Title: Light transmissible original projector
IPC: G03B27/54
Filed: 1992-03-31
Abstract: PURPOSE:To facilitate the operation of placing a light transmissible original on a proper position and also to restrain the occurrence of uneven illuminance by providing a light shielding mask means for controlling a reflective surface on the reflective surface of a light reflecting means. CONSTITUTION:The projector is provided with an original placing means, a light projecting means and a light reflecting means A.

Title: Magnetic recording medium
Inventor: ISHIHAMA HIROSHI
IPC: C09D5/23
Filed: 1990-03-28
Abstract: PURPOSE:To avoid wearing of cleaning sheet fibers and to improve reliability by incorporating two or more kinds of solid additives having different particle sizes by 2 - 30 wt.% in the magnetic material and specifying the solid additive of the largest particle size to have Mohs' hardness <=4. CONSTITUTION:Tow kinds of solid additives having different average particle sizes are used as the solid additive to be incorporated in the magnetic coating film. The solid additive of rather small particle size of 0.2 - 0.7mum consists of alumina (Al2O3) having >=5 Mohs' hardness, while the rather large particles of 0.5 - 1.5mum particle size is calcium carbonate (CaCO3) having <=4 Mohs' hardness. By this constitution, the solid additive of larger particle size directly comes into contact with a cleaning sheet during the magnetic disk is rotated, which reduces wearing of the cleaning sheet. Thus, the obtd. magnetic recording medium has high durability and reliability, causing no wearing of members which slide thereon.

Title: Integrated type semiconductor laser element
Inventor: ISHIKAWA MAKOTO
IPC: H01S5/00
Filed: 1991-03-15
Abstract: PURPOSE:To obtain a small-sized greenish blue laser light source which can be modulated at a high speed and has a high efficiency. CONSTITUTION:GaAS/AlGaAs quantum well type semiconductor lasers 2, 3, and 4 and slab type optical waveguides 5 and 6 composed of ZeSe/ZnS distorted superlattices are monolithically formed on the same n-GaAsl substrate through a coupling grating 7. In addition, a dielectric film 12 which highly reflects exciting oscillation light and another dielectric film 11 which highly reflects exciting oscillation light but does not well reflect second harmonics are respectively formed on the end faces of the light emitting and wavelength converting sections. When such constitution is used, the exciting oscillation light of the wavelength converting section is two-dimensionally enclosed not only in an optical waveguide, but also in the axial direction between both dielectric films 11 and 12 having high reflectivity. Such structure yields a high internal light density which is effective for high-efficiency generation of second harmonics. As a result, greenish blue laser light is efficiently obtained from the output-side dielectric film 11.

IPC: H01Q7/02
Filed: 1980-06-10
Abstract: PURPOSE:To store an antenna in a car body, by fitting elements which can be opened in loop to a support and providing a mechanism which locks the element to the support in spread open and folded state with the support. CONSTITUTION:An antenna main body 1 is drawn out from a cylindrical storage section 12 and it is locked by engaging the projection of a slide member 3 to a detaining hole 16. With this state, a support 2 is pressed down to detain the lower end of the support 2 to the engaging section of the lower end of the sliding member 3. Thus, elements 4a, 4b of loop shape are spread open and they are locked in usage state. In case of storage, the lower end of the support 2 is released from the engaging section to lift up the support 2. Thereafter, when the entire set is pressed down, the engagement of the detaining hole 16 is released and it can be stored in a cylindrical storage section 12.

Title: Reference voltage stabilization circuit for memory device
Inventor: CHIYOI HOON
IPC: G11C5/14
Filed: 1990-03-28
Abstract: PURPOSE: To output reference voltage kept at a fixed value even if temperature variation occurs by controlling a voltage value of an output side of a diode group so that voltage of an input side of a diode group is kept at a fixed value corresponding to variation of distributed voltage value fed back from a negative feedback section when reference voltage is varied. CONSTITUTION: This device has a negative feedback section 1 which distributes reference voltage applied to an output terminal and feeds back distributed voltage in accordance with a value of reference voltage to an output side of diode groups D1 , D2 . In this case, electric charges supplied from a power source voltage applying terminal VCC flow in the diode groups to some extent, while applied to an output terminal OUT. Then, as each of diodes D1 , D2 has the absolutely minimum voltage which must be applied for making a current flow to a forward direction, even if power source voltage is varied, a reference voltage value outputted to the output terminal OUT coincides with a total value of a statistic of threshold voltage of each of diodes D1 , D2 and voltage values of an output side of the diode groups.  Thereby, even if ambient temperature is varied and threshold voltage of each diode is varied, reference voltage coinciding with the total value is controlled at a fixed value.

Filed: 1990-03-27
Abstract: PURPOSE:To prevent electrical noise from being emanated to the outside by fixing a through capacitor to a guide rail case composed of conductive material and feeding power from an external power feeder through the through capacitor to a power supply board. CONSTITUTION:A guide rail case 6 is bored and a through capacitor 22 is inserted thus connecting a power supply board 5 with a feeder line 25.
