TM3, which is at or below the mold temp. TM1 at an initial injection time. At the time t3 when the cooling is finished, the surface layer temp. TS of a resin is cooled down at or below the heat distortion temp. T1 but the resin temp. of the central part TC is a little higher than the heat distortion temp. T1. A heater 11 is charged again and the heating medium is flown into the medium path 13 to heat the inserted top 1 of the fixed mold and the inserted top 5 of the movable mold and to return the mold temp. to the mold temp. TM1 at the initial injection time. During this mold temp. returning and compression process, the resin surface layer is heated, while cooling of the central part of the resin is continued. At the time t4 when returning the mold temp. is completed, both the surface layer temp. TS and the central part temp. TC of the resin are approximate to the mold temp. TM1 at injection.

Title: Frequency converting circuit
Inventor: NAKASHIMA SHIGERU
IPC: H03D7/14
Filed: 1980-01-17
Abstract: PURPOSE:To obtain a wide gain adjustment width, by making the characteristic of output current to the input signal into an operation characteristic nearly similar to DC to adjust the gain of the balanced mixer circuit by the receiving signal strength. CONSTITUTION:Transistors TRs Q6-Q11 constitute balanced mixer circuits respectively, and TRQ12 constitutes the constant-current source for these circuits. The constant-current value is determined by the base potential and resistance R2 and determines the gain of these circuits together with load impedance ZL consisting of capacitor C2 and coil L2. When the receiving signal is small, the automatic gain control signal applied to the base of TRQ4 is small, and these circuits have the gain determined by the constant-current value and impedance ZL. The receiving signal is applied to these circuits as it is. When the receiving signal becomes large and the automatic gain control signal becomes large, the gain of these circuits are lowered, and the input signal amplitude to circuits becomes narrow. When the input signal is larger furthermore, the input signal to these circuits becomes small.

Abstract: PURPOSE:To improve aberrations in spite of region expansion and to provide the compact zoom lens by providing an auxiliary lens which makes variable power further to a long focus side from a telephoto end by moving at least one of the lens groups constituting the main lens system further from the position at the telephoto end when the auxiliary lens system is inserted. CONSTITUTION:All of the 1st lens group I, 2nd lens group II and 3rd lens group III of the main lens system LT respectively move to an object side and the air spacing moves further from the telephoto end at the time of inserting the auxiliary lens system at the telephoto end of the main lens system LT. The restrictions on the lens constitution for the purpose of well correcting the various aberrations decreases as compared to the lens constitution with which the main lens system does not move if the main lens system LT is moved on the optical axis at the time of insertion of the auxiliary lens in such a manner; therefore, the adequate selection of a point where there is an allowance in the air spacing of the main lens system LT as the insertion position of the auxiliary lens is possible. The variable power region on the long focus side is expanded in this way and the good aberrations are obtd. in spite of the region expansion. The compact zoom lens is thus obtd.

Title: Hollow rotary body
Inventor: OKUYA TSUGUYUKI
IPC: F16J15/06
Filed: 1985-01-16
Abstract: PURPOSE:To improve the sealing performance by radially expanding an annular sealing member by the centrifugal force when a rotor runs at a high speed so as to enhance its close contact to the sealing part. CONSTITUTION:When a rotary body 1 runs at a high speed, an annular sealing member 9 is expanded externally by the centrifugal force so that said member 9 makes close contact with end plates 5 and 6, a cylindrical body 4 and a fixed ring 8. The grade of contact obtained at this time will get higher when the rotary body 1 revolves at higher speed. Even if a gap is produced between the cylindrical body 4 and the end plates 5 and 6 when flowing substance is carried inside the rotary body 1, the sealing performance may be improved because the annular sealing member 9 keeps close contact with both the body 4 and the plates 5 and 6.
