Title: Electric water heater
Inventor: NAKAO YOSHITADA
IPC: A47J27/00
Filed: 1988-11-30
Abstract: PURPOSE:To surely detect the presence of water in a container without lowering the accuracy of detection of boiling by providing a means for detecting no-load heating in accordance with a counted time necessary for increasing the temperature of a heat sensing element up to a specific value, in addition to a unit temperature gradient computing means, and further by providing a heating stop means. CONSTITUTION:There are provided a unit temperature gradient computing means 11 for computing a unit temperature gradient successively each time when a temperature detected by a thermistor 9 increases by an unit value, and a means 12 for temporarily storing an output from the computing means 11. Further, there are provided a boiling detecting means 13 for comparing thus stored gradient with a gradient which varies sometimes, from a unit temperature gradient computing means 11, and a no-load heating detecting means 14 for counting a time required for increasing a temperature detected by the thermistor from a first set temperature to a second set temperature so as to compare the count time with a predetermined value. Further, there is provided a means for stopping the energization of a heater in accordance with an output from the boiling detecting means 13 or the no-load detecting means 14. With this arrangement, the first and second set temperatures are set independently from each other, and if the difference between both temperatures can be set to a value which is greater than fluctuations in a temperature curve just after heating and water addition, it is possible to surely detect the presence of water without erroneously stopping the heating.

Title: Power-saving ac adapter
Inventor: FUJIWARA GENICHI
IPC: H02J7/02
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To reduce the wasteful use of electric power due to unwitting turn-off of an AC adapter, etc., by providing the AC adapter which charges a battery by converting AC power into prescribed DC power, and cutting off the supply of AC power to the adapter when the charging of the battery is completed by monitoring the charging state. SOLUTION: When the charging of a battery 62 is completed, a charging-state detecting section 33 discriminates a charging completing state from the level of a charging signal and turns off a relay 32. Consequently, the power supply from a connector 11 is cut off. The detecting section 33 uses the DC power VD from an AC adapter 20 as its motive power, but, when the charging of the battery 62 is completed, the supply of the DC power VD to the charging state detecting section 33 is cut off by turning off the relay 32 so as to save the power consumption by the adapter 20.  Therefore, the power consumption of the adapter 20 can be saved surely even when it is forgotten that the battery 62 is being charged even when the charging is completed or the completion of charging is not noticed, because the supply of the AC power to the detecting section 33 is cut off when the charging of the battery 62 is completed.

Inventor: YAMANAKA NAOKI
IPC: E04B1/61
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the occurrence of cracking near coupling fittings because a buffering member can be tightly adhered to both of a jointing surface of a prefabricated member and the front plate of the coupling fittings and thus the occurrence of a gap between the front plate and the jointing surface can be prevented and therefore a tensile force to the coupling fittings does not act to a main body even when the coupling member is tightened.

Title: Divided chamber type diesel engine
Inventor: KASHIMOTO MASAAKI
IPC: F02B19/08
Filed: 1987-11-30
Abstract: PURPOSE:To damp a pressure wave in a nozzle hole as well as to make a knock sound preventable from occurring by installing a baggy displacement chamber in and around a combustion chamber, and interconnecting it to the point midway in the nozzle hole. CONSTITUTION:In a divided chamber type diesel engine Z, a baggy displacement part 9 with proper volume is formed in and around a divided chamber 6, while this displacement part 9 and the midway of a nozzle hole 7 are interconnected to each other with an oblique holelike interconnecting passage 10. Volumetric capacity in this displacement part 9, length of the interconnecting passage 10 and its sectional area are properly set, whereby a part of a high level pressure wave produced in the nozzle hole 7 is reached to the displacement part 9 by way of the interconnecting passage 10, and when it is reversed hereat and transmitted to the nozzle hole again, this reversed pressure wave interferes with the high level pressure wave inside the nozzle hole 7 each other and thereby it works so as to damp this high level pressure wave. Consequently, the pressure wave being produced inside the nozzle hole 7 is damped as small as possible, so that a knock sound attributable to this pressure wave comes to be effectively reduced as much as a portion for that.

Abstract: PURPOSE:To improve the breakdown voltage characteristics between the third and the first Si layers by a method wherein the first and the second Si layers are isolated by an insulating layer to narrow the depletion layer extending over the second layer affected by the first layer so that the second layer may be thinned to set up almost equivalent potentials in the third and the first Si layers. CONSTITUTION:An SiO2 film 11 on a P type Si substrate 12 and another SiO2 13 on an N type Si substrate 14 are brought into contact with each other and then heat treated to bond both substrates 12, 14 with each other. Then, the N type substrate 14 lapped and etched for thinning process is reactive ion-etched to make an opening 16. First, overall surface is covered with an SiO2 17 to be isolated taking the shape of an island. Second, the SiO2 17 is selectively removed and thermal oxidized to form a gate insulating film 18 and then a doped poly Si gate electrode 19 is provided on a gate oxide film 18A. Third, the island part implanted with B ion using a mask covering another oxide film 18B is heat treated to form a P type back gate 20 reaching another SiO2 15 and after removing the mask, the gate 20 implanted with As ions is annealed to form an N<+>source layer 21 and N<+>drain layer 22. Finally, after depositing the other SiO2 23 and performing the gettering process, openings 24, 25 are made respectively to form Al electrodes 26, 27. Through these procedures, the substrate 12 and the back gate 20 can be biased at equipotential to improve the breakdown voltage characteristics between the substrate 12 and the back gate 20.

Title: Information storing/reproducing device
Inventor: IKEDA HIDETOSHI
IPC: G11B7/126
Filed: 1986-12-20
Abstract: PURPOSE:To evade deterioration of a light source and to attain the even record states at each record position by changing the bias electric power not the peak electric power of the light source at each record position in the radius direction of a recording medium. CONSTITUTION:When the information is recorded on an optical disk 1, a movable contact pieces S0 of a switch circuit SW is set at either one of fixed contacts S5-S2 by a CPU23. In this case, the bias electric power is increased toward the outer circumference of the disk 1. When a record signal is supplied from a laser control circuit 14, transistors TR1 and TR2 work to actuate a semiconductor laser 9. Thus a recording state is set. In this case, a TR3 changes the base potential of the TR2 based on the level of a bias current so that the peak value of the record signal has no change despite the switch of the bias electric power.
