Title: Manufacture of austenitic stainless steel stock excellent in nitric acid corrosion resistance
Inventor: INAZUMI TORU
IPC: C21D6/00
Filed: 1987-08-26
Abstract: PURPOSE:To manufacture an austenitic stainless steel stock excellent in nitric acid corrosion resistance at a low cost by subjecting a low-carbon austenitic stainless steel stock to heat treatment at a specific temp. and then rapidly or slowly cooling the above by specified method to ordinary temp. CONSTITUTION:After subjected, if necessary, to solution heat treatment at >=1030 deg.C, an austenitic stainless steel stock of <=0.02wt.% carbon content and, preferably, of <=0.02wt.% phosphorus content is subjected to heat treatment in which heating is applied up to 650-950 deg.C for >=1min. Subsequently, the heat-treated steel stock is cooled down to ordinary temp. by means of rapid cooling or allowing to stand to be cooled when heat-treating temp. is 650-850 deg.C or by means of rapid cooling when 850-950 deg.C. At this time, it is desirable to carry out the above rapid cooling at a cooling velocity where the stock does not pass through a temp. region of 350-625 deg.C over a period of >=30min. By this method, the austenitic stainless steel stock having high corrosion resistance to high-temp. nitric acid containing oxidizing metallic ions can be obtained easily and economically.

Title: Positive temperature coefficient thermistor device
Inventor: NITORI EIJI
IPC: H01C7/02
Filed: 1988-08-24
Abstract: PURPOSE:To maintain stable heat generation by means of the self-temperature control function of a positive coefficient thermistor 1 and to hold a predetermined temperature by incorporating a positive temperature coefficient thermistor in an insulation case having a one side opening, a terminal leading hole and a clamping hole. CONSTITUTION:A pair of terminals 2 are extended from opposed electrodes provided on one side of a positive temperature coefficient thermistor 1, and the thermistor 1 including part of the terminals 2 is coated with insulator in a predetermined thickness to form an insulation coating 3. The terminals 2 are inserted from an opening 4a into a pair of terminal leading holes 5, and the thermistor 1 is contained in the one side opening 4a of an insulation case 4 having the opening 4a, the holes 5 and a clamping hole 6. When a voltage is applied to the terminals 2, the thermistor 1 self- generates heat by means of Joule heat, and transfers it to an element to be heated through the coating 3. As time is elapsed, the quantity of generated heat of the thermistor 1 is balanced with the quantity of heat dissipation to the element to be heated to be stabilized at a suitable temperature. Thus, the thermistor can be press-fitted fixedly directly to the element to be heated through the coating with the elasticity of the case as a pressing spring to reduce its heat transfer loss thereby to improve thermal response and to reduce it in size and weight.

Title: Printing method in dot printer
Inventor: KAWASAKI NOBUTAKA
IPC: B41J2/255
Filed: 1986-09-08
Abstract: PURPOSE:To perform high quality printing of half dot constitution at a high printing speed, by setting the interval of dots in a lateral direction to a 1/2 dot pitch, and alternately repeating the driving of a left printing row and that of a right printing row at every two steps of a carriage. CONSTITUTION:Left and right printing rows L, R are driven in a step 1 and the dots of a b-row constituting a character are printed by the right printing row R. Next, only the right printing row R is driven in a step 2 to print the dots of a c-row. By this method, the left and right printing rows L, R are operated so that the alternate repetition of driving and non-driving is performed at every two steps of a carriage, and the row of the 1/2 dot pitch constituting a character is printed by two rows alternately by the left and right printing rows L, R. The min. interval wherein the same printing element of the same printing row is driven is the three-step of the carriage, that is, a 3/2 dot pitch interval. By this method, the response frequency of a printing head can be delayed by 2/3 with respect to the running of the one-dot pitch of the carriage and, when the response frequency is supposed to be the same, the running of the carriage can be set to 3/2 times.
