Title: Multistory parking device
Inventor: KONO MASAHIRO
IPC: E04H6/06
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To prevent an obstacle from protruding on the ground when an automobile which is parked on a lower side is stored in a pit. SOLUTION: In a multistory parking device, load of a rear half of pallets 11, 12 which are joined by front support columns 13a, 13b and rear support columns 14a, 14b and an automobile which is loaded is received by two hydraulic cylinders 15, 16. On the other hand, load of a front half thereof is received by two chains 26, 27 which are stretched between fixing parts A, B and fixing parts C, D. Since load is received by the hydraulic cylinders 15, 16 and the chains 26, 27 by sharing it in front and rear parts in this way, a portal support column for receiving imbalanced load in the front and rear directions is not required. Consequently, when the automobile loaded on the lower step pallet 12 is stored in a pit, no obstacle exists on the ground.

Title: High speed agc circuit
Inventor: IGA HISATAKA
IPC: H03G3/20
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To reduce pull-in time and to execute a stable AGC operation by maintaining the operation point of gain control voltage through the use of the output of a variable width pulse generator at the time of input switching or power supplying. SOLUTION: At the time of input switching and current supplying, the gain control of an amplifier 1 is switched to the pulse output of arbitrary pulse width in a pulse width variable pulse generator 6. Thus, the operation point of an AGC circuit is maintained. When the input signal of an input signal selector 8 is switched by a control circuit 7, for example, a detector 4 detects that the input signal is eliminated and a switching circuit 5 is operated. The input signal of a front stage, which is accumulated in the control circuit 7, is switched to the output of the pulse width variable pulse generator 6 controlled by the output of the detector 2 in a prescribed state and the gain control voltage of the amplifier 1 is fixed to a point near the operation point.  When the switched input signal arrives, the detector 4 detects it and the switching circuit 5 is switched to the output of the detector 2.

Title: Heterojunction type bipolar transistor
Inventor: KASAHARA TAKEMOTO
IPC: H01L21/331
Filed: 1988-09-20
Abstract: PURPOSE:To reduce base transit time as well as surface recombination by using a distorted semiconductor layer with a different grid structure as compared with a compound semiconductor forming an emitter region and a collection region for the compound semiconductor forming a base region. CONSTITUTION:A compound semiconductor with a larger lattice constant than that of a collector 2 and an emitter 4 is used for a base layer 3 of a heterojunction type bipolar transistor formed on a substrate 1 of face (111) B. Since carriers of the bipolar transistor thus obtained run on the base region 3 being accelerated by electric field, base transit can be reduced. Also, since electrons pass the base region 3 being accelerated, surface recombination can be reduced, thus increasing gain.

Title: Magnetic recording medium
Inventor: SASAMOTO SAYAKA
IPC: C10M105/54
Filed: 1991-08-24
Abstract: PURPOSE:To improve durability and traveling property by making combination use of specific unsatd. aliphat. fluoro group-contg. alkyl ester carboxylate and an antioxidant. CONSTITUTION:The unsatd. aliphat. fluoro group-contg. alkyl ester carboxylate expressed by formula I and the antioxidant are held in the magnetic layer on a nonmagnetic base. In the formula, R denotes an unsatd. aliphat. hydrocarbon group; (m) denotes integer >=4; (n) denotes integer >=1 and <=2m+1. While the unsatd. fluoroester carboxylate has an excellent lubricating effect, this fluoroester alone generates deterioration by oxidation with lapse of time and gradually decreases the lubricating effect. The deterioration of the ester by the oxidation is, however, prevented if the unsatd. fluoroester carboxylate and the antioxidant are used in combination and, therefore, the excellent lubricating effect is exhibited continuously over a long period of time.
