Title: Magnetic disk device
Inventor: WAKATSUKI KOSAKU
IPC: G11B33/14
Filed: 1992-01-08
Abstract: PURPOSE:To prevent adherence to a magnetic head slider and damage to a magnetic disk by providing a dust collection means ahead of or behind the magnetic head slider on the inflow side of the magnetic disk to trap dust by an electrostatic force. CONSTITUTION:A magnetic head slider 2 supported on a support spring structural body 3 is arranged as opposed to a magnetic disk 1 and a dust collection means 4 is provided ahead of the slider 2 on the inflow side of the disk. The means 4 performs a dust collection by an electrostatic force to trap any possible dust existing between the slider 2 and the disk 1. When the slider 2 lifts without contacting the disk 1, the means 4 is provided in front of the slider, and when the head 2 impacts the disk 1. the means 4 is arranged behind the head. This enables the trapping any possible dust existing between the magnetic disk and the magnetic head slider and any dust adhering to the magnetic head slider thereby preventing damage to the magnetic disk as caused by the dust.

Title: Flash lamp
Inventor: NAKAO SUMITO
IPC: F21K5/04
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To solve problems caused by the peeling or falling of an igniting material by using a firing material made of a flammable metal which catches fire by carrying current and directly igniting a luminescent material without using the igniting material of a chemical material. SOLUTION: A firing material 4 of flammable fine wires made of one kind of metal selected from zirconium, aluminum, hafnium and the like or an alloy of at least two of these metals is connected to inner lead wires 3, 3. A luminescent material 5 is formed and used by sealing one kind of metal fine wires of zirconium, aluminum, hafnium and the like or at least two of them by the weight corresponding to the amount of luminous energy in a glass bulb 1. When current is carried to the firing material 4 through a base part 4, the inner lead wires 3, 3, the firing material 4 catches fire, the luminescent material 5 ignites, consumes oxygen to instantly burns, and emits light to the outside of the bulb 1. Since an igniting material is not used differently from the conventional flash lamp, problems caused by peeling or falling of the igniting material is completely solved.

A position of the parts 10 is measured by a recognizing device based on an image of the camera 4, and the parts 10 is mounted on the board 11. A measurement surface is thereby positioned in the position A even if the thickness of the parts 10 differs; therefore, magnification of an image is always constant and parts can be mounted accurately without measurement errors.

Title: Telephone automatic response device using sound synthesizing circuit
Inventor: HASHIMOTO KAZUHASU
IPC: H04M1/65
Filed: 1982-01-11
Abstract: PURPOSE:To attain small size, light weight and manpower saving, by using a voice synthesizer for the generation of a response message and omitting a tape and its driving mechanism. CONSTITUTION:When a call signal is given to telephone lines L1, L2, an output of an H level is produced from a ringing amplifier 1, transistors (TRs) TR-2 and TR-3 are turned on and a relay Y-1 is energized. Thus, contacts y1-1-y1-4 are closed. When the call signal stops ringing, the output of the amplifier 1 is annihilated, but the relay Y-1 is held. Further, since an output of the inverter of a sound synthesizing circuit 2 is H before a timer circuit 5 is time-off, the address A1 of the circuit 2 is H and a synthesized sound corresponding to the address A1 is outputted from a terminal OUT of the circuit 2. When a caller hooks off the telephone set before the timer 5 is time-out, the TR-1 is turned on with a pulse generated on the lines. Thus, the relay Y-1 is restored.
