Patent JP-S56161647-A (JP)
Title: Semiconductor device
Inventor: SOGA TASAO
IPC: H01L23/367
Filed: 1980-05-16
Abstract: PURPOSE:To decrease the thermal resistance and improve the power cycle-proof of a high power transistor by a method wherein an element is fixed to a stem provided with, for example, copper-carbon fiber which is almost equivalent in the coefficient of thermal expansion and high in thermal conductivity as compared with the element, in the semiconductor device comprising a heat sink and the stem fixed with the heat sink. CONSTITUTION:For example, a substrate of the composite fiber of 50% copper and 50% carbon in the volume ratio is manufactured by plain weaving a fiber bundle 13 of the copper-plated carbon fiber or 7-8mum diameter and hot-pressing the fiber bundles superimposed by two sheets. The composite substrate can be made 2.0W/cm deg.C in the thermal conductivity and 3.5-4.0X10<-6>/ deg.C in the coefficient of thermal expansion. The composite substrate is silver-soldered to an iron stem to form the stem 11 after being Ni-plated. A chip of the power element is fixed by a highly-heated solder and covered with a cap 12 to be made the element. Thereby, the device can be constructed in the low thermal resistance and the power cycle- proof, and in addition, the cost is reduced.

Title: Dry etching
Inventor: SATO HITOAKI
IPC: H01L21/302
Filed: 1987-03-20
Abstract: PURPOSE:To improve the foundation selectivity significantly by reducing a microwave application rate and a bias voltage immediately after a treated object is etched. CONSTITUTION:While a treated object 10 is etched, a microwave application rate and a bias voltage are maintained at 300-500W and 50-250V respectively and, immediately after the etching of the treated object is finished, the microwave application rate and the bias voltage are reduced to 150-300W and 5-50V respectively. By reducing the microwave application rate and the bias voltage after the etching of the treated object 10 is finished as mentioned above, the rate of the microwave applied to a foundation 13 exposed after the etching of the treated object 10 is reduced. With this constitution, the ion quantity is reduced and the ion implantation energy into the treated object 10 is also reduced so that the foundation selectivity can be improved.

The tape displacement structures are provided in association with the transducer head, engaging the received tape to bias the tape to a tape travel path 35 retracted from the tape travel path. The retracted tape travel path is separated from the transducer head. The tape carriers separate the tape from the transducer head to traverse the tape displacement structures.  The tape carriers prevent transducer abrasion and transducer contamination caused by contact of the tape moving and rubbing the transducer head.

IPC: F23C10/02
Filed: 1991-03-28
Abstract: PURPOSE: To improve heat efficiency by providing heat exchange means for removing heat from a separation material in a second compartment chamber, by permitting the separation material to flow from first to a second compartment chamber, from a second conduit to a furnace region at a first position of control means, and from a first compartment chamber to the furnace region through the first conduit at a second position. CONSTITUTION: Typically, a slide gate valve 59a is located at a close position, and a valve 59b at an open position. Accordingly, a separated assembly of saturated flue gas separated by cyclone separation flows into a compartment chamber 58b from a dip leg, and passes through a compartment chamber 58c after passage through an opening 56e. A solid in the compartment chamber 58c removes heat traversing a heat exchange pipe 64, and emanates to a conduit 72b through an opening 42c to return to an enclosing structure. Further, upon initial starting and upon low load the slide gate valve 59b is closed, and the solid from the dip leg is passed to the compartment chamber 58b, and is directed to the enclosing structure through the opening 42b and the conduit 72a, and is returned to the enclosing structure without passage through the compartment chamber 58c.

Title: Magnetic picture recording and reproducing device
Inventor: YAMAMOTO YOSHIHITO
IPC: G11B15/467
Filed: 1987-03-19
Abstract: PURPOSE:To obtain a stable reproduced picture which is completely free from noise and has a high S/N, by sampling a reproduced video signal in plural positions and performing the tracking control so that the minimum sampled value is maximum. CONSTITUTION:When a track pattern T recorded on a magnetic tape is different from a head locus H for reproducing, the reproduced video signal is amplified, and a reproduced signal (a) due to envelope detection waves to have parts in the high level and those in the low level. This reproduced video signal is sampled in plural positions, whose number is large as much as possible, in one field section to detect the minimum value, and this value is prescribed as the reproduced video signal level of one field. Tracking of a servo circuit is automatically changed, and preceding and succeeding reproduced video signal levels are compared with each other, and tracking is so controlled that the level is maximum. Thus, the stable reproduced picture which is completely free from noise and has a high S/N is obtained unless a tape where noise cannot be eliminated by the manual tracking generation is used.

Title: Dust collecting device
Inventor: OOKUMA YOUICHIROU
IPC: B01D46/00
Filed: 1978-06-01
Abstract: PURPOSE: To improve dust collecting efficiency of a dust collector by combining a vacuum suction unit which has lower flow rate and higher static pressure than the dust collector.  
     CONSTITUTION: Dust 5 is sucked and transferred to an inlet 2 of a dust collector 1 by a blower 7 which consits of a fan, motor, and casings; thereafter, it is sucked and filtered by the dust collector 1. As suction characteristic of the blower 7 is a static pressure type as shown in curve B, the blower can stand high flow-resistance. Therefore, even if a duct 4 is long and narrow, or the opening area of a hood 3 is small, the dust is easily sucked and transferred. In addition, a dust collector with small capacity is enough because it is required to suck only the dust being transferred near the inlet 2 of the dust collector 1.
