Title: Inverse taper type two-shaft screw extruder
Inventor: NODA BUKO
IPC: B29C48/35
Filed: 1990-05-28
Abstract: PURPOSE:To suppress both rise of a temperature and back flowing amount of a material upon generation of heat and to improve an extruding efficiency by composing screws each having a small diameter of a root and a large diameter of an end in an inverse taper, and substantially horizontally disposing the shafts of screws. CONSTITUTION:When a sheet material 14 is produced, a material 10 is supplied from a kneader of an upstream side to the opening 5 of a casing 1 through a chute 4. The material 10 is forcibly extruded to the side of calender rolls 12, 12 by a pair of screws 6, 7 rotating reversely. This is formed to a sheet while rolling it by the pair of rolls 12, 13. In this case, since the screws 6, 7 have reverse tapers, a compression ratio of a metering zone of a discharge side to a feeding zone of a root side can be reduced to about 12. Accordingly, the rise of a temperature due to heat generated from the material 10 can be reduced that much, and the back flowing amount of the material 10 is reduced to improve an extruding efficiency.

Filed: 1978-11-11
Abstract: PURPOSE: To obtain a low-cost ladder-type D/A converter by dividing the resistance circuit network and also facilitating the control for security of the resistance accuracy of the resistance circuit network at the time of manufacture.  
     CONSTITUTION: The ladder-type D/A converter, which is hitherto constituted with the resistance circuit network of a set of circuit 20, is formed with the resistance circuit network of two sets of circuits 20 and 30 plus buffer 40 with gain control terminal 43. As a result, the number of the resistance circuit network can be decreased although the resistance accuracy of the network is equal to the conventional circuit 30 which takes charge of the higher-rank bits, and at the same time the resistance accuracy can be eased more than the conventional for the resistance circuit network of circuit 20 which takes charge of the lower-rank bits. Accordingly, the control can be facilitated for security of the resistance accuracy by selecting properly the allotment of the higher- and lower-rank bit number in consideration of the gain control of buffer circuit 40. As a result, the cost can also be reduced.

Title: Separate type heat exchanger
Inventor: OHAMA MASAHIRO
IPC: F28D1/04
Filed: 1988-06-06
Abstract: PURPOSE:To eliminate heat transfer from a high-temperature section to a low-temperature section through fins and reduce the operating pressure of a heat exchanger, by separating the group of fins on the high-temperature section of the heat exchanger, whose operating fluid is refrigerant, from the group of fins on the low-temperature section. CONSTITUTION:Refrigerant in the condition of saturated vapor enters into a first heat exchanger 1 through an entrance 8 and the condition thereof is changed into the condition of two phases of gas and liquid after dissipating heat in the group 3 of heat transfer tubes while the refrigerant enters into a second heat exchanger 4 through a connecting tube 7 and is brought into the condition of supercooled liquid after dissipating heat in the group 6 of the heat transfer tubes, then, is discharged out of the outlet port 9 of the heat transfer tube. The condition of the refrigerant is changed in such a manner and, therefore, the first group of fins 2 of the first heat exchanger 1 as well as the first group 3 of heat transfer tubes of the same heat exchanger 1 keep a high temperature but the second group 5 of fins and the second group 6 of heat transfer tubes of the second heat exchanger 4 become a low temperature. The first heat exchanger 1 of a high temperature is separated from the second heat exchanger 4 of a low temperature to eliminate the movement of heat from the high-temperature section to the low-temperature section while the low-temperature section is arranged at the upstream side of air to increase the degree of supercooling (dt) at the outlet port 9 of the heat transfer tube.

Title: Nonaquoeus electrolytic secondary battery and manufacture thereof
Inventor: KIDA YOSHINORI
IPC: H01M10/0568
Filed: 1994-06-21
Abstract: PURPOSE:To make voltage change in the final stage of discharge gently to easily detect the remaining capacity by using a mixture of graphite and a lithium-containing metal oxide in a negative electrode capable of absorbing/ desorbing lithium. CONSTITUTION:By adding a lithium-containing metal oxide to graphite, deintercalation (release) of lithium from the metal oxide is generated in the final stage of discharge and sharp rising in negative potential, or sharp drop in battery voltage is retarded. As a result, since battery voltage gently drops in the final stage of discharge while battery capacity and potential flatness are maintained, by detecting voltage in this part, the remaining capacity is easily detected. By controlling the mixing ratio of the lithium-containing metal oxide to 0.1-30wt.%, discharge capacity at 2.75-3.5V is increased, and the remaining capacity is easily detected. In addition, by limiting to 1-10wt.%, battery performance obtained by the complete discharge is enhanced.

Abstract: PROBLEM TO BE SOLVED: To provide an autofocusing device having complete accuracy in the vicinity of the focus of an objective lens and capable of performing excellent autofocusing operation. SOLUTION: While monitoring output from a 3rd subtraction circuit 13, a controller 500 decides the moving direction of a surface to be examined 8 from the sign of the output from the circuit 13 at the point of time when autofocusing operation is started, and continues to move the surface 8 in the moving direction. When the absolute value of the output from the circuit 13 is under a previously decided set value, monitoring the output from a photodetecting element 14 is started. The set value is within a range where the output from the element 14 is monotonously increased or decreased with respect to the moving amount of the surface 8 in a focus direction. Thereafter, the movement of the surface 8 is continued without changing the moving direction of the surface 8. When the output from the element 14 is zero, the movement of the surface 8 is stopped.
