Abstract: PURPOSE:To prevent a focus state from being generated by mistake by providing a detecting means that detects whether the total quantity of reflected light from a base face and a recording face is in a defocus area having a level less than specified quantity of reflected light characteristic. CONSTITUTION:A defocus area detecting means that receives total quantity of reflected light SSUM that indicates characteristic of changing of levels of returning light P1-P3 from the base face and recording layer face depending on the distance between a recording medium 3 in which a recording layer is provided on the base and the objective lens 12 side and judges whether the total quantity of light SSUM is in a specified defocus area ADF on the characteristic or not is provided, and a defocus adjusting means that sets the objective lens 12 to defocus state is formed by the detecting means. A defocus level that does not cause the destruction of recorded information below the level VO is obtained. Thus, existence at the defocus position can be detected exactly by monitoring total quantity of reflected light, and accordingly, becoming focus state by mistake can be prevented surely.

Title: Super high frequency transmiter
Inventor: TANAKA HIROKAZU
IPC: H01P3/127
Filed: 1978-04-05
Abstract: PURPOSE:To prevent the deterioration of oval polarization rate and the oxidation of the conductive material, by coating a conductive material on the inner surface of tubular member in a transmiter then further coating a protective film. CONSTITUTION:0.5-2 micron depth of conductive film 6 is formed on the inner surface of conical born 1 made of carbon fiber reinforced plastic (CFRP) through aluminium evaporation. SiO2 is further deposited over it as a protective film 7 for the aluminium film 6. The depth of said protective film 7 is preferable to be 0.05- 0.2 micron. Since the conductivity at the inner surface of said horn 1 is increased, the deterioration of oval polarization rate can be prevented while simultaneously the oxidation of the conductive material can be prevented.

Abstract: PURPOSE:To perform the timing measurement at the measuring place of a sample in a short time, by controlling the phase of an electron beam pulse so that the voltage of the sample at the measuring place agrees with a specified potential with a binary search means. CONSTITUTION:A binary search means 1 converges and processes an electron beam pulse so that the voltage of a sample at a measuring place agrees with a specified potential.

The convergence limit range for the specified potential in the convergence-limit judging means 2 is set as a voltage measuring value + or -voltage resolution under the condition wherein the voltage resolution in a voltage measuring system is set at 1/4 the amplitude of the measured waveform. An addition/averaging means 3 finishes the binary search and starts the addition and averaging when the parameter used in the binary search becomes the value within the preset convergence limit range, i.e., the range of the voltage measuring value + or - voltage resolution.

Title: Recorder
Inventor: NAKAJIMA YUJI
IPC: B41J9/38
Filed: 1986-02-27
Abstract: PURPOSE:To enable reduction of noise generated when a recording hammer has returned by providing a means to absorb an impact almost at right angles with the movement direction of a recording hammer and giving a braking force or a damping force to the latter. CONSTITUTION:When energization of a coil 7a, 7b is suspended and a coil 4a is energized, a recording hammer 4c abruptly advances, resisting a spring. Then the hammer strikes the back of a type 5a and performs recording operation through an ink ribbon 6a. Next, when a coil is demagnetized, a hammer 4c returns to an initial position with the help of a repulsive force of a return spring and that of a platen 1. However, when a douser 10 of the hammer interrupts the optical axis 8 of a photointerrupter 8, the coils 7a, 7b are energized, causing the protrusion 7c of a yoke 7 to attract the flange 4j of a part to be attracted by the hammer. Consequently, the hammer 4c is braked gradually coming to a stop. Thus noise of the while unit during recording can be effectively reduced.

Title: Electrophotographic sensitive body
Inventor: YOSHIZAWA HIDEJI
IPC: H01L31/08
Filed: 1986-02-26
Abstract: PURPOSE:To improve the electrostatic chargeability and the sensitivity in a wide wavelength region to the near infrared region by providing a laminate type structure obtd. by interposing a specified barrier layer between a specified photoconductive layer and an electrically conductive support and forming a specified charge retentive surface layer on the photoconductive layer. CONSTITUTION:The barrier layer 22 is made of microcrystalline silicon contg. at least one among carbon, nitrogen and oxygen, so it has high specific resis tance and superior charge retentivity. An element belonging to the group III or V of the periodic table may be incorporated into the barrier layer 22 so as to convert the layer 22 into a P- or N-type layer. The photoconductive layer 23 is made of amorphous silicon contg. hydrogen, so it has high sensitivity to light having long wavelength. The surface layer 24 is made of boron nitride contg. hydrogen, so moisture and nitride are hardly adsorbed on the layer 24 and an image is kept clear. Since boron nitride has a large optical band gap and hardly absorbs incident light, incident light reaches the photoconductive layer 23 at a high rate and is absorbed in the layer 23, resulting in high carrier generating efficiency.

Abstract: PURPOSE:To perform high-speed, high-operation of a load body by providing a large-amplitude vibrating section at time of the load body being coupled and a transferred quantity detecting element with vibration absorbers. CONSTITUTION:A motor rotor 5 is coupled with the input axis of a harmonic drive type speed reducer 14, and its axis 15 is coupled with a load body.

Usually the torsional rigidity of the speed reducer 14 is smaller than the rigidity of a load body, and vibration caused by the torsional rigidity of the speed reducer exerts a baneful influence upon the motor control system. Then a high-damping member 8 and a deadweight 9 are provided on the output axis 15 as a vibration absorber, and a high-damping member 6 and a deadweight 7 are provided in the periphery of a transferred quantity detector 4 as a vibration absorber to damp vibration effectively.

Abstract: PURPOSE:To reduce relative intensity noise(RIN) and to simplify the structure, by combining optically an intensity modulated laser diode(LD) and an optical fiber. CONSTITUTION:Light output from an LD 21 is conducted into an optical fiber 23 through an optical coupler 22. The input side of the optical fiber 23 is supported by a ferrule 24 while the output side is connected to an optical connector 25. Light is reflected on the surface of an optical part such as a focusing rod lens in the optical coupler 22. A reflection position 27 where light is reflected and the end of the LD 21 to output light are located so that they meet the conditions of the formula below. Supporting that the optical distance (the product of an actual distance and an average refractive index of a light path) between the end of the LD 21 to output light and the position where light is reflected is lR, the period of a modulated signal of the LD is T and the velocity of light (about 3.0X10<8>m/s) is (c), the reflection device should be located to meet the formula lR NXTXC/2 (N=1, 2, 3,...) for the reflected feedback light to enter the LD at the same time when the LD emits light.
