Title: High-frequency transmitter and its production
Inventor: FUJITA MITSUHIRO
IPC: H05H1/46
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To obtain the subject transmitter consisting of an aluminum nitride sintered compact predominant in aluminum nitride crystal phase, specified in silicon content and dielectric loss, thereby improved in high-frequency transmission and prevented from breakage due to heat shock caused by high-frequency energy absorption. SOLUTION: This high-frequency transmitter is such one as to be <=200 ppm in silicon content and <=1×10-2 in dielectric loss (tanδ). The transmitter is obtained, for example, by pressure burning of aluminum nitride powder at 1,600-2,000 deg.C in a nonoxidative atmosphere to form an aluminum nitride sintered compact, wherein the silicon content of the aluminum nitride powder is brought to <=300 ppm and the silicon content of the final transmitter to <=200 ppm by volatilizing an excess of the silicon during burning process. If this transmitter contains a rare earth metal oxide phase, its content is pref. <=10 wt.%, on an outer basis, based on the aluminum nitride crystal phase.

Abstract: PURPOSE:To prevent the occurrence of leakage at the time of connecting a hose without requiring a deburring process, or improving mold precision by applying the constitution where a mounted section with a hose connected to the external side thereof is formed out of an end shaft section, a tapered bulge section gradually increased in diameter toward a base end, and a base end shaft section respectively in order from an end. CONSTITUTION:A hose joint 10 has a mounted section 14 linearly projected from a body 12 for connecting a hose to the external side thereof. In this case, the section 14 is formed out of an end shaft section 16, a tapered bulge section 18, and a base end shaft section 20 having the same diameter as the end shaft section 16, respectively in order from a forward end to a base end. The tapered bulge section 18 is formed to have a taper with diameter gradually increased toward the base end. A passage 22 is formed through the section 14 and the body 12 along the center line of the section 14. This hose joint 10 forms the external surface of the body 12 and the base end shaft section 20 with a split mold, while the external surface of the section 18, the edge of the section 16 and the passage 22 are formed with a trimming die laid adjacent to the split mold. As a result, forming can be made without any bur at the end shaft section 16, and a gap with a hose due to a bur at the time of connection can be eliminated to prevent leakage.

Title: Recorder
Inventor: MURAYAMA TOMIO
IPC: H04N1/29
Filed: 1980-10-31
Abstract: PURPOSE:To realize recording and reproduction with fidelity, by performing a reproduction sampling with suficiently higher frequency than a recording sampling  clock corresponding to a recording head. CONSTITUTION:The frequency of a reproducted sampling signal (f) is sufficiently  higher than that of a recorded sampling signal (d) frequency-divided with a  frequency- divider 6. When a transmission signal (c) and a signal (f) are inputted,  the output of a D latch circuit 1 is applied to a counter 2, which counts the signal (f) when an output (g) is at H level. Every time when the signal (d) is produced, the  count value of the counter 2 is transmitted to the latch circuit 3. Thus, the number  of times of a sampling value 1 by the signal (f) at one period of the signal (d) is  stored in the circuit 3. The storage value of the circuit 3 is compared with the set  value of a discrimination and reference set circuit 11 at a comparator 4. The output  of the comparator 4 is transmitted to a D latch circuit 5, where an output is made  every production timing of the signal (d) to form a reproducing waveform.

Title: Magnetic disk device
Inventor: YONEMITSU SHINOBU
IPC: G06F21/62
Filed: 1989-06-15
Abstract: PURPOSE:To make unfair read of data on a medium impossible and to keep the secrecy of data by turning the recorded data on an attachable/detachable rigid medium into the ciphered data. CONSTITUTION:The normal sentence write data printed to an interface circuit 1 is transmitted to a ciphering circuit 2. The circuit 2 ciphers the received write data and sends it to a read/write amplifier circuit 4. The circuit 4 amplifies the ciphered read data and supplies it to a read/write head 5. The head 5 writes the amplified write data into an attachable/detachable rigid medium. In a read state, the ciphered data is turned into the normal sentence by a normal sentence production circuit 3 and sent to the circuit 1. Thus the recorded data on the rigid medium can be turned into the ciphered data even though the data transferred between the circuit 1 and an external device are written in the normal sentences. As a result, the secrecy of data can be secured.

Title: Electronic component and junction structure
Inventor: YAMAMOTO MICHIHIKO
IPC: H01L21/321
Filed: 1990-06-13
Abstract: PURPOSE:To join electronic components for both hard and soft conducting layers by laminating both said conducting layers alternately and forming a junction section which projects outside. CONSTITUTION:A pad electrode 11 is installed on the top of an IC chip 10 while an insulation layer 12, which excludes the electrode 11, is also installed. A conjunction section 13 is formed on the electrode 11. The conjunction section 13 is formed under multi-layer structure where hard conducting layers ranging from 14 to 17 and soft conducting layers ranging from 18 to 21 are alternately laminated. The respective layers 18 to 19 are subjected to deformation, responding to the difference between each displacement and absorbs the difference of displacement between the chip 10 and a substrate 22. As a result, even if the layers 14 to 17 are not subjected to deformation, there occurs a crack on the junction section 13, but the junction layer 13 is protected from breakdown. It is also possible to join both the chip 10 and the substrate 22 definitely.

Title: Follow-up traveling controller
Inventor: SASAKI KAZUYA
IPC: B60W30/00
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To dispense with the setup of a switch to indicate the start and release of follow-up traveling control, reducing a burden on a driver by indicating the start and release of this follow-up traveling control due to a shift lever position of an automatic transmission. SOLUTION: This controller is provided with a shift lever position detecting means M2 detecting a shift lever position of an automatic transmission, a spart indicating means M3 indicating the start of the follow-up traveling control in the case where the shift lever position detected by the shift lever position detecting means is low or second where it comes to less than the specified transmission gear ratio, and a releasing means M4 releasing the follow-up traveling control in the case where the shift lever position turning to the higher transmission gear ratio than the specified gear ratio is detected by the shift lever position detecting means, respectively. Therefore, a new switch to indicate the start and release falls into disuse, so the start and release of this control can be done by the shift lever operation of a driver without imparting a sense of incompatibility, and thus a burden on the driver will in no case be increased at all.
