Title: Manufacture of reinforced pipe
Inventor: WATANABE KIMIO
IPC: B32B1/08
Filed: 1991-01-11
Abstract: PURPOSE:To prevent the deterioration in strength due to mutual peeling by making the linear expansion coefficients of a metal pipe and a reinforcing material almost equal when the reinforcing material impregnated with thermosetting binder is wound on the metal pipe and the same is thermoset in a heating oven to manufacture a reinforced pipe. CONSTITUTION:An embossing process on a recessed section having the depth of less than the wall thickness of pipe on the outer or inner peripheral face of a metal pipe in the peripheral direction is added preliminary to the manufacturing process of a reinforced pipe consisting of a process of winding a reinforcing material impregnated with a thermosetting binder on the outer peripheral face of the pipe and a process of heating the outer peripheral face of the metal pipe and thermosetting the reinforcing material. Mechanical potential stress to shrink all the time in the axial direction is applied to the formed recessed section, and the reinforcing material is not peeled off, as the shrinkage in the axial direction is not generated on the metal pipe itself when the reinforcing material is thermoset by inner-oven heating, and then released and cooled naturally.

Title: Manufacture of thin-film magnetic head
Inventor: TODA JIYUNZOU
IPC: G11B5/31
Filed: 1981-02-02
Abstract: PURPOSE:To improve characteristics and to reduce the cost for manufacturing by flattening the entire surface of a magnetic layer by mechanical polishing after forming the magnetic layer thicker than the depth of the recessed part in a prescribed pattern, and removing a magnetic layer part, influenced by work strain, by etching. CONSTITUTION:A recessed part in a prescribed pattern is formed on a substrate 1 and a magnetic layer 2 thicker than the depth of the recessed part is formed. The magnetic layer is polished slantingly to form a surface 9, which is smoothed by ion milling or etching treatment to prescribed size, e.g. about 1mum depth to remove work strain, thus forming an ion-milled surface 10. Then, lower magnetic layers 2 and 3 are formed as a lower magnetic layer 4. On it, a coil 5 is provided and after an insulating packing material 6 is packed, an upper magnetic layer 7 is formed and then covered with a surface insulating layer 8. Consequently, products having superior characteristics are manufactured by eliminating work strain.

Abstract: PURPOSE:To prevent a latch-up phenomenon in an A-D converting circuit by a converter wherein rising time of a DC power supply for a load cell and its amplification circuit is selected to be delayed comparing with a power supply for the A-D converting circuit. CONSTITUTION:A power supply sequence circuit is added to a power supply unit so that rising time of a DC power supply circuit for driving a load cell adapted to generate a signal proportional to the weight of a material to be weighed and an amplification circuit adapted to amplify the signal and then output it therefrom will be delayed comparing with a power supply for an A-D converting circuit adapted to digitalize output from the above circuit. For example, outputs generated in secondary windings 1a, 1b of an input transformer 1 are processed via rectifiers 2a, 2b, capacitors 3a, 3b and constant voltage circuits 4a, 4b to generate DC voltages across A B terminal and B C terminals for a load cell and its amplifier and to generate voltagfe across D E for an A-D converting circuit. On this occassion, a power supply sequence circuit 11 comprising transistors, resistors and a capacitor is added thereby to delay rising time of either one voltage as mentioned above.

At this time, with the printing plate 1 whose central part 2B is extending thinner than the both edge parts 2A, the fusion bonding defect of the central part occurs in some cases. Methods such as blowing of cold wind to the end parts 2A on the back side 3 of the photosensitive plate 1 or making the end parts 2A lower than the central part with a preheating roller 7 are employed for the prevention of this so that the both end parts 2A become lower by 0-20 deg.C than the central part. In this way, the uneven fusion bonding of the fine powder is prevented.

Title: Metal die for ic lead molding
Inventor: TAJIMA KIMINARI
IPC: H01L23/50
Filed: 1991-02-06
Abstract: PURPOSE:To prevent any danage to leads by providing a profiling plate attached to a die to the machanism for restricting movement of a punch. CONSTITUTION:An IC 9 is put on a die 2, a shedder 3 is moved downward and the IC 9 is held reliably. A punch holder moves downward and a roller 4 of the punch 1 comes to contact the inclines surface of a profile plate 8a. When the punch 1 moves further downward, the roller 4 is puched by the inclinded surface and the punch 1 rotates around the pin 5 in the arrow direction. Thereby, the end point of punch 1 preses the lead of IC 9 to the protruded portion 2b to form a lead. A mechanism for regulating movement of the punch 1 is isolated from the shedder 3 and the profile plate 8 is provided in the side of die 2. Thereby, the shedder 3 stably holds the IC 9 without giving any unexpected force to the shedder 3. Thereby, the lead can be protected from damage.

Title: Dial system
Inventor: TSUZUKI TAKUO
IPC: H04Q3/42
Filed: 1984-02-01
Abstract: PURPOSE:To continue the dial operation while using a correct dial number as it is before mis-dialing by allowing dial information of a special code and a revised digit number to correct a dial number storage memory. CONSTITUTION:After a caller 5 dials a mis-dial number 3, the caller dials a special code to change the mis-dialed number. Since the number storage program is brought into the correction processing preparation state of the mis-dialing number in this way, the caller dials a dial number representing a changed designation digit value, e.g., ''1'' succeedingly. The numeral storage program sets ''1'' to the changed digit number in an area 3, and corrects the numeral ''3'' of a dial number storage area 4 to ''2'' by using a corrected dial number ''2'' dialed succeedingly.

IPC: F01P3/02
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To supply high-temperature cooling water to a car heater by shutting- off the communication of a cooling water jacket with a cooling water outlet by a first valve body of a thermostat and the communication of the cooling water outlet with a cooling water exist pipe route by a second valve body during warming up where a cooling water temperature is low. SOLUTION: A thermostat valve 18 provided in an cooling water outlet 10 is composed of valve bodies 18a and 18b and a temperature sensing part 18c. When a cooling water temperature is low, the communication of a cooling water jacket 8 with the cooling water outlet 10 is shut off by the valve body 18a and, simultaneously, the communication of the cooling water outlet 10 with a cooling water exist pipe route 13 is shut off by the valve body 18b. Thus, during warming up where a cooling water temperature is low, all cooling water flowing into the cooling water jacket 8 is caused to flow in the direction of the other end part 8b in the cooling water jacket 8, then it is passed through a cooling water passage 17 to the cooling water outlet 10, it is then supplied from this place through a bypass pipe route 15 to a car heater 1 and thereby early warming is performed.

Abstract: PURPOSE:To simulate the depression effect of a side lobe by synthesizing the output of an antenna lobe pattern function generator and the output of a side lobe pattern function generator together. CONSTITUTION:When an operator does not select the operation of a side lobe canceler on a display 9, the coefficient alpha of gain coefficient multipliers 73a and 73b is equal to 0. When the operation of the side lobe canceler is selected, the coefficient alpha of the multipliers 73a and 73b is equal to 1, the output of antenna pattern function generators 71a and 71b and the output of side lobe pattern function generators 72a and 72b are combined together is subtracters 74a and 74b, respectively, and only a main lobe pattern is outputted. Therefore, only main lobe patterns in the output video signals of wave propagation modulators 6a and 6b are modulated by antenna lobe modulators 7a and 7b, respectively. Thus, an incoming wave from a side lobe direction, if any, does not constitute a simulated video signal and the operation of the side lobe canceler is simulated.
