Title: Production of cyclic lactone
Inventor: YOKOTA TADASHI
IPC: C07D313/00
Filed: 1990-06-12
Abstract: PURPOSE:To increase the yield in production of the subject cyclic lactone from a, omega-hydroxyaliphatic acid containing an alpha,omega-dibasic acid as the starting raw material using the polymerization and depolymerization method by adding an alpha,omega-glycol in an amount of >=equimolar to the amount of the alpha,omega-dibasic acid in the raw material. CONSTITUTION:In production of a cyclic lactone by the polymerization and depolymerization method using, as the raw material, a omega-hydroxyaliphatic acid (B) containing an alpha,omega-dibasic acid (A) as an impurity, e.g. the compound (B) produced by using the compound (A) as the starting raw material, the reaction is carried out after adding an alpha,omega-glycol in an amount of >=equimolar to the amount of the compound (A) in the raw material to increase the yield of the objective compound. As the alpha,omega-glycol, one capable of ready separation from the product is preferable. In case of using the compound (B) produced from the compound (A), an alpha,omega-glycol obtained as a by-product in this reaction is preferably used because of its low cost and its easiness to obtain. The cyclic lactone is useful as an active substance, a perfume, an intermediate thereof, etc.

Title: Zoom lens barrel
Inventor: KAMIYAMA MASAYUKI
IPC: G02B7/10
Filed: 1983-08-19
Abstract: PURPOSE:To improve the precision of constitution wherein a part of lens group which moves in zooming moves even in focus adjustment by fitting a cam ring which has a degree of freedom in two directions, i.e. rotating direction and optical-axis direction around a fixed lens barrel, and transmitting the operation of a zooming ring and a focusing ring to the cam ring without mutual disturbance. CONSTITUTION:When the zooming ring 4 is rotated in zooming, the zooming ring 4 rotates without moving in the optical-axis direction and this rotation rotates the 1st moving frame 9 and a pin 15, so that the 1st moving frame 9 is extended forward while rotating. The cam ring 2, on the other hand, also rotates according to the rotation of the pin 15, and consequently cam grooves 1b and 2b of the fixed lens barrel 1 move relatively to move the 2nd moving frame 10. Further, the rotation of the cam ring 2 moves the cam grooves 2c and 2d, and the groove 1c of the fixed lens barrel 1 relatively to move the 3rd - the 5th moving frames 11-13. Thus, the zooming is attained and focusing rings 6 and 8 are still, in this case, together with the fixed lens barrel 1.

Title: Apparatus for testing electric circuit
Inventor: TANAKA KOICHI
IPC: G01R31/28
Filed: 1989-06-14
Abstract: PURPOSE:To increase the number of input and output terminals for the original operation by dispensing with the exclusive terminal for a test mode by continuing the generation of a signal until a power supply is cut off after a test mode order signal is once generated. CONSTITUTION:When predetermined voltage is applied to an input terminal 5 for a definite time from a signal source 15 in order to perform the test mode operation of an integrated circuit 1, a transistor Tr1 becomes a continuity state in a test mode order signal generating circuit 11 and, further, a Tr2 also becomes a continuity state. When the Tr1 and Tr2 once become a continuity state, both of them are in the continuity state until the power from a power supply 4 is cut off and a junction point 12 continues to hold a low level. The test mode order signal of this low level is applied to a test mode operation circuit 14 and the output of the circuit 14 is led out to an inspection circuit 16 from an output circuit 9 through an output terminal 10 to perform predetermined test mode operation. As a result, the arrangement of a test mode exclusive terminal can be made unnecessary.

Abstract: PURPOSE: To reduce the time to reach the information signal part after the regenerator element is lowered by installing the recorded area so that the reference signals featuring the equal frequency or the phase may exist at the both sides of the information track.  
     CONSTITUTION: In case the tracing is given to the general information signal track, tracking reference signals fp 1  and fp 2  are fetched through filters 12 and 13 from signals regenerated through pickup 10 and then supplied to differential amplifier 20 via switch circuit 17 plus detection circuit 18 and 19. While switch signal 4 is fetched through filter 14 to give trigger to FF16. The armature of switch circuit 17 is switched by the signal of FF16 and every turn. At the same time, pickup 10 is displaced toward the inner circumference when input signal 21 of the amplifier is larger than input signal 22. when the regenerator element is lowered into the outer edge circumference part, input signal 21 is supplied to amplifier 20 since signals fp 1  exist at the right and left of the track. As a result, pickup 10 is displaced forcedly toward the inner circumference.

Abstract: PURPOSE:To prevent incomplete combustion caused by injected fuel flowing onto a piston head by arranging the bore diameter of the bottom peripheral part of a combustion chamber and the height of a conical protuberant part at a central part inside said peripheral part to their specified values respectively. CONSTITUTION:A combustion chamber 2 is formed by indenting the surface of a piston head 1, and the peripheral part 3a of its bottom surface 3 is flatly shaped, and moreover a central part 3b inside it is conically protruded. In this case, the bore diameter dimension d of the peripheral part 3a is formed to about the half, namely 45+ or -5% of its outside diameter dimension D. In addition to that, the conically protruding height h of the central part 3b is formed to about the one third, namely 35+ or -5% of the depth H of the peripheral part 3a. Since a secondary swirl B is thereby controlled in its strength before and after passing through the peripheral part 3a, fuel injected through a nozzle 4 can exactly hit a target point P on the inner peripheral surface 2a of the combustion chamber 2.
