Title: Water purifying device
Inventor: SAWAGUCHI MAREYOSHI
IPC: C02F9/00
Filed: 1991-07-09
Abstract: PURPOSE:To remove sufficiently not only remaining chlorine but also org. halogen compd. such as agricultural chemicals, and trihalomethane and the odor of mildew by using at least a reducing substance and an activated carbon as filter mediums and cleaning water by passing the water at first through a reducing substance layer and then through an activated carbon layer. CONSTITUTION:In a water treatment device, at least a reducing substance and an activated carbon are used as filter mediums and water is passed at first through a reducing substance layer and then through an activated carbon layer. At first, remaining chlorine is chemically reacted thereby in the reducing substance layer to change it into a chlorine compd. being harmless and safe to the human body and to remove it. Then, org. halogen compd. such as agricultural chemicals and trihalomethane, and substances being the origin of the odor of mildew such as 2-methylisoborneol and diosmine are adsorbed in the activated carbon layer to remove them. As the reducing substances, calcium sulfite, L-ascorbic acid, salts of L-ascorbic acid, L-ascorbates etc., are pref. used and as the activated carbon, the shape may be particulate or fibrous.

Title: Automatic focusing camera and range finding method
Inventor: TAKU MASAKAZU
IPC: G03B13/36
Filed: 1986-11-05
Abstract: PURPOSE:To make a proper focus adjustment to an object which approaches or moves away by computing information on the distance to the object at the exposure point of time of a camera based on a range measurement result, and generating the focus adjustment signal of an objective from the arithmetic value. CONSTITUTION:A range measuring circuit 12 computes the distance A to the body based on the output of a photosensor 7 and stores it in a 1st storage circuit 13. Then a timer circuit 11 sends a trigger signal to a driver circuit 10 and the range measuring circuit 12 at a time t1 after a 1st light projection, and the range measuring circuit 12 calculates and stores the distance B to the body at the time T1 later in a 2nd storage circuit 14. A time t2 is only set by a 2nd timer circuit 17 and than a correcting circuit 18 calculates the movement distance by which the body moves from a 2nd range measuring circuit until a shutter is open as vX(t2-t1)=f2 based on the moving speed (v). Therefore, a subtracting circuit 19 subtracts a correcting quantity f2 from the former distance A to find the distance (c) to the body when exposure is actually performed.

Title: Refrigerator
Inventor: NONAKA HIKARI
IPC: F25D17/06
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To reduce cost of a vegetable container and to enhance space efficiency of a vegetable chamber. SOLUTION: A cold storage chamber 2 and a vegetable chamber 3 are provided in communication therebetween in the refrigerator 1. A cold storage cooler 26 is disposed on a back surface of the chamber 2, and a refrigerant is supplied selectively to a deep freezing cooler 51.

Title: Fuel spacer of nuclear fuel for boiling water reactor
Inventor: OKUBO KAZUTOSHI
IPC: G21C3/356
Filed: 1991-09-17
Abstract: PURPOSE:To prevent fretting and the damage of a spacer ring by resiliently bringing the spacer ring for resiliently supporting an angular large-diameter water rod into contact with only four corners of the water rod. CONSTITUTION:Many spacer cells 8a are constructed on an outer circumferential part with the use of a support lattice plate 5 and water rod cells 8b are made by the use of four support side parts 5a at a shaft center side. Inserted fuel rods 1 are resiliently supported by the use of the spacer cells 8a. Angular large- diameter water rods 2 are inserted into the water rod cells 8b and resiliently supported by the use of spacer rings 7b. The springs 7b are brought into contact with only the four corner parts of the rods 2. Because deformation like a projection and a recess is not received at the corner parts 2b even if the pressure difference between the inside and outside of the rods 2 produces, fretting may be generated by the fact that the springs 7b are pressed by the support side parts 5a to break and separate.

Title: Purification of crude cyanhydrin
Inventor: BUORUFUGANGU BUUDAA
IPC: C07C255/16
Filed: 1990-10-04
Abstract: PURPOSE: To effectively purify a crude cyanohydrin by distilling off the unreacted reactants in vacuum by leading the vapors into the driving jet of the liquid jet pump driven by the crude material containing basic catalyst to promote the synthesis of cyanohydrin.  
     CONSTITUTION: After separating the unreacted reactants by vacuum distillation 3 of 3-6C crude cyanohydrin(CH) 19 contaminated with HCN and the starting carbonyl compound from production process 13, CH is produced by purifying said crude CH 19. Vacuum is formed with liquid jet pump 11 which partially condenses, if necessary, and leads self-vapor 10, generated by distillation 3 and containing CH reactants, to the driving jet of pump 11. Pump 11 is driven by crude CH containing basic catalyst. Stoichiometric synthesis of CH is achieved by connecting pump 11 to a cooled reaction circuit in which the crude CH reactants absorbed from self-vapor 10 are converted into CH, and by smoothly separating the unreacted reactants from said crude material.

Filed: 1987-10-23
Abstract: PURPOSE:To remove the useless resending of a self-generating token frame by deciding the capability of normal token repeating in the case of receiving a token frame generated from a self equipment after the passage of a prescribed time. CONSTITUTION:When a data transmission request is not generated from a terminal equipment, each of data transmission control equipments 302-305 repeats a token frame on a loop transmission line 301 to a downstream-side transmission control equipment. After completing the sending operation of the token frame, each data transmission control equipment sets a deciding period >=(token frame word length-1) octets and decides whether the end flag of the token frame generated from the self-equipment is received within the period or not. When the end flag of the token frame is not received within the period, that the leading part of the token frame is not repeated to the downstream is decided and resending is executed.
