Title: Group iii nitride semiconductor light emitting element and fabrication thereof
Inventor: KOIKE MASAYOSHI
IPC: H01L33/06
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To obtain a spectrum close to pure blue by forming an emission layer of a group III nitride semiconductor containing at least indium and nitrogen but added with no impurity and carrying out short time heat treatment required for reformation of the emission layer thereby limiting the half width. SOLUTION: A sapphire substrate 1 is subjected to vapor phase etching and then a buffer layer 2 of AlN, an n-layer 3 of high concentration GaN, and a silicon doped n-layer 4 of Al0.08 Ga0.92 N are formed sequentially thereon. Subsequently, N2 , NH3 , TMG and TMI are fed at rates of 20 liter/min, 10 liter/min, 1.53×10<-4> mol/min and 0.02×10<-4> mol/min, respectively, for 6min to form an emission layer 5 of In0.08 Ga0.92 N. Finally, it is heated by an infrared lamp and held at 1140 deg.C for 5min before being quenched. Since no impurity is added to the emission layer 5 and high temperature heat treatment is carried out for a short time, the half width becomes as narrow as about 60nm in the case of emission peak wavelength of 540nm, and a spectrum close to pure blue can be obtained.

Title: Secondary-battery power unit, protective circuit, and method for protecting secondary battery from being abnormally charged
Inventor: HASEGAWA HIROYUKI
IPC: H02H7/18
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To prevent a secondary battery from being abnormally charged with a battery charger different from a specified battery charger. SOLUTION: When an abnormal voltage higher than a specific charging voltage is applied between input-output terminals 12 and 14, the abnormal voltage is supplied to the first input 312 of a first comparator circuit 310 which compares the voltage inputted to the input 312 with the first reference voltage 330 corresponding to the specific charging voltage. When the abnormal voltage detected as a result of comparison, an abnormality detecting signal is supplied to the latch circuit 440 of a switch control circuit 400. As a result, a control signal which turns off a switch 200 is sent from the latch circuit 440 and a charging path is turned off. When the abnormal voltage is continuously detected, the latch circuit 440 maintains the state and continuously turns off the switch 200.  When the abnormal voltage is canceled, a second comparator circuit 320 detects the cancellation and supplies a cancel signal to the control circuit 400. Therefore, the latch circuit 440 cancels the latch and the switch 200 is turned on, resulting in the chargeable state of a secondary battery 10.

Title: Thermal recording material
Inventor: HAKOMORI MASAKAZU
IPC: B41M5/28
Filed: 1990-08-10
Abstract: PURPOSE:To obtain a high-sensitive thermal recording material produced by directly providing a thermal color-forming layer on base paper by a method wherein a pulp in the base paper consists of a chemical pulp and an unbleached groundwood pulp, and a mixing ratio of the unbleached groundwood pulp and a thermal conductivity of the base paper by a laser flash method before the coating of a heat-sensitive liquid are specified. CONSTITUTION:An unbleached groundwood pulp and a chemical pulp are appropriately mixed for use. The unbleached groundwood pulp is produced by mechanically grinding a wood and is not subjected to a chemical treatment, such as bleaching. Therefore, most of lignin inherently contained in a wood remains in the pulp. It is required that a mixing ratio of the unbleached groundwood pulp is within the range of 30-80wt.% to the total amount of the chemical pulp and the unbleached groundwood pulp. If the unbleached groundwood pulp has a mixing ratio less than 30wt.%, a sufficient sensitivity improving effect cannot be expected. On the contrary, the mixing ratio is more than 80wt.%, the surface of the base paper is roughened and the strength is also lowered. To make a uniform film with a minimum thickness fluctuation as a thermal color-forming layer, the base paper is produced and smoothened for use by a machine calender. At this time, it is required that a thermal conductivity of the base paper by a laser flash method is 0.16W/m.K or less.

IPC: F02D41/12
Filed: 1989-08-17
Abstract: PURPOSE:To most suitably control the air-fuel ratio during decelerated operation by weighted-averaging the fuel supply quantities during decelerated operation to suppress the drop in the fuel supply quantity to correspond to the change in the intake air quantity, thereby preventing the airfuel ratio from becoming lean. CONSTITUTION:The fuel supply quantity is set by a means A based on the operating state of an engine. The decelerated operating state is then detected by a means B. Further, when the decelerated operating state is detected, the fuel supply quantity set the last time or the fuel supply quantity weighted averaged the last time, and the fuel supply quantity set this time are weighted and averaged by a means C with the data obtained the last time largely weighted. Based on the weighted averaged fuel supply quantity, a means D for supplying the fuel is driven-controlled by a means E. Thus, the air-fuel ratio during decelerated operation of an internal combustion engine with a supercharger can be controlled most suitably.

Title: Encoder of picture data
Inventor: HAGANUMA TOMOYUKI
IPC: H04N1/419
Filed: 1984-10-08
Abstract: PURPOSE:To encode picture data at a high speed in terms of a facsimile and picture file by outputting storage data of a storage means when a changing point can be detected in picture data of the prescribed bits by a detection means and out-putting run-length data from a conversion means when the changing point is not detected. CONSTITUTION:An encoder circuit 2 applies a window of six bits (six picture elements) with repsect to a picture data VD inputted from a scanner 1 and checks the data. When at least one changing point from black to white or white to black exists is six bits, a compression action for suppressing the redun dancy is not executed with respect to the data of six bits, which is encoded as non-compression data. On the other hand, when the changing point does exist in the six bits applied to the window, counting of data length continues, and the counted value up to the next changing point is encoded in terms of run length. This encoding is called a run length mode.

Title: Device for photochemical vapor deposition
Inventor: HIRAI YUTAKA
IPC: H01L31/08
Filed: 1984-10-11
Abstract: PURPOSE:To prevent the decline of a film forming velocity by making a light transmittance higher by providing the window formed in a reactor with a light focusing property. CONSTITUTION:A window 20 comprises a light focusing property. A material gas is introduced into a reactor 11 from a material gas introducing pipe 15 and high-energy beams B are projected from a beam source 17. The parallel beams B whose width is extended enter over the relatively wide region of the window 20 and are focused in the reactor 11. Then in the vicinity of the substrate (A) located near the focusing point, a light intensity becomes higher and a photochemical reaction of the material is carried out actively. Meanwhile, in the vicinity of the window 20, a light intensity is relatively weak so that a photochemical reaction does not progress. Consequently, a film is deposited only on the substrate (A) and not on the window 20 so that the light transmitting property of the window can be maintained well after a long-time use.
