Filed: 1990-08-13
Abstract: PURPOSE:To simply support a guide rail without the influence of the arrangement of shelves by attaching a guide rail to the upper side of a pillar for the shelf, and extendingly providing the upper frame of a crane along the guide rail. CONSTITUTION:A guide rail 24 is attached to the upper side of a pillar 20 with supporting bolts or the like, and the one end of the projecting part of the guide rail 24 is supported by a supporting member 22 fixed to the pillar 20 of a shelf 10.

Title: Data registration device
Inventor: WATANABE TSUNEHIRO
IPC: G06F21/62
Filed: 1989-08-22
Abstract: PURPOSE:To make operation easy and secure and to prevent registered data from being destroyed owing to the runaway of a CPU by writing the data in a memory with the output of a signal output means which writes data in the memory only for a specific time. CONSTITUTION:When the set key of an operation part 5 is pressed to make contacts 7 and 8 of a two-circuit ON switch, transfer and writing from a RAM a3 to a RAM b4 becomes possible only for the time determined by the time constant circuit consisting of a resistor 9 and a capacitor 10. Further, when a signal 11 outputted by the time constant circuit turns into an H signal again after the transfer from the RAM a3 to the RAM b4, the output 14 of an OR gate 13 is an H signal without reference to whether a write signal 12 from a CPU 1 is an H or L signal, so the writing to the RAM b4 is inhibited. Consequently, the operation of a data register becomes easy and secure and a registration switch is omitted, so the CPU is prevented from running away when the registration switch is left ON forgetfully, thereby securely protecting the registered data.

Title: Operation frequency controller of air conditioner
Inventor: KOBAYASHI ATSUSHI
IPC: F25B49/02
Filed: 1984-10-12
Abstract: PURPOSE:To make it possible to correct the operation frequency by providing load detecting means, frequency memory means, frequency discriminating means, output means, drive means and further frequency correcting means increasing or decreasing the operation frequency to a corrected value. CONSTITUTION:An air conditioning load is detected by a load detector 1, and a signal is inputted to an LSI2. In a case where a seventh memory part is selected by frequency discriminating means, the operation frequency of 70Hz stored in the 7th memory part of frequency memory means is read out, and the 7th memory part corresponds to an input port 11, and hence carries out an action to read out an input voltage VH of the input port 11 because the 7th memory part corresponds to the input port 11. The input voltage VH to the input port 11 is controlled by a frequency correction circuit 5. The LSI2 A/D converts the input voltage VH to the input port 11, and outputs O-M bits. The corrected value corresponding to each bit is stored in frequency storing means of the LSI2, and corrected values corresponding to bits are determined. Thus, a correction is added to the operation frequency and the corrected operation frequency is outputted.

SOLUTION: This polarizing plate 1 is constituted by holding and laminating substrate base materials 1B for which TAC films are adopted on the front and rear surfaces of a polishing element 1A and is disposed on the front surface side to be visibly admitted of a liquid crystal display. The TAC film is not used for the surface base material 1B laminated on the front surface side to be visibly admitted of the polarizing plate 1 opposite to the liquid crystal display side and the transparent thin film layer 2A having the refractive index lower than the refractive index of the base material for forming is formed on the surface in place of the TAC film.  At this time, the tight adhesion property of the transparent thin film layer 2A is better than the tight adhesion of the TAC and a transparent urethane film which does not hinder the polarization function of the polishing element 1a is used as the surface base material 1B.

Title: Washing machine
Inventor: NAKAMURA SATORU
IPC: D06F33/02
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To provide a washing machine whose washing time is shortened. SOLUTION: With the opening of a feed valve, a pump to feed bathtub water starts driving to realize parallel feeding of both city water and the bathtub water (Step T1). In the step T6 for the intermediate dehydration, the power supply to the motor is carried out intermittently until power supply to the motor is shut down when rotational frequencies of a spinning tub and a pulsator get to specified ones. In other words, in this step for the intermediate dehydration, only so called intermittent dehydration is carried out instead of conventional continuous one. This means that the times of both feeding water and intermediate dehydration are shortened than those using conventional washing machine.

Abstract: PURPOSE:To shorten the waiting time of a user and to improve the efficiency of a copying operation by setting a start-up time after applying a power source or a start-up time after releasing a standby mode the shortest in accordance with a copying mode. CONSTITUTION:At the start-up time of a fixing means, the start-up temperatures T1 and T2 of the fixing means 11 at which it is possible to transmit a copying start command are set to be a specified temperature which the means 11 should attain after a time that is from commanding the start of copying until a transfer paper reaches the means 11 in the copying mode for every copying mode. Therefore, the means 11 just rises to a fixing temperature T when the leading edge of the transfer paper reaches the means 11 even though a necessary time from commanding the start of copying until the leading edge of the transfer paper reaches the means 11 is different in every copying mode. Thus, the waiting time is made minimum in every copying mode and heat efficiency is improved.

Title: Method and device for detecting corrosion, crack, etc., of steel material
Inventor: KIKUCHI HIDEAKI
IPC: G01N27/83
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To accurately discriminate corrosion, crack, etc., on the inside surface of a steel pipe using magnetism, without depending on worker's intuition, etc. SOLUTION: Excitation coils 12a and 12b are wound at two separate positions of a steel pipe 10, while a transmission magnetic flux density detecting coil 14 wound at their intermediate point. The two excitation coils 12a and 12b are so magnetized that their orientations are opposite each other while the transmission magnetic flux densities are the same magnetic flux in the steel pipe 10. The two excitation coils 12a and 12b and the transmission magnetic flux density detecting coil 14 are fixed in relative position, while allowed to move relatively in axis direction to the steel pipe 10. When changes occur in magnetic reluctance due to corrosion, crack, etc., on the steel pipe 10.  The detection voltage from the transmission magnetic flux density detecting coil 14 becomes higher owing to relative movement to the steel pipe 10, the fluctuation being large, so corrosion, crack, etc., are detected based on changes in the detection voltage.
