Title: Automobile cooler using absorption refrigerator
Inventor: KASHIMA TAKAMITSU
IPC: B60H1/32
Filed: 2001-02-08
Abstract: PROBLEM TO BE SOLVED: To cool a cabin effectively even during outdoor parking or standing under the blazing sun. SOLUTION: When an automobile 50 is parked or left standing in a condition at high outside air temperature, for example, under the blazing sun, its body is heated to transfer heat to a generator 2 arranged in a trunk 51, and the generator 2 is heated accordingly. An ammonia solution in the generator 2 then forms bubbles, and an air-lift pump 3 delivers them to a separator 4, which in turn provides gas/liquid separation by which an ammonia dilution is delivered to an absorber 7 and separated ammonia gas is delivered to a condenser 5. The condenser 5 cools the ammonia gas into a condensed and liquefied phase, which enters an evaporator 6 wherein it vaporizes and deprives the ambience of heat of vaporization to cool the cabin.  Even during outdoor parking or standing under the blazing sun, the cabin can be effectively cooled against the high- temperature outside to eliminate a feeling of discomfort of an occupant who is getting into the standing vehicle.

Title: Ice dispenser
Inventor: NAGIRA MASANOBU
IPC: F25C5/18
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent ice from being made needlessly. SOLUTION: When ice is full, and a detection plate 60 rises to a predetermined height to turn a detection switch 66 (T1 ) off, a compressor 18 and a motor 26 of an auger 23 are interrupted in this order to stop ice making. Simultaneously, a timer 71 is started with a switch invalid means 72, and the invalid is continued for a predetermined time thereafter even if the detection plate 60 lowers until the detection switch 66 switched on, ice making is prevented from being restarted needlessly. During this time once a discharge switch 75 is operated (T4 ), the timer 71 is reset with a switch restoration means 73 and hence a detection function of the detection switch 66 is made valid. Hereby, when the amount of stored ice is reduced and hence the detection switch 66 is switched on, the ice making is restarted the compressor 18, and the motor 26 actuated in this order.  The restarting of the ice making is performed only when it is truly needed to improve reliability and prevent electric power from being wastefully consumed.

Title: Bipolar transistor
Inventor: MATSUNO NORIO
IPC: H01L29/10
Filed: 2001-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a bipolar transistor which can obtain high characteristics equal to a composition inclined base transistor, is superior in yield and uniformity, and has high productivity. SOLUTION: A base is constituted of a region 1 having low Ge concentration and an area 2 with high concentration. For forming a base layer, a film-forming condition on two types of Ge concentrations can be grasped, and the man-hours for film forming condition setting becomes smaller than in the conventional technology. Since the number of switching times on Ge composition at the time of forming the film is required to be only one, a system is less likely to be influenced by a state in which a growth condition moves. Then, the Ge concentration is kept constant, and a comparatively thick film is formed. Thus, the film can more stably be formed. Consequently, uniformity, yield and productivity of the device are improved. Even if the number of steps on Ge composition is reduced, the peak value of fT and fmax is equal to the composition inclined base transistor.
