Title: Thin-film inductor and thin-film transformer
Inventor: MINO MASATO
IPC: H01F17/00
Filed: 1993-08-23
Abstract: PURPOSE:To suppress magnetic saturation of a magnetic body part and then reduce the loss of the magnetic body and the loss caused by coil resistance in a thin-film inductor and a thin-film transformer. CONSTITUTION:One second magnetic film 6 is in rectangular shape and a first magnetic film 3 and the second magnetic film 6 are connected at the entire inside of the inner periphery of a flat surface coil 4 and at two locations outside the outer periphery out of magnetic films 3 and 6 holding spiral-shaped flat surface coils 4 via an insulation film 2, thus forming a closed magnetic path structure. With this structure, the sectional area of the magnetic film at the connection part between the first magnetic film 3 and the second magnetic film 6 is nearly equal at the connection part outside the outer periphery and that inside the inner periphery, thus relaxing magnetic saturation in the magnetic film at the inner-periphery part. The magnetic saturation reduces the increase in coil resistance due to the loss of the magnetic body and leakage magnetic flux. Also, the magnetic body of the outer-periphery part can be effectively utilized and excitation conditions can be set highly, thus improving high-frequency characteristics of a thin-film inductor, etc.

IPC: F24H3/04
Filed: 1989-08-14
Abstract: PURPOSE:To prevent the vibration of a pump which is a driving source from being transmitted to other parts by mounting the pump to an oil level gage via a buffer material. CONSTITUTION:When an external force in applied to the pump 3 of, for exam ple, an oil hot air heater, the same force is also applied to a york 4.

Title: Operational amplifier
Inventor: HAYAKAWA TATSUO
IPC: H03F3/345
Filed: 1986-09-03
Abstract: PURPOSE:To drive a >= 1000 pF capacity in a wide range without using a PNP with a poor frequency characteristic by using the composite transistor of a channel P MOS and an NPN transistor for an AC signal bus. CONSTITUTION:The composite transistor 5 where the channel P MOS transistor M1 and the NPN transistor Q1 are connected and a composite transistor 6 where the channel P MOS transistor M is connected to the PNP transistor Q2 are used for an initially staged amplifier. Where the propagation conductance of the MOS and the current amplification factor of the NPN transistor are denoted as gmM and hFE, respectively, the propagation conductance GM of the composite transistor is shown by GM = hFE X gmM. Since the current amplification factor hFE is about >= 100, a great propagation conductance can be obtained. As for the unity gain frequency fuM of the MOS, the frequency characteristic of the composite transistor is improved by inserting breeder resistances R1 and R2 between the base and emitter of the NPN, for instance.

Abstract: PURPOSE:To secure a high reading factor by increasing the widths of the same grooves having the same width compared with the width of a projecting part held between the two grooves. CONSTITUTION:A bar code pattern 7 consisting of plural grooves 2a, 2b... is carved on the surface of a bar code plate 1 made of the soft steel. Then the relations t1>t3 and t2>t4 are satisfied among the widths t1 and t2 of the grooves 2a and 2b of the pattern 7 and the widths t3 and t4 of the projecting parts 3a and 3b held between the grooves 2a and 2b corresponding to the bars having the same widths as the grooves 2a and 2b respectively. For instance, the widths of the grooves 2a and 2b are set larger than the widths of parts 3a and 3b. Therefore the interval ratio of the extreme magnetic flux density is set at 1:2.5 between the grooves corresponding to the thick and thin bars. As a result, the pattern 7 can be read with a high reading factor.
