Title: Isothermal treatment of cast iron
Inventor: SATO KAZUO
IPC: C21D5/00
Filed: 1984-10-03
Abstract: PURPOSE:To prevent corrosion of electric furnace for next isothermal treatment by salt, by austenitizing cast iron under a specified treatment, cooling rapidly it by salt bath furnace, then removing salt adhered thereto under a specified condition. CONSTITUTION:Cast iron is heated to 830-1,000 deg.C and held for 0.1-5hr to austenitize the matrix structure by electric furnace, etc. of nonoxidizing atmosphere. The cast iron is cooled rapidly until the center temp. becomes the isothermal treatment temp. by salt bath furnace held to 220-420 deg.C said temp. In washing with water after said rapid cooling, water temp. and washing time are set so that surface temp. of cast iron returns to Ms point or above immediately after finish of washing process. Salt adhered to cast iron surface is solidified and washed out by the washing. Next, cast iron is thrown in electric furnace held to isothermal treating temp. of 220-420 deg.C to heat and hold it for >=5min, then cooled by air or water. By this way, corrosion of electric furnace by salt is prevented, and quality of product can be ensured.

Title: Production of tio2-cao-based sliding material
Inventor: WATABE KAZUYUKI
IPC: C04B35/46
Filed: 1989-08-09
Abstract: PURPOSE:To obtain the title sliding material which has a small bore and is excellent in sliding performance and also compatibility of thermal expansion coefficient with magnetic material by incorporating both TiO2 and CaO component derived from a specified supplying source at a prescribed molar ratio. CONSTITUTION:One or more kinds of supplying sources of CaO component are prepared which are selected from calcium oxalate, calcium acetate, calcium tartrate and calcium chloride. The supplying sources and TiO2 powder are mixed and this mixture is calcined and molded. The molded form is calcined in the atmosphere and thereby TiO2-CaO-based sliding material is obtained which incorporates 45-65mol% TiO2 and 55-35mol% CaO. Thereby generation of a big bore can be prevented which is caused on thermal decomposition in the calcining stage of the CaO sources because the supplying sources of the CaO component are specifically regulated. The obtained sliding material is preferably utilized as a slider for the magnetic head of a floppy disk device.

Title: Air conditioner for vehicle
Inventor: SAKOTA NORITSUGU
IPC: B60H1/32
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To improve vehicle mounting performance while reducing manufacturing cost of an air conditioner for a vehicle. SOLUTION: In an air conditioning casing 2, a pipe 7 is disposed such that it passes from an expansion valve 6 through a lower portion of the air conditioning casing 2, then extends from an evaporator to outside the casing 2. With this configuration, a separate space is not required for routing the pipe outside the air conditioning casing 2 and also a pipe connecting point is eliminated before a joint block 8. Therefore, a process for connecting the pipe 7 can be omitted and thus the manufacturing cost of a vehicle air conditioner can be reduced and also vehicle mounting performance can be improved.
