Patent JP-S54100688-A (JP)
Title: Crystal vibrator
Inventor: MOMOZAKI EIJI
IPC: H03H9/56
Filed: 1978-01-25
Abstract: PURPOSE:To improve frequency/temperature characteristics of on bending vibration by combining two bending vibrations whose displacement directions intersect mutually, in a crystal vibrator of a relatively-low resonance frequency making use of bending vibrations. CONSTITUTION:To obtain the crystal vibrator, plate Z is turned counterclockwise on axis X by (phi) and then turned counterclockwise to axis Z on axis Y' by angle theta before being cut from an original crystal. This vibrator 61 is provided with upper and lower electrodes 62 to 65 divided, and electric fields are applied into vibrator 61 in directions of arrows 66 to 69. Further, a bending vibration inside of surface X'Y' is excited by electric fields 66 and 67 in mutually-opposite directions, and a Y'Z' bending vibration is excited by electric fields 68 and 69. Combining two vibrations improves resonance-frequency/temperature characteristics of one bending vibration. Further, a crystal plate cut at angles of (phi) and (theta) is polished to a thickness of 500mu and less and then the photo lithography manufacturing method is employed, thereby making it possible to mass-produce this vibrator.

Title: Preparation of vinyl chloride copolymer solution
Inventor: MIYOSHI SHIGETOU
IPC: C08F8/00
Filed: 1978-01-25
Abstract: PURPOSE: To prepare efficiently the solution of a copolymer containing vinyl alcohol units, having excellent thermal stability and containing a reduced amount of the alcohol, by saponifying a vinyl chloride-vinyl ester copolymer in the presence of an alcohol under specific conditions.  
     CONSTITUTION: A vinyl chloride coplymer consisting of 50W90 wt.% of vinyl chloride and 10W50wt.% of a vinyl ester, and having an average polymerization degree of 100W800, is diluted with an organic solvent to attain a viscosity of 500W 1,000 cps at ≤60°C, and saponified in the presence of an alcohol. The pressure is reduced to 100W200 Torr at ≤60°C to distill off the alcohol and the organic solvent, and increased to the normal pressure after the alcohol content of the saponification solution reaches ≤0.5 wt.%. Difficulty of the discharge of the product from the alcohol-removing apparatus because of foaming of the organic solvent is eliminated.

Title: Method and apparatus for monitoring state of load
Inventor: MASUMITSU HIROSHI
IPC: H02P29/00
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To detect the state of a load simply when the load is started or interrupted and to monitor the state of the load with high accuracy by a method wherein the detection value of the load is compared with a predetermined power upper-limit value and a predetermined power lower-limit value so as to be converted into a state detection flag which expresses the electrification state of the load. SOLUTION: A judgment and processing part 2 performs a required judgment or a required processing operation regarding input data from an analog input part 1, and a constant-cycle transfer part 3 outputs the result of the judgment and processing part 2 at a constant cycle. A state display/warning output part 5 displays the state of a load or outputs a warning on the basis of the output of a load-state discrimination part 4 which discriminates the state of the load. A flag/timer-value setting part 6 sets a state detection flag which expresses the present electrification of the load on the basis of the result of the comparison of a detected power value with a predetermined power upper-limit value and a predetermined power lower-limit value. Thereby, a timer flag is set in such a way that it is operated for a definite time since an electrification state is changed.  The combination pattern of the state detection flag with the timer flag is made to correspond to the actual electrification state of the load.

Title: Inspecting method for enclosed lead storage battery
Inventor: KIKUCHI YOICHI
IPC: H01M2/02
Filed: 1986-01-17
Abstract: PURPOSE:To decrease the lead time until a product is completed and reduce the production cost, by testing and classifying disordered cells with a pinhole or a rent from the amount of variation of the internal resistance before and after changing the outer air pressure. CONSTITUTION:A cell to be inspected is left in a decompressed ambiance and the inner resistance of the cell is measured and recorded after the cell comes to be a constant normal condition. After that, the cell is laid in the ambiance converted to the atmospheric pressure or a compressed condition compared with the former decompressed ambiance, and then the internal resistance is measured and recorded again after the cell is at a constant and normal condition. In this condition, the internal resistance of the cell is increased. When the cell is further left in the decompressed condition, the gas in the cell is exhausted through a safety valve, and an equilibrium is produced by the pressure difference responding to the valve opening pressure of the safety valve. On the other hand, when a good quality cell is laid from the decompressed ambiance to the atmospheric pressure or the compressed condition compared with the decompressed condition, the inner pressure of the cell is relatively reduced compared to the outer pressure, the jar resin film is contracted, the electrode plate group is pressed strongly by the outer pressure, the internal resistance of the cell is reduced consequently, and the internal resistance is left as the reduced condition even though the cell is left for a long period of time. Therefore, a good cell and a disordered cell can be classified.
