Title: Storage device
Inventor: SEKINE SHIGEO
IPC: G11B33/04
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To effectively utilize a vacant space on the back surface of a bezel so as to house a medium such as an optical disk, etc., by equipping the bezel fixed to a drive main body and a holder, with its front end, fixed to this bezel. SOLUTION: The holder 22 opened in its upper part is mounted on the drive main body 8, and a front end part of the holder 22 is fixed to the bezel 14A. The inside of the holder 22 is communicated with a slot 18. Thus, since the holder 22 is provided in a vacant space behind the bezel 14A, a removable medium such as an optical disk cartridge 24, etc., can be housed via the slot 18 into the holder 22. The dimensions of the holder 22 and the slot 18 are set so as to correspond to the cartridge size to be housable. Notches 18a and 18b are formed in approximately the middle part of the slot 18, and the removable medium inside the holder 22 can be taken out by inserting fingers into these notches. Consequently, the removable medium can be stored by utilizing the vacant space.

IPC: F23N5/08
Filed: 1991-07-16
Abstract: PURPOSE:To obtain the title apparatus for an ultraviolet ray discharge tube (UV tube), which apparatus quantitatively detects the sensibility to ultraviolet rays discharged from the UV tube and can diagnose the trouble of the UV tube. CONSTITUTION:High voltage at point A is periodically switched by an astable oscillation circuit 11, a monostable oscillation circuit 13, transistors 12, 14, etc., and is applied to a UV tube 1. At this time, a discharge pulse is generated by the UV tube 1, and is converted to voltage by a F/V converter 16. On the basis of this voltage, the UV tube 1 is diagnosed by a trouble-diagnosing circuit 17. Since the sensibility of the UV tube can be quantitatively detected as analog value, the state of trouble and deterioration of the UV tube can be accurately diagnosed thereby. At the same time, for example, the sensibility of a flame relay can be easily regulated by regulating reference voltage for a comparator.

Title: Burner
Inventor: SUGIYAMA SHUNICHI
IPC: F23D14/24
Filed: 1985-09-10
Abstract: PURPOSE:To enable burning always in stable condition even when fuel input is in a wide range by controlling a quantity of plasma injected into air, fuel, and their mixture. CONSTITUTION:A burner is attached to a burner tile 1 and a tube-shaped fuel injection part 3 is placed around a tube-shaped plasma injection device 2, and further a tube-shaped air injection part 4 is installed around the fuel tube 3 and the burner is constituted in a triple tube structure. Control of plasma quantity is made by controlling the intensity of input electric voltage on the basis of the detected quantity found out from burner load and fuel flow rate. Plasma has such function as to activate fuel and flammability is improved corresponding to plasma injected quantity. When load increases, fuel flow rate also increases and flow velocity of a mixture is more faster than that of burning velocity and then blow-out of fire flame often occurs, however, when burning velocity is increased by injection of plasma, burning velocity and flow rate of the mixture are well-balanced to attain stable burning.

Title: Pll circuit
Inventor: YOSHIZAWA AKIHIKO
IPC: H03L7/08
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To obtain an output with a small conversion coefficient of a VCO, a low jitter and high stability even when a multiplication is as large as a multiple of several hundreds with respect to a reference frequency. SOLUTION: A divide-by-M frequency divider 4a divides an output frequency Fout to provide an output of a frequency Fout/M. A phase comparator (PFD) 1 detects a phase difference between the frequency Fout/M and a reference frequency Fref and provides an output of an error signal in response to the phase difference. A low pass filter 2 integrates the error signal outputted by the phase comparator 1. The integrated error signal is given to a voltage controlled oscillator VCO 3 as a control voltage. The voltage controlled oscillator 3 provides an output of a desired oscillating frequency Fout/N. An N multiplier circuit 6 multiplies the oscillating frequency Fout/N by N to output the desired output frequency Fout.

Title: Optical fiber, optical fiber protector and
Inventor: JIYOOJI TEII PINSON
IPC: G02B6/44
Filed: 1989-08-01
Abstract: PURPOSE: To make it possible to protect an optical fiber against the damage by a laser in the case a laser beam falls onto the optical fiber for a long period of time by providing the fiber with a laser of an expansion material which insulates the optical fiber against the thermal damage by reacting at the heat input level of the incident laser beam. CONSTITUTION: The optical fiber 30 includes a central core 32 and a cover layer 34 enclosing the same. The core 32 and the cover layer 34 consist of glass type materials. The cover layer 34 is formed of a glass material having the refractive index lower than the refractive index of the core 32. In such a case, the optical fiber has the expansion material 38. The expansion material is a material having the nature that the material is flexible at the beginning and reacts to create a foamed or insulated layer when heated. These materials expand considerably in their volume to impart a direct thermal insulating layer for protecting the cover layer 34 and the core 32. As a result, the breakage or damage of the optical fiber by receiving the beam of the highenergy laser is prevented.

Title: Semiconductor laser and manufacture of the same
Inventor: HIUGA SUSUMU
IPC: H01S5/00
Filed: 1985-09-12
Abstract: PURPOSE:To obtain a laser beam of excellent quality in a multiple integrated semiconductor laser by a method wherein material of the layer in the oscillated light distribution region is made to be different according to either side of stripes parallel to a junction plane by the use of melting back through liquid phase crystal growth. CONSTITUTION:A layer 9 between dual stripes 8 is easier to be melted back than layers 5 outside the dual stripe 8. This property, which is a property of a liquid phase crystal growth, is utilized to eliminate the absorbing layer between the stripes 8 by melting back and an absorption loss is reduced. Therefore, a weak point that a first degree mode whose electric field stress becomes zero in this part is easy to appear is eliminated. On the other hand, the absorbing layers 5 still remain outside the stripes 8 and hence the light is absorbed and a loss is large. Therefore, the first degree mode whose electric field stress is large in these parts in difficult to appear because the loss is large as a whole. As a result, the semiconductor laser of the present inventional can bear a zero degree mode only.

Abstract: PURPOSE:To enable easy working of an ultrafine pattern by forming the magnetization of the fine pattern on a thin vertical magnetization film formed on a base plate and sticking and fixing the magnetic particles coated with a high polymer material to the thin film thereby patterning the film. CONSTITUTION:A thin film 2 having high magnetic permeability is laminated on a base plate 1 and further a thin vertical magnetization film 3 is laminated by a method, such as sputtering, on the film 2, thereby forming a medium 6. Magnetization of a grating pattern is formed at a micro pitch P, for example, 0.5mum, on the thin film 3. Magnetic writing by a vertical magnetic head is used for forming the grating pattern.
