Title: Production of metal-ceramics composite
Inventor: NAITO KAZUNARI
IPC: B22D19/00
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To solve the problem of a liability to formation of shrinkage cavity, which is a problem of an Si-containing Al-Si-Mg type aluminum alloy used in the case where heat resistance is required or an SiC powder is used as a reinforcement. SOLUTION: This metal-ceramics composite can be produced by forming a preform by use of ceramic fibers or grains as a reinforcement and allowing a metal as a base material to penetrate into the preform. At this time, the metal is allowed to penetrate by using an aluminum alloy casting of class 8A (symbol: AC8A, JIS H5202) as the metal and allowing the metal to penetrate into the preform under no pressure or further performing heating treatment and age hardening treatment after the penetration of the metal.

Title: Map display apparatus for aircraft
Inventor: FUNAOKA KAZUAKI
IPC: G08G5/04
Filed: 1993-12-28
Abstract: PURPOSE:To improve safety against terrain obstacles present on a flying route by correcting the altitude information and the position information of own aircraft in flying, enhancing the position measuring accuracy, and determining the safe altitude of the flying route interactively. CONSTITUTION:The measured value of a GPS receiver 1 is not used as the altitude information of own aircraft, but a barometric altimeter undergoes QNH correction with an altitude information correcting means (a), and the altitude value corrected for external temperature is used. The highly accurate altitude information is sent into a danger-alarm-range operator 2 and a display controller 6. As the position of own aircraft, the value of an own-aircraft-position correcting means (b), which is obtained by multiplying the ground speed and the turning rate of the GPS 1 by the operating time, is used. The corrected position of own aircraft is sent into the operator 2 and the controller 6, and the position of the aircraft when the position measurement is finished is displayed 7. When the ground speed reaches the specified value or more, the altitude alarm is automatically operated with a GS switch (c). Furthermore, a flying-route/safe-altitude confirming means (d) is provided, and the flying route is registered, and the safe altitude is inquired. Thus, the safety is checked interactively.

Title: Method for printing by line thermal head
Inventor: SOGABE MASUO
IPC: B65B61/02
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To average power supply and extend a pulse life of a thermal head by changing positions of dots of a line thermal head to which the power is supplied, for every predetermined number of printing times and preventing the power supply from being concentrated to a certain dot. SOLUTION: When printing contents are loaded to a memory, printing of one product part or part corresponding to a plurality of products is carried out with data transferred to a line thermal head depending on whether F is 0 or 1. The printing of one product or a plurality of products is performed while the data shifted by specific dots are transferred. Accordingly, objects to be printed are printed sequentially at positions shifted by a predetermined amount for every printing point. The power supply is prevented from being concentrated to specific dots and averaged in the line thermal head. Since dots of the line thermal head are turned conductive averagely, a pulse life of the line thermal head is extended.
