Patent JP-S6371669-A (JP)
Title: Inspecting method for electronic circuit device
Inventor: YOSHIDA HIROTO
IPC: G01R31/26
Filed: 1986-09-16
Abstract: PURPOSE:To check an electric short circuit in an integrated circuit device to be inspected by dividing all external terminals in the integrated circuit to be measured by two groups and connecting all external terminals of the respective groups so that the they are at the same potential, applying a constant DC voltage to one terminal group and connecting the other terminal group to a specific reference potential point, and measuring a current flowing between the terminal groups. CONSTITUTION:A voltage source 11 is set to a 0.3V voltage and connected to a positive power terminal 7 through an ammeter 12. When a path where a current flows from the terminal 7 to another external terminal is considered, at least one P-N junction (forward) should be passed as to external terminals 1-4, but no forward current flows through the P-N junction with the 0.3V voltage. When a voltage lower than the built-in potential of the P-N junction is selected as the set voltage of the voltage source 11, no current flows at the time of a normally manufactured integrated circuit device. Consequently, detection sensitivity to a nonconforming article where a slight leak current is generated between external terminals can be improved.
Patent JP-S6276454-A (JP)
Title: Method for deciding quality of spot-welded part
Inventor: UMEYAMA YUKICHI
IPC: G01N29/04
Filed: 1985-09-30
Abstract: PURPOSE:To easily discriminate a welded part from an unwelded part by projecting a ultrasonic pulse at every certain period, comparing a transmissive or reflection waveform with a reference one so as to execute a primary 'good or not' decision and deciding a corresponding welded part to be good when the good quality decision continues over a reference number. CONSTITUTION:Assuming that a welding pitch and speed of a structure which is spot-welded roughly at a certain interval and moves at an approximately constant speed, and the projection cycle of a ultrasonic pulse are P(mm), V(m/min) and I(Hz), respectively, the moving distance S(mm) up to an object before a next ultrasonic pulse is projected is as follows: S=(1,000/60)(V/I). For a 0.8mm steel sheet which is roll-formed at 1,000Hz and V=30m/min and spot-welded at 20-30mm pitch, S=0.5. In this case, since an excellent longitudinal diameter of a nugget is 5-7mm, a transmissive waveform to be decided good quality is obtained after the good quality decision continues 10-14 times. If the nugget forming is small and of three mm, the good quality decision only continues six times. Namely, if the good quality decision continues more than ten times at the primary 'good or not' decision, the welded part is decided to be good.

Title: Capacitor with protective device
Inventor: YAMAGUCHI SEIJI
IPC: H01G2/18
Filed: 1988-08-31
Abstract: PURPOSE:To prevent lead pieces from becoming conductive again and to make it possible to let a protective device work reliably by a method wherein, in a capacitor with a protective device, a gas-permeating and liquid-shutting off film is provided on the inner cover. CONSTITUTION:A gas-permeating and liquid-shutting off film 9, which is provided on an inner cover 5, is made of paper and fiber, a porous film and a sheet of penetrable etching foil. A capacitor 11 generates gas by the reaction of the impregnated liquid when it is used. This gas passes through the film 9 and filled up in the space formed by the external cover 3 and the inner cover 5. When the gas pressure in the space goes up, a case 1 and the external cover 3 swell out, lead pieces 7 are pulled and they are cut at a weak part 8. As the impregnated liquid can be shut off by the film 9, it does not infiltrate into the space. Accordingly, the lead pieces 7 can be prevented from becoming conductive again due to the infiltrated liquid.

Title: Output circuit
Inventor: NAKAJIMA TOSHIO
IPC: H03K19/0948
Filed: 1984-10-17
Abstract: PURPOSE:To eliminate the through-current flowing between high and low power supplies by connecting respectively P and N-channel MOSes in series in two stages, shifting the phase of an input signal to each MOS so as to eliminate the period when all MOSes are turned on at the same time. CONSTITUTION:P-channel MOSes 3, 2 and N-channel MOSes 4, 5 form respectively series circuits. A resistor 9 and a capacitor 10 form a delay circuit to retard an input signal at a terminal 7 by a time TD (a time the same as the time DELTAT of the intermediate level or slightly longer). When the input signal is applied, the said delay signal (figure 2) is fed to the MOS2, 5. Since the input signal of '0' is fed to all the MOSes during the period T1, the MOS2, 3 are turned on, the MOS4, 5 are turned off and an output of '1' in figure 3 is outputted to a signal output terminal 8. The input signal 1 is at the intermediate level during the next period T2, the MOSes 2, 3 are turned on and the MOS5 is turned off. Similarly, at the periods T1-T5 all the MOSes are not turned on at the same time. At periods T6-T8 as well as the period T9, all the MOSes are not turned on at the same time.

Title: Semiconductor integrated circuit
Inventor: KATSUNO KUNIO
IPC: H01L21/60
Filed: 1986-09-16
Abstract: PURPOSE:To exclude failures like the cutting remnant at the time of cutting process without deteriorating the functions of input-output terminals arranged in a scribe region, by a method wherein a terminal (input-output terminal) which is formed in a scribe region and intended for delivering and receiving of signal for external part is provided with slits whose one segment is shorter than or equal to a specified length. CONSTITUTION:An input-output terminal arranged in a scribe region 2 is provided with slits which are vertical to the direction of cutting. As the result of arrangement of slits in the input-output terminal 1, it does not occur that a continuous force is applied, at the time of cutting, to a metal material constituting the terminal. As the result, both cutting remnant and exfoliation are reduced. When the slit width is made wider, the cutting force applying to one terminal becomes smaller and the cutting remant is reduced. However, when it is necessary to make a pin and the like bring into contact with the terminal, the case where the contact is impossible happens, if the slit is made wider than a necessary width, and the terminal cannot satisfy its functions. Consequently, 20mum or less is suitable for the width of slit.

IPC: C10N40/18
Filed: 1982-12-14
Abstract: PURPOSE:To provide a magnetic recording medium causing no increase in the coefft. of friction and having high traveling durability by incorporating 11-21C fatty acid as a dispersant into a back layer contg. inorg. powder dispersed in a binder. CONSTITUTION:11-21C satd. or unsatd. fatty acid is used in this invention. A mixture of fatty acids which are different from each other in the number of C atoms or a mixture of satd. fatty acid with unsatd. fatty acid may be used. In case of <11C fatty acid, favorable results are not produced with respect to the traveling performance of a tape. In case of >21C fatty acid, when a back layer is formed, the fatty acid deposits on the surface of the tape as white crystals, and it causes dropout and other unfavorable influence. The preferred average particle size of inorg. powder used in this invention is <=0.8mum, especially <=0.4mum. The preferred thickness of the back layer is 0.3-1.5mum, and <=0.10mum surface roughness Ra of the back layer produces favorable results.

Title: Soldering method for circuit component
Inventor: FUKUSHIMA HIROSHI
IPC: H01F41/10
Filed: 1988-08-31
Abstract: PURPOSE:To solder whole terminal pins uniformly by simultaneously moving them in a linear direction while applying a rotary operation to a circuit component. CONSTITUTION:A coil component 1 is moved down in a direction of an arrow while rotating, and its terminal pins 4 are dipped in molten solder 5. Subsequently, the component 1 is moved leftward while rotating. The pins 4 are moved in the molten solder 5 while they are deviated with respect to the moving direction, and all sufficiently immersed in the solder 5. Since the component is moved linearly in the molten solder while rotating around its own axis, the pins disposed at the rear are not affected by the influence of the molten solder flow generated by the terminal pins disposed at the front, and the individual pins are sufficiently immersed in the molten solder to provide the component which is satisfactorily soldered.
