Title: Optical disk device
Inventor: MAEDA MIYOZO
IPC: G11B7/13
Filed: 1992-02-27
Abstract: PURPOSE:To suppress the fluctuation in the level of a reproduced signal in the optical disk device which executes reproduction by irradiating the optical disk with light from the protective film side of the disk. CONSTITUTION:This optical disk device is constituted by disposing a detector 10 for the reproduced signal which receives the light reflected by the protective film surface 6 of the optical disk in the position where the distance along the optical path 41 of the light reflected from an objective lens 22 is >=1.0 times the distance of A-times the focal length F of the objective lens (where A is the focal length of the objective lens/the thickness of the protective film). As a result, the laser beam reflected by a recording film 5 and the laser beam reflected by the front surface of the protective film 6 hardly interfere with each other on the surface of the detector 10 and the fluctuation in the output level is suppressed.

Title: Control device of air conditioner
Inventor: ARAI HIROAKI
IPC: F24F11/02
Filed: 1984-03-05
Abstract: PURPOSE:To suppress the power consumption by a method wherein the unnecessary power supply to the respective temperature detection circuits and the like is stopped when the operation of an air conditioner is stopped and, in addition, the power supply is performed intermittently only when necessary to the respective temperature detection circuits even when the air conditioner is in operation. CONSTITUTION:Because it is so programmed that the output Po goes to ''LOW'' when an air conditioner stands still, the transistor 18 in a power circuit is put out of actuation, resulting in supplying no power to temperature detection circuits 9 and 11. On the contrary, when the air conditioner is in operation, the temperature information such as room temperature, indoor pipe temperature and the like is necessary to be taken in, resulting in necessitating to put the temperature detection circuits 9 and 11 into operation. When the detection of temperature is intended, firstly the output Po is made to ''Hi'' and, after the elapse of a certain fixed period of time T1, the detection of time T2 since the finish of the detection of temperature, the output Po is gone to ''LOW''. The time T2 can be decided arbitrary. Thus, the reduction of power consumption can be possible during the air conditioner is in operation.

Title: Production of electroformed mold
Inventor: HOSOMI EIICHI
IPC: C25D1/10
Filed: 1987-02-24
Abstract: PURPOSE:To easily form fine rugged patterns on the surface of a mother mold even any complex shape of the pattern, by embossing a thermoplastic painted layer formed on the surface of a model body with a plastic film having fine rugged patterns, then executing chemical plating and electroplating on the embossed molded body, separating the plating layer only from the molded body and backing up the plating layer with rigid materials. CONSTITUTION:A thermoplastic painted layer 4b is formed on the surface of a model body 4a. The body 4a has a roundish curved surface between the spherical top whose radius of curvature is large and the circumferential surface. A prismatic plastic film 5 having fine uneven patterns 2' is heated and pressed against the surface of the model 4a to emboss the layer 4b. By this embossing, e.g., rhombic patterns 3a, 3b are formed on the curved top and circumferential surface of the model body. An electrically conductive film is formed on the outside of the resulting embossed layer and electroplating is rapidly carried out. After the electroplating, an electroplating layer formed on the electrically conductive film in one body is released together with the electrically conductive film and the released layer is worked to obtain an electroplating mold.

Title: Input device for character data
Inventor: YAMAZAKI SOICHI
IPC: G06F17/21
Filed: 1986-02-26
Abstract: PURPOSE:To eliminate the need for a special key and to simplify the input operation of character data by using a keyboard which outputs 8-unit codes for Roman characters and KANA (Japanese syllabary) and a converter which converts the KANA codes outputted from the keyboard into alphabet letters in terms of reading to perform Roman character/KANA conversion. CONSTITUTION:A Roman character/KANA conversion controller 22 compares the contents of an input buffer memory 21 with the contents of a Roman character/KANA conversion table memory 23 until data coincident with either one of those data stored in the memory 23 is inputted to the memory 21. When said coincident data is detected, the conversion data is loaded through the memory 23 and stored in an output buffer 24. The contents of the buffer 24 are outputted successively via an output changeover switch 25. This switch 25 functions to perform switching between validity and invalidity of the Roman character/KANA conversion. Thus the switch 25 is connected to the memory 24 in case the data received from a keyboard 1 is equal to KANA codes to validate the Roman character/KANA conversion. While the switch 25 is connected to the keyboard 1 if the data received from the keyboard 1 is not equal to the KANA codes. Then the Roman character/KANA conversion is invalidated.

Abstract: PURPOSE:To obtain an output signal whose picture image is thinned so as to express sufficiently the tone grade of picture elements of an original picture image by thinning in every small area including plural dots, i.e., in every unit of a mesh period. CONSTITUTION:A buffer 31 inputs an original picture data 311 and outputs a mesh picture signal 312. A dot counter 32 executes increment in every input of a clock signal 40 and counts up the number of dots in the line direction. A line direction small matrix number counter 33 executes increment in every period equal to the number of dots in the line direction of each small matrix area by the output from the counter to count up the number of small matrices in the line direction. A line counter 34 addes one (1) in every transmission of each line of the signal 312 to count up the number of lines. A line number counter 35 counts up the number of small matrices in the row direction. A gate circuit 36 inputs the signal 312 and outputs a signal 362 which is thinned in the unit of small matrix area by adding a thinning information signal 361 while being controlled by the outputs 321-351 of the counters 32-35.

Title: Arrangement structure of ice storage detecting device
Inventor: SAKAI TADASHI
IPC: F25C5/18
Filed: 1995-02-06
Abstract: PURPOSE: To improve the ice-making capacity, and to achieve the efficient operation of an ice-making mechanism or an ice-making part by arranging an ice storage detecting device only on the ice-making mechanism located farthest from an ice lump discharge port. CONSTITUTION: When the operation of a first ice-making unit 22 and a second ice-making unit 24 is repeated, and the ice lump of the prescribed amount is stored in an ice storage chamber 18, the operation of the ice-making units 22, 24 is stopped. Because an ice lump 20a is deviated from the middle position of the ice-making units 22, 24 to the second ice-making unit 24 side, the ice lump group below the second ice-making unit 24 is reduced in volume earlier, while a detecting plate 56 of an ice storage detecting device 54 of the first ice-making unit 22 keeps its condition being abutted on the ice lump group. When the consumption of the ice lump is advanced and the ice lump group below the first ice-making unit 22 is reduced in volume, the operation of the ice-making units 22, 24 is re-started. The ice-making unit is prevented from starting the ice-making and water-removing operation regardless of the state that a sufficient volume of ice lump is stored in the ice storage chamber 18.

This back scattered light is guided to an optical branch device 4 through the switch 2. The branch device 4 branches the light in two directions and one light beam is guided to a photodetecting element 6 through a filter 5 with wavelength for transmitting anti-Stokes light. The other light beam is guided to a photodetecting element 6' through a filter 5' with wavelength for transmitting Rayleigh scattered light. The outputs of those elements 6 and 6' are supplied to a comparator 7, which compares both intensity values to correct transmission loss which is not under the influence of temperature like the bending of the halfway path of the optical fiber 3.
