Inventor: UMEHARA MASAAKI
IPC: G11B7/12
Filed: 1983-05-27
Abstract: PURPOSE:To obtain a writing and reading-out method of an optical information recording medium which has high sensitivity and withstands reading-out light by writing the information on an optical information recording medium having an org. dye recording layer exhibiting a metallic light-reflecting characteristic on a base plate with the light of the wavelength having higher optical absorption of the recording layer and reading out the same with the light of the wavelength having higher light reflectivity of the recording layer. CONSTITUTION:Information is written by the light of the wavelength having higher optical absorption on an optical information recording medium having an org. dye recording layer exhibiting a metallic light-reflecting characteristic on a base plate and the information is read out by the light of the wavelength having the higher light reflectivity. Any org. dye is usable as the dye for forming the recording layer as far as said dye exhibits a metallic light-reflecting characteristic. The dye which provides the metal-like reflection, that is, bronze brightness, exhibited in a specific light wavelength region and which has >=20%, more preferably 30% reflectivity to the laser wavelength used for writing and readingout is preferable in actuality. The org. dye is exemplified by a cyanine dye and merocyanine dye.

Filed: 1988-04-14
Abstract: PURPOSE:To surely send information by informing an unarrived notice not only to a sender terminal equipment but also to a sender in voice and informing the name of the sender in case of unarrival notice. CONSTITUTION:In case of unabled delivery regardless of repetitive recalling, a CPU 101 regards it as unarrived delivery, a retrieved name 202 and a time stored in a text storage file memory 105 are converted into a voice signal by a voice synthesizer 104 and the signal is synthesized together with a message representing an unarrived notice in the inside of the voice synthesizer 104. The CPU 104 uses a caller telephone number to dials it through a voice line control section 106 to send the message synthesized by the voice synthesizer 104. The message is sent from a telephone set 112 through a voice line 111. Then the number of a calling terminal equipment and a 1st page of the unarrived text are sent from the text storage file memory 105 to a facsimile terminal equipment 103 as to which text is unarrived among texts through a facsimile line controller 102. Thus, the notice is surely sent.

The electron- acceptive compound in the recording material is preferably used in an amount of 50-5000wt.% based on the colorless dye, and the salicylic acid derivative preferably constitutes at least 10wt.% of the electron-acceptive compound. When these are applied to the recording material, they are used in the form of a finely dispersed material, minute droplets or a film. By this, a recording material can be obtained which is formed of materials favorable in color forming properties and the stability of developed color images and satisfying other required conditions.

Title: Battery power device and battery case
Inventor: TANAKA KUNIAKI
IPC: H02J7/00
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To prevent heating of batteries and the leaking of liquid even if new and old batteries are used in combination. SOLUTION: In Figure (A), a battery power device has rated 1.5 V batteries 1-4, the batteries 1, 3 being connected in parallel with the batteries 2, 4, and the pairs of batteries being connected in series with each other. In the case of such a connection, even if the battery 4, for example, is an old battery whose voltage has been decreased, a voltage applied to the battery 4 from the battery 2 does not become 1.5 V or more, so that even if a current in the direction of the arrow in the figure flows from the battery 2 to the battery 4, the battery 4 is not overcharged to prevent heating of the battery 4 and the leaking of liquid. Such a connection is more effective if the batteries 1-4 are alkaline batteries which are small in internal resistance. Battery power devices having connections shown in Figure (B), (C) can produce similar effects.

Abstract: PURPOSE:To reduce leakage currents by turning a channel layer and an anode layer upside down and preventing an effect on a barrier layer having a wide band gap of an impurity in source-drain layers. CONSTITUTION:An anode layer 6 and a channel layer 2 are turned upside down to conventional structure. That is, structure in which the channel layer (a first semiconductor layer) 2 containing no impurity or having low impurity concentration, a barrier layer (a second semiconductor layer) 5 similarly containing no impurity or having low impurity concentration and the fixed conductivity type anode layer (a third semiconductor layer) 6 are laminated onto a substrate 1 in the order is formed.

Title: Detector for surface defect
Inventor: IKEKI YOSHIKAZU
IPC: G01N21/93
Filed: 1985-04-30
Abstract: PURPOSE:To detect a defect at an end part by providing an optical transmitting/ photodetecting head and a photodetecting head across a body to be detected, detecting both end positions of the object body with the output of the photodetecting head and using the detection output as a reference signal, and comparing it with the output of reflected light. CONSTITUTION:The optical transmitting/photodetecting head 1 and photodetecting head 4 are provided across the body 3 to be detected. Then when there is a defect at an end part of the detected surface of the object 3, regular reflected light phi2 photodetected by the head 1 rises before the detected surface is scanned completely, and consequently the falling period of a measurement signal (C) obtained by a photoelectric element is made early. The rising period of incident light phi4 to the head 4 is constant regardless of the defect, so the falling period of a measurement signal E obtained from a photoelectric element 4 is also constant. Consequently, the pulse width (T2') of the 2nd pulse (P2') generated when both signals C and E fall is wider than original pulse width (T2). Therefore, the defect at the end part is detected by detecting the time difference (T1) in the rising of the signal C and the original pulse width T2 being larger than settings.
