Title: Hermetic seal liquid active material battery
Inventor: WATANABE OSAMU
IPC: H01M50/528
Filed: 1992-08-19
Abstract: PURPOSE:To perform properly explosion-proof function by tearing destruction of a thin-walled portion, thereby raising operation reliability of same function by disposing a resin annular body on the inner surface of the bottom of a battery vessel having an explosion-proof thin-walled portion on its bottom. CONSTITUTION:An explosion-proof thin-walled portion 4a in crisscross form is provided by forming grooves 3 of same form in a protruding portion 2a of the bottom 2 of a battery vessel 1. A resin annular body 5 of ethylene- ethylene terafluoride resin is disposed on the inner surface of the bottom 2. Thickness of the annular body 5 is preferably 0.2mm or more when working property at the time of insertion into the vessel 1, for example, is considered. However, on the other hand, with increase in thickness of the annular body 5, filling quantity of active material, etc., decreases; the thickness is thus normally about 1mm or smaller. Accordingly, even when lithium is partly melted in tearing of the thin-walled portion 4, jetting of molten lithium is prevented by the annular body 5, so that the explosion-proof function is properly operated. Then, when lead wire is welded to the vessel 1, the welding heat is not directly applied to lithium due to the annular body 5, thereby securing the safety.

Title: Pwm/pam-control type motor controller and method for controlling air conditioner and motor using the same
Inventor: NOTOHARA YASUO
IPC: H02P21/04
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a motor control means which is provided with a commutating phase control means which changes the commutating timing of the winding of a motor and can always operate the motor highly efficiently over a wide operating range, by changing the commutating phase of the winding of the motor in accordance with the speed and load of the motor. SOLUTION: Whether PAM control or commutating phase control is being made is discriminated (Sh). When the commutating phase control is made, whether the speed deviation calculated through processing (Sb) is positive or negative is discriminated (Si). When the speed deviation is positive, namely, a speed increase is required ('Yes' in Si), a commutating position command is reduced by a certain preset value (Sj). When the speed deviation is negative, namely, a speed decrease is required ('No' in Si), on the contrary, the commutating phase command is increased by a certain preset value (Sk). Since the commutating phase command has the value used for calculating the delay time until a drive signal is actually changed from the changing point of a position detecting signal, the phase advances as the command becomes smaller.  In other words, the more the value of the commutating phase command becomes smaller, the more the speed increases.

Title: Packaging means for motor or the like
Inventor: KATAOKA HACHIRO
IPC: B65D81/02
Filed: 1990-09-13
Abstract: PURPOSE:To contrive the packaging of each item individually in a simple, rapid and compact manner by a method wherein, after inserting a locking piece completely into a locking hole and the locking piece is strongly pushed down to resiliently deform an arcuate projecting part under the locking piece. CONSTITUTION:After blank board A is folded to engage its side edge 1 with the opposite side edge 2, a nearly T-shaped locking piece 4 is inserted into a locking hole 3 as far as it will go while bending both the end parts toward each other with overlapping pieces 5 and 5 extending along the underside of a first folding face A1. In this condition, since an arcuate projecting part 3a is made to underlie the locking piece 4, the locking piece 4 is strongly pushed down to resiliently force down the arcuate projecting part 3a provided at the edge of the locking hole 3, the locking piece 4 is passed under the arcuate projecting part 3a and the arcuate part 3a overlies the locking piece 4. For this reason, the T-shaped locking piece 4 and the arcuate projecting part 39 forms so strong an interlocking joint as to withstand the weight of a motor M.

Title: Duplicated feed detecting device and duplicated feed detecting method
Inventor: OKADA SHINYA
IPC: B65H7/14
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To reduce the mistake frequency of duplicated feed detection by detecting a duplicated feed based on the comparison result of data in the ranges of a plurality of samples at different places in the conveying direction of paper sheets. SOLUTION: When a paper sheet 2 passes through a duplicated feed sensor 10 (between an emitted light sensor 10a and a received light sensor 10b), sample ranges are set at a plurality of different places along the conveying direction, and the average value of the light transmission quantity is determined for the predetermined number of samples in the sample ranges. A reference value for detecting a duplicated feed when the first paper sheet 2 is conveyed is determined for the samples from the average value in the sample ranges. When the second and subsequent paper sheets 2 are conveyed, the average value of the sample values in the sample ranges is compared with the reference value determined for the same sample ranges to detect a duplicated feed.  The overall duplicated feed detection is made based on the duplicated feed detection results for the sample ranges, therefore high-reliability duplicated feed detection can be made even if the paper sheet 2 is loosened or soars.

Abstract: PURPOSE:To inexpensively and speedily produce a sliding member having excellent wear resistance and high long-term reliability by subjecting the sliding part of Al or Al alloy to a rapid melting and rapid resolidifying treatment with a high density energy and providing numerous pores on the surface layer. CONSTITUTION:The sliding part of the Al alloy 6 of an Al-Si system, etc., where the above-mentioned Al alloys slide with each other or the Al alloy and cast iron, etc., slide each other is irradiated with a laser 8 of high density energy and is thereby subjected to the rapid melting and rapid resolidifying treatment.

Title: Apparatus for discovering water leak point

Filed: 1986-10-15
Abstract: PURPOSE:To mechanically estimate the pipe extension of a water pipe from a sound collection point to a water leake point, by measuring the power of the entire frequency band component of a water leak sound and that of the low frequency band component thereof. CONSTITUTION:A water leak sound is collected by a mounted pickup 1 and a power measuring part 2 outputs the power signal P of the entire frequency band component of a water leak sound signal 7. A low-pass filter 3 extracts the low frequency band signal 8 containing only the low frequency band component of the water leak sound from the water leak sound signal 7 and a power measuring part 4 outputs the power signal PL of the low frequency band component of the water leak sound. Since both of a sound pressure level and a low band power ratio have the correlation with pipe extension (d), a pipe extension estimation part 6 estimates the pipe extension of a water pipe from the sound collection point to the water leak point from the values of the sound pressure level and the low band power ratio to display the same on a pipe extension display part 6.
