Title: Mold temperature controlling apparatus
Inventor: TOYOSHIMA AKIRA
IPC: B29C45/73
Filed: 1986-03-28
Abstract: PURPOSE:To allow the direct use of cooling water without running a refrigerator when refrigerant temperature is high by a constitution wherein refrigerant to cool a condenser belonging to the refrigerator is allowed to mix with the refrigerant heat- exchanged at a mold. CONSTITUTION:A refrigerator is normally run in the state that valves 18 and 19 are closed and valves 4 and 16 are opened and cooling water comes from an inlet pipe 15 through a valve 16 into a condenser and escapes from an outlet pipe 29. Next, when high refrigerant temperature is allowed and the cooling water is directly used as refrigerant, the valves 18 and 19 are opened and the valves 4 and 16 are closed and then the running of the refrigerator is stopped. Thus, the cooling water flows not to the condenser but to a tank 1 through a cooling water bypass pipe 17 and a bypass pipe 6 so as to be sent by means of a pump 2 through a discharge line 3 to a mold 11 in order to be back through a return line 22 to the tank 1 after cooling the mold. In addition, the cooling water flowing through a bypass pipe 20 branched off from the discharge line 3 passes through the valve 19 so as to be discharged through the outlet pipe 29. In case that high refrigerant temperature is allowed as described above, temperature control is enabled by mixing the cooling water of the condenser in the refrigerant course.

Title: Windshield wiper device for automobile
Inventor: AOKI AKIO
IPC: B60S1/26
Filed: 1984-04-06
Abstract: PURPOSE:To make an operating area of a wiper arm enlargeable so sharply a range, by making the arm so as to vary its length while operating the wiper arm for wiping clean. CONSTITUTION:When a wiper arm 1 rocks itself centering on a wiper pivot 6, a driven gear 14 of a gear mechanism 11 rolls on a tooth surface of a fixed gear 13. On the other hand, since an actuating rod 12 is connected to a position being offset out of a turning center of the driven gear 14, it performs rectilinear motion with rotation of the driven gear 14, causing a sub-arm 4 to operate its retractable motion. A retractable stroke L of the sub-arm 4 is secured as a turning path diameter l of a connecting point 18 with the driven gear 14 of the actuating rod 12. Thus, the wiper arm is able to sharply enlarge its opening area because of varying its length while doing its wiping operation.

IPC: H01M4/48
Filed: 1986-03-27
Abstract: PURPOSE:To increase discharge performance by using a positive electrode prepared by molding a positive mix containing molybdic acid and applying heat- dehydration treatment to the mix. CONSTITUTION:Molybdic acid powder having a mean particle size of 3mum, graphite powder, and PTFE powder are mixed in a ratio of 4:1:0.4. The mixture is filled with a mold in the bottom of a positive can 2 in which a positive current collector made of stainless steel net is spot-welded, and is pressed under a pressure of 1.5 ton/cm to form a disk. Thereby, the molded disk is pressed against the bottom of the positive can through the positive current collector. They are heated in a vacuum at 250 deg.C for 15 hours. By this heating, molybdic acid in the molding is decomposed into molybdenum trioxide and water, and the water generated is scattered from the molding for dehydration. After dehydration, the molding is used as a positive electrode.

Title: Lead-acid battery using high specific gravity electrolyte
Inventor: TAKAHASHI KATSUTO
IPC: H01M10/42
Filed: 1986-03-26
Abstract: PURPOSE:To increase capacity and life by installing a reservoir in which high specific gravity electrolyte staying in the lower portion by the stratification of electrolyte is stored below a plate group, and supplying the high specific gravity electrolyte stored in the reservoir to the plate group during discharge. CONSTITUTION:High specific gravity electrolyte is temporary stored in a reservoir 3 installed below a plate group 2 by utilizing stratification formed on the way of charge to keep the specific gravity of electrolyte in a palte group 2 low. During discharge, the high specific gravity electrolyte stored in the redervoir 3 is supplied to the plate group 2 with an electrolyte circulator 4 to prevent decrease in the specific gravity of electrolyte in the plate group 2. Since the high specific gravity electrolyte in the reservoir 3 is not stirred by oxygen or hydrogen evolved from plates during overcharging, the specific gravity of electrolyte in the plate group 2 is not increased even after charge. Thereby, use of high specific gravity electrolyte is made possible and a lead-acid battery having high capacity and long life can be obtained.

The reagent layer 12 is constituted of water permeability layer and contains low-molecule enzyme, which transforms the diffusive material that is diffused and moved from the substrate layer 14 into more lower molecular weight. The reagent layer 12 also contains the reagent composition for detecting the low- molecule product. The substrate layer 14 contains an enzyme inhibitor for specifically inhibits human amylase and a calcium compound together. When the object to be measured is the low-molecule antigen, liquid, wherein the specimen, a high-molecule antigen and an enzyme label antibody are mixed, is dropped on the substrate layer 14, and the analysis is performed.
