Title: Optical writing unit
Inventor: IKEDA YOSHITO
IPC: H01S5/40
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To drive an LD array for use in an optical writing unit by using a general purpose LD drive control circuit (semiconductor laser drive control means). SOLUTION: A GAVD 11 (output timing determining means) delivers an SW switching signal to any one of switches SW 66-69 in a switching circuit 65 (switching means). Upon elapsing a time at least corresponding to the operation delay time of the switch SW after delivering the SW switching signal, an APC signal (control start signal) is delivered to the APC control section 62 (current control means) of an LD drive control circuit 60 (semiconductor laser drive control means) connected with a negative feedback loop formed through switching operation of the switch SW. Upon finishing APC operation through the APC control section 62 of the LD drive control circuit 60 connected with a negative feedback loop formed through switching operation of the switch SW, delivery of the SW switching signal to the switch SW is stopped.

Title: Optical recording medium
Inventor: KURODA MIKIYA
IPC: G11B7/24
Filed: 1989-12-27
Abstract: PURPOSE:To enlarge the allowance of an attenuation coefft. of an optical layer and to enable use of various kinds of materials by forming each specified optical recording layer, light-reflecting layer and interferential layer to constitute the medium. CONSTITUTION:An optical recording layer 2 is formed on a substrate 1, on which an interference layer 3 is formed. The attenuation coefft. of the optical recording layer 2 is made <0.5 for the wavelength of reproducing light, and the attenuation coefft. of the interference layer 3 is made <=0.05 for the wavelength of reproducing light. Further a light-reflecting layer 4 is formed on the interference layer 3 so that the reflectance of the reflecting layer 4 is >=90 % for the wavelength of reproducing light. A protective layer 5 is formed on the light-reflecting layer 4. Therefore, the interference layer 3 increases the reflectance of the medium itself. Thereby, the allowance for the attenuation coefft. of the optical recording layer 2 is widened, which enables use of various kinds of materials.

Title: Still picture television telephone set
Inventor: TEJIMA AKIRA
IPC: H04N1/00
Filed: 1989-12-28
Abstract: PURPOSE:To prevent consecutive reception of a disturbed picture signal by informing the reception state of a receiver side to a sender side and sending the picture signal sent at a preceding time again from the sender when a picture error takes place. CONSTITUTION:When a sender side receives an NAK signal representing occurrence of a picture error as control information 12 through the transmission operation, the sender sends again a same picture signal (in this case, an odd number field 14) as a picture signal sent precedingly and a receiver side enters the reception mode of receiving the odd number field 14. when the sender side receives an ACK signal representing the normal reception as control information 12 conversely, the sender side sends an even number field 15 and the receiver side enters the mode of receiving the even number field 15 in matching therewith. The reception state is informed to the sender side in this way for each block of the picture signal (even number and odd number fields) and the sender side makes transmission in matching therewith, even when an error such as a picture error takes place, the normal picture is received by the retrial of the transmission.

Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method in which a liquid crystal driving board can be inspected with good accuracy, by a method wherein a low-frequency component is removed from an image signal obtained from reflected light from a dielectric reflecting film, and a binarization processing operation is performed. SOLUTION: Many pixel electrodes a2 are installed in a matrix shape on a liquid crystal driving board A. A modulator 1 is formed in such a way that a thin-film transparent electrode 1b is pasted on one face of a liquid crystal sheet 1a and that a semiconductor reflecting film 1c is vapor-deposited or pasted on the other face. The semiconductor reflecting film 1c is faced downward so as to be fixed to an inspection apparatus body. The liquid crystal driving board A is arranged so as to be faced by keeping a very small gap Δd in the lower part. A prescribed voltage is supplied to the pixel electrodes a2 and the transparent electrode 1b from a power-supply device 10. The modulator 1 is irradiated with light from a light source 4 via a beam splitter 3, a filter 5 and a lens 6. A reflected image from the semiconductor reflecting film 1c is photographed by a CCD camera 7.  An image processor 8 removes a low-frequency component containing a DC component from its image signal so as to perform a binarization processing operation. A defective pixel electrode is detected, and its result is outputted to a monitor 9.

Title: Gas detector
Inventor: NAGAI HARUO
IPC: G01N21/39
Filed: 1989-12-29
Abstract: PURPOSE:To improve the accuracy of controlling wavelengths and outputs by causing the adequate laser driving currents corresponding to respective wavelengths to flow to a semiconductor laser to be used for a light source, thereby easily controlling the wavelengths in such a manner that the output components of the two wavelengths are equaled. CONSTITUTION:The semiconductor laser 1 alternately emits the wavelength lambda1 which is liable to be absorbed in methane and the wavelength lambda2 which is hardly absorbed in the methane in an equal intensity according to driving currents I1, I2 from a current driving section 2. A red light laser 3 is used as a guide for indicating the exit direction of the laser beam of the laser 1. The laser beams emitted from these lasers are multiplexed by a mirror 4 and a half mirror 5 and are projected by mirrors 6, 7 into the atmosphere. The laser beams of wavelengths lambda1, lambda2 projected into the atmosphere are scattered by a road, wall, etc. The scattered laser beams are condensed by a Cassegrain type condenser mirror 8 and the light signal thereof is converted to an electric signal by a photodetector 9. The electric signal level is detected in a signal processing section 10. Whether there is methane in the atmosphere or not is thus detected.
