Patent JP-H0954241-A (JP)
Title: Light projecting circuit
Inventor: SHIMURA YOSHIHIKO
IPC: G02B7/32
Filed: 1995-08-16
Abstract: PROBLEM TO BE SOLVED: To obviate the deterioration and failure in the performance of a light emitting element. SOLUTION: Excess current is bypassed by an NPN transistor 12 at the time when the current IF flowing in the light emitting element 11 tends to increase to its rating or above. Then, the excessive current-component exceeding the rating flowing in the light emitting element 11 is bypassed even when a battery, such as a brand new high-performance battery, having high voltage is used in the case where the current to be passed to the light emitting element 11 is set low in such a manner that a sufficient light quantity is obtd. even with the low-voltage battery just before a battery end and, therefore, the current flowing in the light emitting element 11 is so controlled as not to exceed its rating. The deterioration and failure of the light emitting element 11 are thus prevented.

IPC: H01L31/02
Filed: 1988-09-14
Abstract: PURPOSE:To form a photo-semiconductor module with good producibility and good precision by forming Cu plating films on those portions of holder flange end face except perimeters and those portions of holder mounting surface of photo-semiconductor element/lens assembly other than perimeters, performing welding after optical axis alignment in the condition that the holder is pressed to the element/lens assembly and Cu plating films are pressed together.

Title: Thin electronic equipment
Inventor: ASAMI YOSHIAKI
IPC: G06F15/02
Filed: 1988-09-14
Abstract: PURPOSE:To prevent the trouble of a mounted circuit substrate, the internal short circuit of a power supply battery, etc., by forming an information recording part on the outer surface of at least one of two sheets corresponding at least to a part of a battery insulated seal-up body. CONSTITUTION:An information recording part is formed on the outer surface of at least one of two sheets 31 and 35 corresponding at least to an insulated seal-up body 47 of a battery 46. Thus the pressing force, if generated with pressure applied to both sheets 32 and 35 via the information recording part at application, etc., is applied to the body 47 of an intensive flat battery 33. Thus the pressing force applied directly to a circuit substrate 32, the battery 33, etc., set in an electronic equipment can be evaded. Furthermore the force applied to the generating element 46 of the battery 33 can be reduced even though the information recording part is partly positioned on the element 46 since the pressing force is received at the side of the body 47. Thus it is possible to avoid the trouble of the substrate 32 and the internal short circuit of the battery 33 and to obtain a stable and multi-purpose thin electronic equipment.

Filed: 1993-09-17
Abstract: PURPOSE:To take a measurement with accuracy enough to control reducing liquid by adding alkali to titrated liquid so as to keep the pH value of the liquid for alkalinity, even at the end point of titration. CONSTITUTION:The prescribed amount of sample is taken from a water solution as a measurement object, and an iodine solution is used as titrating liquid in the presence of alkali enough to keep the pH value of titrated liquid for alkalinity from the beginning of a titrating operation to the end thereof, thereby measuring a potential difference for oxidation reduction. In this case, a reducer for measurement is a boron hydroxide (for example, boron hydroxide sodium or derivative thereof) or hydrazine or sulfuric acid hydroxyl ammonium, or the derivative thereof. In order to keep the alkalinity of the titrated liquid, the pH value thereof is preferably kept between 11 and 13. For this purpose, alkaline metal hydroxide (for example, sodium hydroxide) is preferably added to the titrated liquid. A titration end point is preferably taken at the potential where an oxidation reduction potential difference is between +200mV and +350mV for a reference electrode. Concentration is calculated from a titrated amount at the end point.

Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To prevent a passenger from 'rushing' to get on a train, to secure safety, and to prevent the time delay by limiting a door reopening/closing action implemented in detecting a door to catch a passenger to either one of double opening door. SOLUTION: A pressure air pipe from a reopening/closing circuit 7 to for example, a right door drive cylinder is eliminated so that only a left door drive cylinder 3L is operated by a detection input signal from a catch detecting part 4, and it is so constituted that only the left door 2L is reopened/closed. When the 'catching' state is detected, only the left door 2L is temporarily opened. Compared with the general double opening type, the maximum opening width becomes 1/2 and the 1/2 of the widely opened getting-in/off time or more is lost so as to prevent a passenger from 'rushing to get on a train' newly, secure the safety, and prevent the delay of an operation time.
