Title: Welding method for precipitation hardening type copper base alloy
Inventor: WATANABE YOSHIFUMI
IPC: B23K9/23
Filed: 1988-05-23
Abstract: PURPOSE:To prevent a weld zone from being softened and to improve working efficiency by surrounding an objective part to be welded and fitting a water- cooling member such as moisture cloth or a conduit pipe thereto to perform welding. CONSTITUTION:The annular conduit pipe 2 is arranged to the surface of a casting mold 1 so as to surround the objective part such as a cracked part A. Flux 4 is then supplied to the weld zone and cooling water is circulated through the conduit pipe 2. Welding torches 3 are disposed to face oppositely above the weld zone and while a gaseous Ar, etc., are discharged from the torch tips, a built-up welding of the title precipitation hardening type copper base alloy is performed on the cracked part A. Since welding is performed while cooling the weld zone and its vicinity, a high-temperature rise of the temperature of the weld zone is prevented. By this method, flocculation and a softening phenomenon of deposited particles of the precipitation hardening type copper base alloy can be prevented. Accordingly, the weld zone is prevented from being softened and the working efficiency of welding is improved.

Title: Thermal transfer printer
Inventor: MONNAI ATSUSHI
IPC: B41J33/14
Filed: 1987-05-22
Abstract: PURPOSE:To prevent the smearing of a recording paper with an ink or folding of an ink ribbon from occurring, by releasing the pressing of a printing head against a platen in the condition where take-up of the ink ribbon is stopped, and again driving the ink ribbon after the head is separated from the recording paper. CONSTITUTION:When the final dot in a printing line is printed, take-up of an ink ribbon 10 is stopped in the condition where a carriage 1 is continuedly moved. The pressing of a printing head is released in this condition, so that a take-up tension is not exerted on the ink ribbon 10 at the moment the head 3 is separated from a recording paper 11. Therefore, no slip occurs between the paper 11 and the ribbon 10, and contamination of the paper 11 does not occur. With the head 3 separated from the paper 11, the ribbon 10 is again taken up for a predeterimed period of time, so that a slack in the ribbon 10 is straightened, and the ribbon 10 is prevented from being folded at the start of printing of the next line.

Title: Preparation of glyoxylic acid
Inventor: MITANI TADAYOSHI
IPC: C07C59/153
Filed: 1981-08-12
Abstract: PURPOSE:To obtain glyoxylic acid useful for a reaction with a phenol in high selectivity advantageously even in high conversion ratio of a raw material, by reacting an aqueous solution of glyoxal with chlorine as an oxidizing agent. CONSTITUTION:An aqueous solution of glyoxal is reacted with chlorine of a simple substance as an oxidizing agent, preferably under pressure and preferably in such a way that the concentration of hydrochloric acid prepared as a by- product in the aqueous solution is controlled at 1-15wt%, to give glyoxylic acid in high conversion ratio of >=90% and in high selectivity of >=80%. Since the reaction is controlled by regulating the feed speed of chlorine in this process, the reaction is controlled easily, and large-scale fixed devices are not required. This process can use raw materials with lower quality than nitric acid oxidation process, and the resultant reaction mixture can be used directly in a reaction with a phenol, etc.

Title: Timer apparatus
Inventor: YAMANISHI KAZUHIRO
IPC: G04G15/00
Filed: 1983-07-12
Abstract: PURPOSE:To enable the operation of a timer simply without remembering the way of operation by calculating the end time with an arithmetic section from numeral for start ing time and operating time intervals to allow the inputting in the order of words. CONSTITUTION:For example, when recording is to be done for 2hr from nine o'clock, keys should be pressed in the sequence of ''9'', ''o'clock'', ''from'', ''2'', ''hours'' and ''VTR''. Initially, ''9'' is inputted into an input buffer 3 by inputting the numeral key for the values and when ''o'clock'' is inputted, the value of ''09'' is inputted into an hour register 5. When ''2 hours'' is inputted, ''02'' is entered into the hour register 5. With the inputting of ''hours'', this value and the contents of a start time register 6 are computed with an arithmetic circuit 14 and the results are entered into an end time register 7. Hence, the contents of the end time register 7 give ''1100''. Thereafter, by inputting ''VTR'', setting is made so that a video tape recorder starts operation at the operation time with a timer. This enables the inputting in the order of words to allow the operation of the timer so simply as to eliminate the need for remembering the way of operation.

Title: Digital signal circuit and its operation confirmation system
Inventor: TERAO YASUHIKO
IPC: G06F11/00
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To confirm the operation of an input circuit inexpensively by judging the normality or abnormality of circuit operation by a signal outputted corresponding to the opening/closing of the contact of a switching part provided at an input switching circuit part, and to save a space for confirming the operation of the input circuit. SOLUTION: In a normal state where operation is not confirmed, the contact TC1 of an input exchanging circuit EX is closed and a contact TC is opened. In order to switch inputting from this state, TC 2 is closed. Since each input circuit 1 to 3 is equivalent to the simulation of a state where contacts C1 to C3 are normally closed at this time, an operation judging means J1 fetches the signals A1 to A3 of the circuits 1 to 3 to investigates whether or not all the photocouplers PCA1 to PCA3 are lighted and conducted. Namely, it is investigated whether or not all the digital input circuits recognize the contacts C1 to C3. When all the circuits 1 to 3 are lighted, circuit operation is judged to be normal but when even only one of them is not lighted, the circuit operation is judged to be abnormal. Thus, the characteristic variation of the input circuits can simply be detected.

Abstract: PURPOSE:To allow the equipment to disregard a malicious call when a received call is the malicious call by referencing a malicious call information storage memory at the arrival of the call and using a connection reject signal transmission section to send a connection reject signal to an exchange when the malicious call is stored. CONSTITUTION:When a connection request comes from a subscriber terminal equipment 1b and a call signal is sent via a subscriber trunk 5a from a call signal transmission trunk 6a, a subscriber terminal equipment la compares a caller subscriber number sent from an exchange 2a with a malicious call caller number stored in a malicious call information storage memory 12 by using a malicious call retrieval section 14. As a result, when they are coincident, no signal is sent to a call tone generating section 15 and a malicious call detection lamp 11 is lighted and a connection reject signal is sent to the subscriber trunk 5a from a connection reject signal transmission section 17. When a malicious call comes in this way, no call tone rings at the subscriber terminal equipment 1a and only the malicious call detection lamp 11 is lighted.
