IPC: G11B15/10
Filed: 1989-07-20
Abstract: PURPOSE:To switch a mode by means of one plunger by controlling the attracting timing of the plunger in a logic control type cassete tape recorder. CONSTITUTION:When a trigger lever releases the engagement from the engaging parts 25a and 25b of a cam gear 24 by the attracting action of the plunger 47, the rotation of the cam gear 24 is started.

Patent JP-H0237781-A (JP)
Title: Photoelectric semiconductor element
Inventor: YOKOYAMA HIROYUKI
IPC: H01L31/0248
Filed: 1988-07-27
Abstract: PURPOSE:To realize an ultrahigh-speed operation in a prescribed region by a method wherein a semiconductor layer displaying electrical conduction by irradiation with light is used as a quantum well layer sandwiched between two barrier layers and an effective life of a carrier in this quantum well layer is controlled by utilizing a resonance tunneling phenomenon via the barrier layers. CONSTITUTION:A quantum well layer 103 sandwiched between a first barrier layer 101 and a second barrier layer 102 is utilized as a photoconductor. When an impurity doping concentration is e.g., about 10<15>cm<-3> or lower, an electric conductivity of the quantum well layer 103 is very small; however, when a carrier of about 10<17>cm<-3> or higher is generated by irradiation with light, the electric conductivity becomes high. During this process, when a thickness of the second barrier layer 102 is extremely thin, an electron existing in a ground level 111 of the quantum well layer 103 flows out, as a tunnel electron 121, to an electron suction layer 104 whose minimum energy is low and where a nearly continuous energy level exists. Accordingly, an effective life of the carrier in the quantum well layer 103 becomes short down to the order of picoseconds. Thereby, an ultrahigh-speed operation in a picosecond region can be executed.

IPC: E04B1/86
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To absorb sound waves of two wavelength ranges by one sheet by forming one sheet and giving the sheet many pores and internal micropores. SOLUTION: This soundproof sheet is obtained by forming a porous metal body 3 which has many pores A into a sheet. The porous metal body 3 consists of a skeleton part 3a which covers the pares A and the skeleton part 3a is formed of a porous metal sintered compact having internal micropores (a) smaller in diameter than the pores A inside. Those pores A and internal micropores (a) have their internal diameters set to 0.1-5mm and 0-200μm respectively corresponding to the wavelengths of two kinds of wavelength range to be absorbed for sound characteristics that a speaker box needs to have. Therefore, the sheet can easily be stuck and laid and the pores which are large in diameter and the internal micropores which are small in diameter absorb sound waves of a long-wavelength range and a short-wavelength range among entering sound waves.
