Title: Optical information recorder
Inventor: NAKAO TAKESHI
IPC: G11B7/135
Filed: 1985-03-11
Abstract: PURPOSE:To reduce the variance of the optical power of a diffracted beam to record, reproduce, and erase information stably by modulating the frequency applied at the erasing time with a prescribed frequency and oscillation plural condensed spots in the track direction with a prescribed frequency. CONSTITUTION:An A/O driver 9 consists of an oscillating circuit 101 which has (n+1) oscillators having frequencies f0-fn, a mixer circuit 102 which controls signal intensities of these frequencies, an adding circuit 103 which adds these signal intensities, and an RF amplifier 104 which amplifies the synthesized signal. Frequencies are applied to a transducer 105 attached to an A/O element 3 to obtain (n+1) beams at the erasing time, and an artificial elliptic spot consisting of one circular spot for reproducing and n circular spots for erasing is formed. The frequency f0 for the recording/reproducing spot is fixed in the oscillating circuit 101, but frequencies f1-fn for erasing spots are modulated and this frequency modulation is controlled by the signal from an external controller 106.

IPC: H04W88/06
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent a portable telephone part from generating noise when a pager part is receiving signals so as to improve the receive sensitivity to a pager signal by preventing the portable telephone part from performing a receive operation when the pager part performs the receive operation. SOLUTION: A pager operation signal that shows on/off of a receive operation in a pager receiving part 2 is sent to a common controlling part 4. The on/off state corresponds to the on/off state of a switch 6 and a pager controlling part 3 sends the on/off state of the switch 6 as a pager operation signal to the part 4. The part 4 switches the on/off of a switch 5 based on it and controls a receiving operation of a portable telephone in a telephone part 1. That is, when the on/off of the switch 5 alternates in a fixed cycle, at an on-time, the pager operation signal from the part 3 is checked and the switch 5 is controlled not to be turned on when the part 2 is on.

Abstract: PURPOSE:To perform processing along the edge of a substrate accurately even if there is a deviation in the edge position of a substrate. CONSTITUTION:The processing along the edge of a square-shaped substrate is executed by shifting four pieces of substrate edge cleaning blocks 10a-10d, each of which has an upper solvent nozzle 52, a lower solvent nozzle 53, and a gas nozzle 54, severally along the four sides of the square-shaped substrate. The substrate edge cleaning blocks 10a-10d have two position sensors 55 and 56 each which detect the positions of the edges of the square-shaped board, and also, they can be shifted in the direction (X direction) where they come close to or separate from the edges of the square-shaped substrate. Based on the detection signals by the position sensors 55 and 56, the direction in X direction of the substrate edge cleaning blocks 10a-10d are controlled to always follow the edges of the square-shaped substrate. Hereby, the processing is performed while following the edges of the substrate, high accuracy is not required for the mount position of the substrate.

Title: Vessel for pretreating hot iron
Inventor: NAGAI HARUYA
IPC: C21C1/06
Filed: 1980-04-11
Abstract: PURPOSE:To prevent the damage of the lining of a vessel for pretreating hot iron due to melting in pretreatment by lining the vessel with a refractory layer and a refractory layer contg. graphite and silicon carbide and further forming a glassy treated coat. CONSTITUTION:Hot iron before refining to steel is poured into a vessel, and soda ash, lime, iron ore, etc. are added to preliminarily desiliconize, desulfurize and dephosphorize the iron with contained Na, Ca, Fe2O3, etc. At this time, basic slag contg. Na, Ca, etc. is produced and forms a low m.p. compound together with the lining of the vessel to damage the liming due to melting. In order to prevent the damage, refractory layer 2 is laid on the inside of iron shell 1, and refractory layer 3 contg. graphite and SiC on layer 2. When layers 2, 3 are precaecined and baked after pouring hot iron, molten slag in the iron reacts with SiO2 produced by the oxidation of SiC to form glassy CaO-SiO2-Fe2O3 coated layer 5. Layer 5 prevents the damage of the lining due to molten slag in the prerefining of hot iron.

Filed: 1989-02-28
Abstract: PURPOSE:To facilitate the control of film thickness by forming a saturation absorption layer capable of freely setting the film thickness in a specified range, as the surface layer for impurity introducing and regrowing. CONSTITUTION:After a lower side clad layer 2, a quantum well active layer 3, a first upper side clad layer 4, and an Si-doped MQW optical waveguide layer 5 are respectively grown on a GaAs substrate 1, a saturation absorption layer 11 of GaAs is grown. Next, a stripe-type region turning to the optical waveguide is irradiated with a convergent Be ion beam 10, thereby growing a second upper side clad layer 8 and a P-type GaAs contact layer 9 on the layer 5. After that, an amorphous region 7 and the MQW optical waveguide are formed by heat treatment. Since the layer 11 capable of freely setting the film thickness in the range of 50-200Angstrom  is formed as the surface layer for impurity introducing and regrowing, the film thickness can be easily controlled.

IPC: G11B15/08
Filed: 1980-04-10
Abstract: PURPOSE:To exercise effective control over the run of a tape, by performing the confirmation of a tape loading state and the detection of a tape mark through a one set of optical mechanisms. CONSTITUTION:At a recording and reproducing mechanism part facing to bottom plate 21 of a tape cassette, photodetector 20 is set in the direction of tape 11 and at the counter position, light source 19 is set. Bottom plate 21 is provided with opening 22 and when tape 11 is not loaded, direct light from light source 19 is photodetected by photodetector 20. As a reflection tape (tape mark) stuck to tape 11 reaches a light irradiation part, its reflected light is received by reflex mirror 23 under bottom plate 21 and then photodetected by photodetector 20. Therefore, the loading of tape 11 is detected by utilizing the occlusion of light to photodetector 20, and consequently the state enabling to start the drive of the tape is set. The tape mark of an endless tape is detected by using reflected light, so that the displacement of the head mechanism is controlled.

Filed: 1983-03-23
Abstract: PURPOSE:To effectively prevent the overcurrent due to the variation in a load or a shortcircuit by stopping supplying to the primary side of a high voltage transformer when a load current becomes excess. CONSTITUTION:In case that an excess current flows to a load 8 due to a shortcircuit of a load 8 or a defect of a controller 5 or a differential amplifier 6 when a high voltage output is presented at the secondary side of a high voltage transformer T1, a Zener diode ZD2 becomes ON, and a current flows through resistors R9, R10. Thus, a transistor Tr4 becomes ON, the drive of a transformer T2 is stopped, and high voltage output to the secondary side of the transformer T1 is stopped. An oscillation controller 5 is provided to control the output of the transformer T1 in response to the load current of a load 7. Even when the load current of the load 7 becomes excess, the transistor Tr4 becomes ON, and high voltage to the secondary side of the transformer T1 is stopped.
