Title: Film for lighting cover
Inventor: SATOU YUKIHISA
IPC: C08L67/00
Filed: 1981-09-17
Abstract: PURPOSE:To provide a film for lighting covers, which is capable of absorbing ultraviolet light and has an excellent mothproofing effect, by blending an ultraviolet-absorbing compd. with a plastic, and molding it into a film. CONSTITUTION:An ultraviolet light absorber or a polymer contg. an ultraviolet- absorbing functional group is blended with a plastic such as polyethylene tere- phthalate or a polycarbonate. The plastic is molded into a film to obtain the desired film for lighting covers, whose light transmittance in a wavelength region of 370mum or below is 5% or below. Examples of said ultraviolet light absorbers are 2,4-dihydroxybenzophenone and phenyl salicylate. Ultraviolet light absorbers of formulasIand II are peferred for polyethylene terephthalate. Since the resulting film does not transmit ultraviolet light within visible light wavelength region for insects, the activity of the insects can be greatly inhibited.

Title: Semiconductor memory device
Inventor: YAMADA TOSHIRO
IPC: H01L27/108
Filed: 1985-07-02
Abstract: PURPOSE:To enable higher integration by forming a deep groove under the separating region of a read-out MOS transistor, and forming a memory holding capacitor on the side of the groove. CONSTITUTION:A shallow separating region 22 electrically separates a side diffused layer 142 in a diffused layer 14 for storing signal charge, an upper surface diffused layer 144 and a MOS transistor channel portion. A stored signal charge in the layer 14 flows in the order of the layers 142, 146 and the layer 144, and read out to a bit line 30 through a transistor, a diffused layer 15 and a contacting portion 32. Since a deep separating region 20 electrically separates between two memory cells commonly having the contacting portion of adjacent memory cells toward the line 30, an insulating film of an SiO2 film is selectively buried. Thus, the area of a memory holding capacitor is increased for the area of the memory cell to increase the software error resistance of the memory cell.

Title: Improper timing detection circuit
Inventor: IZUMISAWA HIROYUKI
IPC: G06F11/00
Filed: 1978-11-27
Abstract: PURPOSE: To prevent a falut from spreading by immediately detecting the occurrence of improper timing of shorter intervals than preset proper timing, by coupling a delay element with synchronous flip-flops.  
     CONSTITUTION: This detection circuit consists of synchronous flip-flops 10 and 12, delay element 11 and exclusive OR circuit 13; input data to terminal D of each flip- flop are sampled by timing signal 100 to generate positive and negative outputs at  output terminals T and C respectively, delay element 11 generates information on  reference time for improper timing detection. Before time (t 0 ), flip-flops are reset  and at (t 0 ), and (t 1 ), flip-flops 10 and 12 change with the same polarity, so that  circuit 13 will generate no output. At (tE), however, flip-flops 10 and 12 generate  outputs of the opposite polarities by the delay element due to a noise and circuit 13  sends out an improper timing detection signal.

Title: Ink jet head
Inventor: SATAKE KENICHI
IPC: B41J2/045
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain an ink jet head forming a good image by sealing at least a piezoelectric film on a diaphragm with a flexible insulating sealing film thereby making uniform the ink ejection performance constantly. SOLUTION: Thickness of a sealing film 6 is preferably set in the range of 5-30 μm when it is composed of silicon resin, for example. If the thickness is less than that range, a piezoelectric film 3 can not be isolated from or protected against environmental fluctuation sufficiently. Consequently, the piezoelectric film 3 may be short-circuited or insulation thereof may deteriorate to cause malfunction of the piezoelectric film 3. If the thickness of the sealing film 6 exceeds that range, flexure deformation characteristics of the piezoelectric film 3 may be retarded to cause malfunction thereof. Since the piezoelectric film 3 has no possibility of short-circuit or deterioration of insulation, a good and uniform ink ejection performance is ensured constantly for each nozzle and a good image can be formed.

Title: Analog-digital converter
Inventor: HASHIKAWA KENZOU
IPC: H03M1/54
Filed: 1983-08-10
Abstract: PURPOSE:To prevent the stop of processing at the input of a negative voltage by providing a charging source charging a capacitor when the voltage of the charging capacitor is a prescribed value. CONSTITUTION:An input signal Vin inputted via a multiplexer 11 charges a capacitor C at the front edge of a conversion start signal STT from a CPU (not shown). Then a switch 15 is turned off at the rear edge of the start signal STT, a transistor (TR)13 is turned on and the capacitor C is discharged by a constant current IR. When the charging voltage attains to a prescribed voltage, an interruption signal STP is outputted to the CPU from a comparator 14 and the CPU obtains a digital value depending on the time from the start of charging to the interruption signal STP. Since the signal Vc is a prescribed voltage or below when the input signal Vin is a negative voltage, the comparator 19 is operated, a switch 18 is turned on and the capacitor C is charged, then the stop of processing to be caused by that no interruption signal is obtained does not occurs.

Title: Information recording and reproducing device
Inventor: NAKAHARA TAKASHI
IPC: G11B19/00
Filed: 1987-06-11
Abstract: PURPOSE:To enable the high density and stable recording and reproducing by providing an electrostatic eliminating means and/or an electrostatic preventing means on the moving path of an information recording medium. CONSTITUTION:Brushes 40 and 41 are disposed on the surface of an optical card 1 to be in contact with, and the brushes 40 and 41 are connected to an electrical ground formed of an electrically conductive material. Consequently, static electricity generated on the optical card 1 is dropped down to the electrical ground via the brushes 40 and 41 to reduce an electrostatic quantity charged in the optical card 1. For this, a dielectric effect on an actuator in an optical head provided closely to the optical card 1 is prevented so that the actuator can normally be operated. On the other hand, the optical card 1 is prevented from sticking dust, etc., in the air to its surface due to electrostatic attraction by lowering the electrostatic quantity charged in the optical card 1. By this method, the stabilized recording and reproducing can hence be carried out.

Filed: 1986-06-23
Abstract: PURPOSE:To stably expand the waveform of a video signal with a simple circuit constitution by using two kinds of diode characteristic to expand waveform distortions of the white part and the synchronizing signal part of the Video signal. CONSTITUTION:In case of the white part of the video signal inputted to the first transistor TR Q1, the first silicon diode DS is in the forward direction and a current flows to the first resistance R5. But the second germanium diode DG is in the reverse direction and the current does not flow to the second resis tance R6. In case of the synchronizing signal part, the diode DG is in the forward direction and the diode D3 is in the reverse direction, and the current flows to the resistance R6 but does not flow to the resistance R5. The emitter current of the TR Q1 is changed by values of diodes DS and DG and resistance R5 and R6 to change the amplification factor, thus expanding the white part and the synchronizing signal part of the video signal.

Title: Pitch extractor
Inventor: FUJII SHIGEKI
IPC: G10L25/90
Filed: 1988-06-16
Abstract: PURPOSE:To perform pitch extraction to only sound sections by first comparing inputted acoustic signals with a background noise level by means of a noise level deciding means so as to obtain signals indicating presence/absence of sounds. CONSTITUTION:Inputted acoustic signals are first digitized by means of an A/D converter 1 and inputted to a noise level deciding section 2 where the signals are held by a hold circuit 21 and used as a background noise level. Then the inputted acoustic signals are compared with the background noise level and whether or not no sound exists is outputted to a gate 3. When the level of the inputted acoustic signals is lower than 1.4 times of the background noise level, it is decided that no sound exists. When no sound exists, the gate 3 is turned off and no digital acoustic signal output is inputted to a multiplier circuit 5. As a result, a pitch extractor which outputs nothing when no sound exists and performs pitch extraction only when sounds exist can be obtained.
