Title: Forming method of semiconductor ctystallized film
Inventor: YAMAGUCHI NORITOSHI
IPC: H01L29/786
Filed: 1990-05-30
Abstract: PURPOSE:To crystallize a semiconductor film formed on such a substrate as having properties of synthetic resin, by crystallizing a semiconductor layer with a metal layer interlaid on the ground layer of the semiconductor layer. CONSTITUTION:A ground layer 2 is formed on a substrate 1. This ground layer 2 is made up of a first insulating film 2a, a metal layer 2b, a second insulating film 2c and the like. On this ground layer 2, an amorphous or polycrystalline semiconductor layer 3 is formed. Next, a protecting film 4 is formed on the amorphous or polycrystalline semiconductor film 3. By applying a laser light L from above the aforesaid protecting film 4, moreover, the amorphous or polycrystalline semiconductor film 3 is crystallized, so that a crystallized film be formed. On the occasion, it is unnecessary to melt the whole of the amorphous or polycrystalline semiconductor film 3 in the direction of the thickness, and it is crystallized with the lower layer part thereof left uncrystallized. The heat generated when a laser beam is applied to the semiconductor layer is radiated from the metal layer in the ground layer, and therefore such a substance of relatively inferior heat resistance as having properties of synthetic resin can be used also as the substrate.

Title: Photomask
Inventor: ARAIHARA SATOSHI
IPC: G03F1/40
Filed: 1988-06-08
Abstract: PURPOSE:To prevent a light shield film pattern from being broken owing to charged-up static electricity by constituting a conductive film area surrounding a light shield film area as one continuous area. CONSTITUTION:A chromium film 2 on a glass substrate 1 forms the continuous conductive area surrounding the light shield area so that eight corner areas among P11-P57 have corners cut. Thus, the large conductive area is formed to evade discharge even in the case of a charge-up state, so the pattern is not broken. When the chromium film is left in the continuous state, the chromium film 2 is formed on the transparent glass substrate 1 and a positive resist film 3 is formed thereupon; and the periphery is coated with a protective film 4 formed by blackening a polyvinyl-alcohol solution with dye and then exposed, so that the resist below the protective film 4 is not exposed and left as a mask. Consequently, the chromium film at the periphery can be left.

Title: Valve stem sealing device
Inventor: YAMANAKA SHINICHI
IPC: F01M9/10
Filed: 1994-06-01
Abstract: PURPOSE:To prevent seizure and wear due to lack of oil by fitting the base end part of a valve stem seal to the outer circumference of a valve stem, and forcing oil to flow in/out in relation to the inside of a chamber formed by the valve stem seal. CONSTITUTION:The base end part 5 of a valve stem seal 3 is fitted to be fixed to a valve stem 2 which is loosely fitted to a valve stem guide 1 and reciprocated in a vertical direction by the rotation of a camshaft 20 so that the lip part 6 of the valve stem seal 3 is in contact with the outer circumference of the valve stem guide 1. Hereby, capacity inside a chamber 7 formed by the valve stem seal 3 is increased when the valve stem 2 ascends so as to generate negative pressure inside the chamber 7, therefore oil flows into the chamber 7 through a through-hole 8. While, the oil inside the chamber 7 is fed under pressure to an oil pool 11 through a spiral groove 10 provided to the inner circumferential part of the valve stem guide 1 because the inside of the chamber 7 becomes positive pressure when the valve stem 2 descends.

IPC: G03G15/10
Filed: 1978-11-17
Abstract: PURPOSE: To prevent uneven development and transfer pass-through by making dull the angles of the lower corner parts of the pressure-regulating-plate-mounting parts to the casing side walls in a developing head.  
     CONSTITUTION: The pressure-regulating plate consists of two plate parts 12, 13 protruding both side walls 8A, 8B of the developing head casing and the angles of the respective corner parts P 1  in the joint positions of these both pressure-regulating plates 12, 13 and side walls 8A, 8B become dull. Since the air therein goes out at the initial period of the effluence of the developer, there is no chance for the air bubble to stagnate there. Similarly, the corner parts P 2 , P 3  of the upper side plate 8C of the casing and the respective side walls 8A, 8B are also formed obtuse angles to prevent the stagnation of air bubble. The foregoing obtuse angles are suitably made 100°W160°. These enable the uneven development and transfer pass-through occuring in bubbles to be prevented.

Title: Informaton recording device of tape recorder
Inventor: NAGATA YOSHINOSUKE
IPC: G11B5/027
Filed: 1977-11-24
Abstract: PURPOSE: To increase the recording amount per unit length of tape without deteriorating the quality of sound signal, by time processing the audio signal in delay circuit, and controlling the tape drive with the circuit to detect presence or absence of sound, monomultivibrator and OR circuit.  
     CONSTITUTION: A delay circuit 3 delays the audio input signal applied to a terminal 1 by delay time ΔT, and supplies it to the recording head of a tape recorder 2. A sound detecting circuit 4 detects presence or absence of said audio input signal. A monostable multi circuit 5 is triggered when the output-present state of the detecting circuit 4 is converted to the output-absent state, and outputs a pulse signal of a certain pulse width T. An OR circuit 6 receives the output from said monostable multi circuit 5 or from detecting circuit 4, and controls the tape drive of the tape recorder 2. The pulse width T of pulse signal of the monostable multi circuit 5 is set larger than the sound delay time ΔT of the delay circuit 3. As a result, the tape is driven while the audio signal exists, and is stopped when there is no audio signal. On the other hand, the tape is driven for a period of pulse width T after the audio signal is cut off, and stops Δt time later.
