Abstract: PROBLEM TO BE SOLVED: To provide navigation equipment capable of reducing the time necessary to reach a destination by a method wherein a user enters a congested road without any superfluous time. SOLUTION: A route retrieving part 105 performs route retrieval as far as a destination by referring to information on a destination, desired arrival time, etc., which are inputted by an operation part 102 such as a touch panel and buttons and map information which can be led out of a map information storing part such as a CD-ROM and a DVD-ROM. A route guiding part 103 displays the route guidance on a display part 101 on the basis of a retrieved route, a present position obtained by a present position measuring part 106 of a GPS receiver or the like, map information on the present position periphery which can be obtained from a map information storing part 104, and a retrieved route.  When a congested road entering point detecting part 107 detects an entering point into a congested road by turning right, from a route retrieved by the route retrieval part 105 and congestion information on the route which is obtained from a congestion information obtaining part 108, a congested road entering route re-retrieval part 109 retrieves again a route which evades the entering by turning right into a detected point, and performs route guidance.

Title: Manufacture of al heat exchanger
Inventor: TOMA KEN
IPC: B23K1/00
Filed: 1987-06-12
Abstract: PURPOSE:To lighten a product by forming a tube and fin by the Al alloy contg. Mn and Si at specified wt.% and also cooling the specified temp. range from a brazing temp. at specified cooling speed. CONSTITUTION:The tube and fin of an Al heat exchanger are composed by the Al alloy contg. 0.1-1.5% Mn, 0.1-1.5% Si in wt.% to execute heated brazing. In this case, the temp. range from brazing temp. to 350 deg.C is cooled at the cooling speed of 100-1000 deg.C/min after brazing. The Al alloy stock contg. a proper amt. of Mn and Si is increased at its strength by the uniform dispersion of a fine precipitate and solid solution of Mn. A high temp. strength is also obtd. because the cooling speed is high in the range from brazing temp. to 350 deg.C. The heat exchanger is thus lightened as the heat exchanger material can be thinned strengthwise.

Title: Semiconductor device and manufacture thereof
Inventor: KUROKAWA ATSUSHI
IPC: H01L21/338
Filed: 1986-06-25
Abstract: PURPOSE:To improve reliability of circuit elements, by providing an insulation layer the upper portion of which is formed of phosphosilicate glass (PSG), directly on a compound semiconductor substrate. CONSTITUTION:A channel 2 of an n-tupe region is formed in a GaAs substrate 1. A source 3 and a drain 4 of n<+> region are formed on the opposite sides of the channel 2 in contact therewith. A Schottky electrode 5 of tungsten silicide (WSix) is deposited on the surface region of the substrate where the channel 2 is present. A first insulation layer 6 of PSG is formed on the Schottky electrode 5 and the surface of the substrate. Since PSG has a function of effectively trapping metal ions, paticularly those metal ions having high ionizing properties, undesirable metal ions such as sodium or magnecium ions can be thereby prevented from entering into the compound semiconductor substrate. In this manner, it is possible to prevent variance in electric characteristics of circuit elements due to effects of ions.

Title: Gas alarm device
Inventor: SUZUKI TOSHIHARU
IPC: G08B17/117
Filed: 1977-12-08
Abstract: PURPOSE: To indicate plural alarm displays, by generating electric signals by using gas sensor of which property changes when coming in contact with gas, and operating the alarm display device through signal distributor.  
     CONSTITUTION: For instance, nickel-chrome heating body layer 2, tin oxide layer 3 containing a trace of Pd, and metallic electrode films 4, 4 are formed on a glass substrate 1 measuring about 4 × 4 mm to obtain a sensor element. While keeping this element at about 300°C, when it is brought into contact with reducing gas such as LP gas, the resistance of the tin oxide layer 3, which is a detecting film, changes due to the gas concentration, and an electric signal corresponding to such change in the resistance is taken out from the electrode 4. And the signal is fed into a signal distributor which divides the setting of the alarm level, thereby operating respective alarms. For instance, when three kinds of buzzers are used, a signal  sound of 4000 Hz is sounded when the concentration is more than 2.2% (within the  explosive limit), 2000 Hz when the concentration is within 0.2 to 0.3% (critical range), and 500 Hz when the concentration is within 0.05%.
