Abstract: PROBLEM TO BE SOLVED: To obtain a hook mechanism, which can be used on a wall and also on a desk by selecting the projecting and non-projecting states of a U-shaped hook member, via a simple operation by utilizing the elastic force of the hook member made of a plastic material. SOLUTION: A hook 1 projecting over a holding port of a telephone main body fixed on a wall surface is engaged with a recess part 31 of a handset 3. Thus, a wall-type telephone set is made available. The U-shaped plastic hook 1 has the elastic force of a fixed level, and a recess part 16 of the hook 1 is pressed by a hook fall-out preventing pawl 21 of the telephone set. Therefore, a single end 12 of the hook 1 is engaged with a projecting part 23 of the handset 3, and the projecting state of the part 23 does not change even when the hook 1 has been pressed by the gravity of the handset 3. When the hook 1 is used on a desk, an operating part 14 of the hook 1 is pressed to cancel the engagement between the end 12 and the part 23 and to cancel the movement regulation of the hook 1. Then the hook 1 is moved down as shown by an arrow.  A square through-hole 15 of the hook 1 is fit into the part 23 by the elastic force of the hook 1. Thus, the hook 1 is set in a stable non- projecting state that can be easily reset in a projecting state.

Title: Automatic answering telephone set
Inventor: NISHINO YUTAKA
IPC: H04M1/64
Filed: 1984-12-21
Abstract: PURPOSE:To start the business recording operation immediately after the end of transmission of a response message by discriminating the end of transmission of the response message when the address generated by an address generating means coincides with the address, which is preliminarily stored and corresponds to the end of the message, at the response message reproducing time. CONSTITUTION:An address pulse AP outputted from an address pulse generating circuit 18 is inputted to a control circuit 20 in the reproducing operation state, and the counted-up recording address is compared with the recording position address which is stored in an internal memory and indicates the terminal recording position of the response message itself. If the coincidence is discriminated as the result of this comparison, the control circuit 20 judges that the transmission of the response message is terminated, and the circuit 20 forwards this recording tape fast. That is, the fast-forwarding operation is started immediately without reproducing a no-sound recording part. Then, the business coming from an originating subscriber through a line 1 is recorded.

IPC: G11B5/85
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To manufacture a high recording density recording medium with a high efficiency by a method wherein ions are implanted into a magnetic layer made of CoCrTa based alloy through a protective layer to micronize and isolate magnetic grains. SOLUTION: A magnetic layer 1 made of CoCrTa based alloy, CoCrTaPt based alloy, Co metal, CoCrNiTa based alloy, CoCrNiPt based alloy, etc., is formed on a substratel. Then, after H, He, Li or Be ions are implanted into a medium by an ion implantation method, a protective layer made of a-C or H (diamond-like carbon, DLC) is formed. If ion beams 3 are implanted into the magnetic layer 1, crystal defects 4 are produced and magnetic grains are micronized and isolated. With this constitution, the measured value of noises when a signal is reproduced in the case with ion implantation is about 1/3-1/4.4 of the value in the case without ion implantation, so that a high recording density can be achieved.

Title: Optical semiconductor element
Inventor: KAMEDA TOSHIHIRO
IPC: H01S5/06
Filed: 1992-09-14
Abstract: PURPOSE:To improve the absolute amount of refractive index change of a waveguide of an optical semiconductor element, without increasing the spectrum line width of light propagating in the waveguide, by heating at least a part of the waveguide, and thermally isolating the element part which is not heated from the heated part of the waveguide. CONSTITUTION:A metal resistor as a heating element 70 is arranged on a phase control region 2 of a 3-electrode variable wavelength DBR laser and on the electrode of a DBR region 3. The temperature of the passive waveguide is changed by the heat generated by the metal resistor, and causes the change of refractive index, so that the oscillation wavelength changes. By arranging the metal resistor at a position sufficiently distant from an active region 1, the temperature rise of the active layer is restrained, and the reaction is prevented. By applying electric power to the metal resistor, the wavelength can be shifted 10nm or more to the longer wavelength side. When the horizontal distance between the metal resistor and the active layer 1 is about 50nm, the thermal flow into the active layer can be sufficieintly restrained, and oscillation characteristics are not damaged.

IPC: G01M11/00
Filed: 1989-10-18
Abstract: PURPOSE:To measure the eccentricity of an element lens surface without hardly replacing a lens by providing a positive interchangeable lens and a positive or negative projection lens which are arranged on the side of a light source in order and movable on the optical axis. CONSTITUTION:A collimator lens 23 collimates light from the spot light source O1 consisting of a laser light source 21 and a condenser lens 22 into parallel light. A movable lens 24 generates spot light O2 at a focus position with the parallel light. The lens 24 is moved along the optical axis to shift the light O2 in position within a specific range. Further, the light O2 forms an image at a spherical position of a surface 27 to be inspected through a projection lens 25 or 26. Namely, the light is reflected by the surface 27 to travel backward along the onward optical path and become the parallel light, which is reflected by a beam splitter 28 and passed through the positive lens 29 to form a spot image I on a position sensor 30. The position of the image I moves on the sensor 30 according to the eccentricity of the surface 27. Therefore, the sensor 30 detects the position of the image I and takes an analysis to measure the quantity of eccentricity of the surface 27. Thus, the eccentricity of the element lens surface is measured without hardly changing the lens.
