Title: Portable information processor
Inventor: SUZUKI MASASHI
IPC: G06F1/26
Filed: 1990-04-16
Abstract: PURPOSE:To reduce the power consumption of a power supply by providing a switch means to turn on and off the supply of power to a light source which irradiates a liquid crystal display means through its rear surface and selectively turning on and off the light source. CONSTITUTION:A switch means 7 turns on and off the supply of power to a light source 31 which irradiates a liquid crystal display means 2 through its rear surface. Then the power supplied to the source 31 from a power supply via the means 7 is cut when the irradiation is not required to the means 2, e.g., when the display is satisfactorily recognized through the means 2. As a result, the power consumption of the power supply is reduced and a period during which an accumulator is charged is increased. Thus the working time of a portable information processor can be increased.
Patent JP-H11298157-A (JP)
Title: Electronic device
Inventor: KANO TOMOHISA
IPC: H05K5/02
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To suppress transmission of an shock stress of an electronic device when fell to electronic part units built in the device to thereby enhance an anti-shock resistance of the device. SOLUTION: The electronic device can have its anti-shock structure by means of resilience of resilient buffering members 12 and 15 abutted against electronic part units such as a liquid crystal display part weak in shock in its all directions. This causes a shock stress applied to the electronic part unit in the falling shock to be converted to a deformation energy of the buffering members 12 and 15, thus lightening the shock stress applied to the unit. Further, a special shape of the lower buffering member 12 enables the resilience of the buffering member to be secured even at low temperatures, thus increasing an anti-shock ability at low temperatures.  Further, a sheet 11 disposed between the unit and buffering member 12 enables reduction of a friction resistance between the liquid crystal display and buffering member 12, and fast restoration of the buffering member to its original shape after shocked and deformed. Thereby since a display area of the liquid crystal display is also returned naturally to a visual range, user's work will not be prevented.

Title: Optical head and its manufacture
Inventor: HINO YASUMORI
IPC: G11B7/1381
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To reproduce an optical disk of high density in an optical head super resolution reproduction system by selectively passing only a part adjacent to the center of convergent light by providing a filter formed and positioned easily and highly accurately by light of a reproducing optical system in the vicinity of a light converging point of the reproducing optical system. SOLUTION: Reflected light from an optical disk medium is incident upon a reproducing optical system through a condenser lens 107. A condenser surface of the condenser lens 107 is separated from an incident surface by a length equivalent to a focal distance and on the condenser surface a Ti thin film 108 having about 100 mm thickness is formed by a spattering method. A light beam from a light source 113 is made to a parallel beam by a lens 114 and is incident upon the condenser lens 107. When the Ti thin film 108 is brought into a focus, the Ti thin film 108 is melted in this focus position to form a pin hole area 108a. Consequently, a pin hole filter 108 for passing only a central part of the light beam is formed on the condenser surface by the light passed actually through the reproducing optical system and hence reproducing resolution is enhanced.
