Title: Photosensitive composition
Inventor: KURIYAMA SATOSHI
IPC: C09B11/00
Filed: 1983-05-12
Abstract: PURPOSE:To obtain a uniform yellow-orange picture image having a stable color density for a long time by incorporating a specified compd. and alpha-diketone in the compsn. CONSTITUTION:[Bis(4-hydroxyphenyl)-(4-phosphonoylphenyl)]methane (BHPM) expressed by the formula (wherein R1<1> is 1-18C alkyl, 2-18C alkenyl, aryl, or aralkyl; R2<2> and R3<3> are 1-18C alkyl, 2-18C alkenyl, aryl, or aralkyl), which develops color by the irradiation with the light having specified wavelength L1, is incorporated together with alpha-diketone into the compsn. The compds. are used together with a binder and a solvent for coating a base material. An image is formed by irradiating the coated film with the light having, for example, 200- 350mmu wavelength through a pattern. When further the image is irradiated with the light having a wavelength L2, BHPM doesnot develops color due to the effect of alpha-diketone for inhibiting color development. Thus, an image having a stable background is obtd. If the coated film is first irradiated with the light having the wavelength L2 through a pattern, BHPM is inactivated to form a latent image, then the image develops color by the irradiation with the light having the wavelength L1. By this way, both negative and positive picture images are obtainable and the stability of the obtd. picture images is superior.

Title: Paste type cadmium negative electrode
Inventor: KAIYA HIDEO
IPC: H01M4/26
Filed: 1988-04-06
Abstract: PURPOSE:To enhance self-discharge characteristics in a cadmium negative elec trode comprising a conductive core material coated with a paste active material mainly containing a cadmium oxide, a cadmium hydroxide or metal cadmium by causing the paste active material to contain a sulfonated polymer as a bonding agent. CONSTITUTION:A sulfonated polymer forms -SO3H in a negative electrode and the group of -SO3 works as cation exchange resin. NO3 and NO2 are re pulsed from the -SO3 group and the movement of NO3 and NO2 on the surface of the negative electrode and inside is substantially restricted. This action is employed for the negative electrode in the title. For example, 2wt.% of a poly ethylene powder treated with a sulfon acid is added to the powder of a cadmium oxide having an average grain diameter of 1mu and kneaded with the addition of an ethylene glycol solution, thereby obtaining a paste state product. Then, this product is applied to a nickel plated steel plate with an opening as a conduc tive support material and subjected to a drying process for 30 minutes for use as an electrode. In this case, for the sulfonation of the polyethylene powder, the powder is immersed about five minutes in a 20% fuming sulfuric acid at 40 deg.C.

Title: Fuel feed controllng method in time of acceleration of internal-combustion engine
Inventor: YAMATO AKIHIRO
IPC: F02D41/10
Filed: 1982-05-20
Abstract: PURPOSE:To aim at improvement in the acceleration performance at low engine speed bounds, by feeding an increased fuel quantity in a way of synchronizing a control pulse signal, in the case where engine speed is below the specified speed and throttle valve opening speed is beyond the specified value. CONSTITUTION:The opening of a throttle valve at the time of both top dead points this time and the last time is found with steps 2 and 3. That whether it is below the specified engine speed or not is judged with a step 4. If it is of low engine speed, valve opening speed DELTAthetaA of the throttle valve is found with an equation thetaA-1-thetaA with a step 6, judging the acceleration. When it is detected to be at quick acceleration in time of low engine speed with these steps 4 and 6, an accelerating increment pulse commensurate to the throttle valve opening speed is outputted with steps 8-10 by synchronizing a control pulse. Hereat, the synchronous pulse is of constant frequency one that does not synchronize a top dead point signal. With this, acceleration efficiency at low engine speed bounds is well improved.

Abstract: PURPOSE:To receive data sent from a moving station passing a zone boundary in a zone before the zone boundary on the ground by installing a leakage coaxial cable (LCX) overlapping the zone boundary. CONSTITUTION:In the case where a moving station 6 moves from a zone (a) in the direction of a zone (b), if the station is running in the zone (a), the station receives radio waves from the ground from an LCXa-1, and if the station moves to the zone (b), it receives from an LCX1b, and receiving is not made from an LCX1a-2 due to a band blocking filter 10. Accordingly, if the content of transmission of the zone (a) is made the same with that of the zone (b), the content of data transmission from the ground can be transmitted to the train without omission. In the case where the moving station 6 is close to the zone boundary and makes transmission, messages such as data, etc. can be transmitted to the central device 5 through LCX1a-2, a ground transmitter-receiver 2a and an approach cable 3a during the time required for zone tracking.

Abstract: PURPOSE:To reduce the movement of an optical element and to perform speedy optical sanning by moving at least one optical element in an image formation optical system in the direction perpendicular to the optical axis and forming a slit scanning image on both a surface to be scanned and a conjugate surface. CONSTITUTION:The 1st surface 1 and the 3rd surface 3 are used in common to a lens 5 by an image magnification and a lens 4 for image reduction and the 3rd surface 3 and an image formation surface 2 are also used in common by the lens 5. When a point Q at the distance L1 from the optical axis of surface 1 is scanned by moving the lens 5 by distance DELTAh2 in the direction perpendicular to the optical axis, the condition DELTAh2<1/2.L1 is satisfied if the variable magnification ratio beta image-formed on the surface 2 is 0<beta<1. When comparing this optical system with the case that the image formation optical system formed by an optical element is moved by distance 1/2L1 to form an image equal to the original one, the movement of the optical element is reduced and the slit scanning magnification changing image is formed speedy. When plural optical elements are moved, the same result is obtained.

Abstract: PURPOSE:To make correct the reading of information and to make small the unit in size, by setting the optical path length between the end of the semiconductor laser and the recording surface of the recording carrier to a given value, in the optical information reader using the self-coupling effect of semiconductor laser. CONSTITUTION:The light beam of the semiconductor laser 1 is made to parallel beam at the collimator lens 3, it is condensed in the recording carrier at the condensing lens, and the reflection beam is fed to the light detector 6 via the laser  active layer 2. In such a unit, since the end surface 1a of laser and the recording  surface constitute the external resonator, the condensing lens and the recording  carrier can be replaced with the flat reflection mirror 7. The effective reflection  factor DELTARN of the multiplex longitudinal mode resonance laser light in the resonator  of L in length changes periodically and is small at the regions of A, B, C.... Since  the positions are a multiple of the product between the refractive index of the active  layer of semiconductor laser and the laser length, the reading is made accurately by  selecting L for the value, because the effect of interference due to return effect is suppressed, and the unit can be made small in size.
