19
Abstract: PURPOSE:To supply a batch to many terminal controllers simultaneously, by providing a batch control circuit including an RAM for batch area besides a normally used ROM. CONSTITUTION:When a cahnge position occurs, change data is sent from a center controller. A receiving part 1 analyzes this data, and an RAM writing part 3 writes it in an RAM2 for batch area. Next, when a switching indication is sent from the center controller, a wait processing part 4 subjects the control circuit to the wait processing after the end of an executing processing. A relay A is operated to switch its contact (a), and the ROM is disconnected, and the RAM2 is connected. After the end of switching, wait is released. When wait is released, the control circuit uses data of the RAM2 to execute a program. Thus, a batch program is supplied to many terminal controllers easily.

Then, the surface of the barrier metal layer 4 is coated uniformly with a positive-type photoresist; a photoresist film 5 is formed; after that, the photoresist film 5 in a hollow part of the barrier metal layer 4, i.e., a solder bump formation part, is removed. Then, a solder 6a of a prescribed amount is bonded to the surface of the exposed barrier metal layer 4. Then, the barrier metal layer 4 other than a part to which the solder has been bonded is removed. That is to say, when the solder 6a on the barrier metal layer is made to reflow, the solder 6a is transformed into a spherical solder bump 6 by surface tension while its shape is being retained by a glass film 7.

Title: Valuable article packaged body
Inventor: TAWARA SHIGEHIKO
IPC: B65D75/26
Filed: 1990-08-01
Abstract: PURPOSE:To easily discriminate whether a packaged article is real or not, give a special appearance effect and make a display element be destroyed when two sheets constituting the packaged body are attempted to be separated by bonding the other sheet material on the hologram relief surface of a reflective relief hologram sheet. CONSTITUTION:A valuable article 1 is placed between an upper side sheet material 2 and a lower side sheet material 3, and sealed by adhering the outer peripheries of both sheet materials 2, 3 by an adherent layer 7.

Title: Interference wave extracting circuit
Inventor: HASEGAWA JUNICHI
IPC: H04B1/10
Filed: 1987-08-18
Abstract: PURPOSE:To prevent the effect onto a digital modulation wave by using a narrow band pass filter even if a frequency fluctuation exists in an FM interference wave component in using a phase locked loop. CONSTITUTION:The output frequency f1 of a nearby component extraction means 24 is kept constant even if the frequency of the inputted FM interference wave component is fluctuated by using the phase locked loop comprising a 1st frequency converter 23, the nearby component extraction means 24, the reference oscillator 27, the control signal generating means 26 and the variable frequency oscillator 25. In this case, the synchronizing range of the phase locked loop is kept in the frequency fluctuation range of the FM interference component to extract the carrier component synchronously with the FM interference component even if the frequency of the FM interference wave component is fluctuated. That is, even in the presence of the frequency fluctuation of the FM interference wave component, the bandwidth of the nearby component extraction means 24 is made narrow by using the phase locked loop. Thus, the effect onto a digital modulation wave is almost less and the carrier synchronously with the FM interference wave component is obtained surely from the variable frequency oscillator 25.

Title: Fine combined catalyst wire
Inventor: YAMAZAKI TATSUO
IPC: B01J35/06
Filed: 1990-07-31
Abstract: PURPOSE:To obtain a fine combined catalyst wire having a significant economical effect by using Pt or a Pt alloy as a catalyst metal as the shell material of a fine combined catalyst wire and Nb or an Nb alloy as the core material. CONSTITUTION:Pt forming the pore part of the conventional fine solid Pt catalyst wire does not directly take part in catalytic action and becomes a sort of dead stock. When the Pt is replaced with Nb or an Nb alloy so as to obtain a fine combined catalyst wire, the amt. of Pt used can be considerably reduced without deteriorating the catalytic action and structural strength. Since it is made unnecessary to alloy Pt by adding Rh, the cost of production can be considerably reduced, Pt and Rh as rare resources are prevented from becoming dead stock and a significant economical effect can be produced.

Abstract: PURPOSE:To obtain a spatially homogeneous magnetic field distribution by regulating the coil width in respect of the defecting radial direction of a deflecting electromagnet which consists of a pair of upper and lower coils by using the magnetic field distribution feature. CONSTITUTION:A deflecting electromagnet 3a is composed of an upper coil 31a and a lower coil 32a. The change of the magnetic field distribution by changing the sizes R1 to R4 in the figure to change the coil width has been analyzed in a magnetic field computation simulation. The magnetic field distribution curve near x=0 shows a projection downward when the coil width W is large. By making the coil width W the smaller, the magnetic field distribution shows a projection upward. When the coil is disposed to have the coil width changing from the downward projection to the upward projection, there is an area to show the magnetic field of a good evenness. When the coil width is made further smaller, the second highly even magnetic field area is found. The area shows the properties of a strong magnetic field intensity more than 3 Tesla, and a high utilization efficiency of the magnetomotive force of the deflecting electromagnet 3a, although the part of the high magnetic field homogeneity is narrow.

Abstract: PURPOSE:To relieve the positional deviation between a bump and pad so as to make sure the electrical connection between the bump and pad at the time of performing burn-in tests. CONSTITUTION:A film-like flexible first conductive circuit board Al is put on a second conductive circuit board A2 having a coefficient of thermal expansion which is equal or close to that of a wafer 100. A lead 2a electrically connected to a bump 4 is connected to a terminal 8d. The signal lines of the conductive wiring 8 corresponding to the pad 101 of each IC are connected in parallel to an electric characteristic inspecting device through resistors. Capacitors are connected in parallel with the resistors. When the bump 4 comes into contact with the pad 101 of one IC, a signal having a specific frequency is inputted to the pad 101 from the electric characteristic inspecting device and the IC is inspected for electric characteristics. Therefore, a load voltage can be applied across the IC and, in addition, the occurrence of an overcurrent resulting from the short-circuiting of the IC circuit can be prevented and the occurrence of noise can be reduced by the capacitors. Moreover, the number of input-output lines to the electric characteristic inspecting device can be reduced.

IPC: G01B5/02
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To obtain a stack length measuring instrument that can reduce the time required to measure the stack length and has a simple structure. SOLUTION: The measuring instrument consists of a chute 12, a straight- advance feeder 14, a stopper 15, a measuring probe 3 whose upper edge is in contact with a length measuring instrument 2 and a nib 3a at a lower edge rises relative to a pellet and which slides due to a ball screw 4, a measurement block 5 that becomes a reference for measuring a stack length, and a transfer 16. Then, the stack length is obtained by subtracting the distance which the measuring probe 3 moves from the time when the stack length starts to be measured to the time when the pellet is pressed from the distance from the measurement block 5 to the nib 3a when the stack length starts to be measured, thus reducing time required to measure the stack length and reducing the length of the length measuring instrument 2.
