Title: Power source controller
Inventor: NINOMIYA RYOJI
IPC: G06F1/26
Filed: 1990-09-13
Abstract: PURPOSE:To lengthen the driving time of a battery, and also, to improve the port-ability by supplying power required for driving a system from one piece of battery from plural batteries, and also, checking whether its battery is a low one or not, and supplying the power from the other battery, when the low one is detected. CONSTITUTION:Power is supplied to a system from a battery in which FETs 12,22 are turned on, of plural pieces of batteries 11,21. A power source controller 17 controls the FETs 12,22,14 and 24, and selects the battery for supplying a current to the system. Also, whether the battery is a low one or not is decided from the relation of a battery voltage and the current, and a function for switching the battery for supplying the power in the case of a low battery is also provided. In such a way, since plural pieces of batteries are used in order, the battery driving time can be lengthened, and the capacity per one piece of battery can be reduced. Moreover, in the case the battery comes to a low one, one piece each becomes a low battery in order, therefore, in the case of carrying an auxiliary battery, it will suffice that at least only one piece is carried, then the port-ability is made excellent.

Abstract: PURPOSE:To prevent the effect of moisture by inserting a sample and a cantilever having a probe into the vacuum at a specified vacuum degree, and observing the surface. CONSTITUTION:A cantilever 2 having a probe is fixed to a fine-adjustment moving mechanism 3 and detects the force from the surface of a sample 10. A laser beam 9 is emitted from a semiconductor laser 4, which is fixed to a fine adjustment mechanism 5. The laser beam is reflected from the rear surface of the lever 2, and the deflected amount of the beam is measured with a semiconductor position sensor 6. A fine adjustment mechanism 7 adjusts the position of the sensor 6. These mechanisms are fixed to a detector base 8. The mechanism system provided in a vacuum cell 1 is taken out into atmosphere. The sample 10 is stuck to a scanner 11. Then, the tip of the probe is set with a height adjusting mechanism 14 and a moving mechanism 12 so that the tip of the probe comes to the intended observing position. The mechanism system is inserted into the vacuum cell 1, and the vacuum degree is maintained at 1X10<-5>Torr or less. Under this state, the sample 10 undergoes raster movement, and the image of the irregularities of the surface is obtained. Thus, the probe and the sample 10 are not affected by moisture and the like, and the surface can be accurately measured.

Title: Non-water filled-up electromagnetic flowmeter
Inventor: YOSHIDA YUTAKA
IPC: G01F1/60
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that a conventional non-water filled-up electromagnetic flow meter can not find an accurate flow rate of a fluid to be measured due to an OB/OA curve becoming a double-valued function when the flow rate is small while the flowmeter correctly measures the flow rate before the flow rate becomes such small flow rate. SOLUTION: The ratio OB/OA of the flow rate signal output OA of an electrode 22 when an upper side exciting coil CA is excited to the flow rate signal output OB of the electrode 22 when a lower side exciting coil CB is excited is found. Since the width WB of the lower exciting coil CB is narrower than that WA of the upper exciting coil CA, the ratio of the magnetic flux density of the coil CB to that of the coil CA becomes larger as the water level becomes lower. Therefore, the OB/OA ratio is maintained at a single-value function and the accurate flow rate of the water can be found even when the flow rate becomes small as shown in Fig. (b).

Title: Semiconductor memory
Inventor: WATANABE TAKESHI
IPC: H01L29/792
Filed: 1988-09-27
Abstract: PURPOSE:To reduce the degree of increase of power supply currents di/dt and to suppress the fluctuation of standard voltage wiring on a semiconductor substrate by providing a transistor between an output terminal and a power supply, and providing a circuit which delays only when this gate voltage changes from a high level to a low level. CONSTITUTION:By B7 becoming a low level P7 becomes ON and N7 becomes OFF, and output 07 discharges electricity from a low level to a high level. The charge currents at this time becomes half as gm of P7 is set to half the conventional one, and di/dt also becomes 1/2. Pb7 is off until F7 becomes a low level, and the difference of time for B7 and F7 to become low levels is determined by the switching speeds of IA7 of IB7 and can be set easily. When Pb7 becomes on at which F7 becomes a low level, the di/dt of P7 is rapidly nearing to 0, and even if Pb7 is turned ON and di/dt becomes great, the total di/dt becomes half the conventional one. This way, by making di/dt small, the fluctuation of VCC-r becomes small, and malfunction becomes hard to occur.

Title: Production of thermal head
Inventor: SHIRAKAWA KYOJI
IPC: B41J2/335
Filed: 1985-10-29
Abstract: PURPOSE:To enable printing with high printed density to be performed with low electric power, by a method wherein Al is vapor-deposited on a protective layer, is replaced by Zn, and an electrolessly plated Ni layer provided on the Zn layer thus formed is selectively provided in a desired shape at a desired part by photolithography. CONSTITUTION:Under the condition where a terminal part of a thermal head is masked, a thin film of Al or an Al alloy is provided on a protective layer 6 in a thickness of 1-2mum by a sputtering or vacuum deposition machine. After the thin Al film is etched away by an etching liquid and replaced by Zn, the body is immersed in an electroless Ni plating liquid, whereby Ni is deposited to form a plated Ni layer 7. It is most effective that an electroless Ni plate forming liquid (e.g., a commercially available Bondal liquid) for Al is used as the etching liquid to sufficiently remove the thin Al film on the protective layer 6 by etching. The Ni layer 7 thus provided has a high thermal conductivity and relatively good abrasion resistance, so that the useful life of the head is prolonged, transfer efficiency is favorable even with low electric power, and printing with high printing quality can be performed.
