IPC: G03B3/00
Filed: 1986-05-12
Abstract: PURPOSE:To correct the position of a photographic optical system without raising the cost neither requiring a space by adding a detecting means which senses insertion/ removal of an optical element to a control means to correct the focal length in accordance with insertion/removal of the optical element. CONSTITUTION:A correcting device where an optical element 3 like a soft focus filter can be inserted to and removed from the photographic optical path of a photographic optical system 1 is provided with a detecting means 20 which senses insertion/removal of the optical element 3 and a control means 10 which controls the extent of correction of the position of the photographic optical system in accordance with the variance of the optical path length due to insertion/removal of the optical element 3.

Title: Optical ppm synchronizing signal
Inventor: SUGIYAMA HISAYOSHI
IPC: H04B10/00
Filed: 1987-05-01
Abstract: PURPOSE:To establish the word synchronization at the reception side without deteriorating the transmission efficiency by providing a specific transmission region sending an optical pulse for each signal block and sending a signal block not inserting an optical pulse to the said transmission region as a head block constituting a word. CONSTITUTION:Seven time slots among ten pieces of time slots 2 constituting a signal block are used as the transmission region and the remaining three are used as the inhibition region 5. It is decided in advance between a sender and a receiver that no optical pulse 6 is to be sent in the transmission region 4 in the first block. Then each signal block is split into the transmission regions and the inhibition regions and the head block at the receiver side is identified by selecting the region sending the optical pulse, resulting that the word synchronization is taken. Thus, it is not required to send a signal different from an information signal such as an optical pulse representing the synchronizing pattern and the word synchronization of the receiver side is established without deteriorating the transmission efficiency.

Title: Production of optical thin film
Inventor: ITOU SEIJI
IPC: G02B1/10
Filed: 1978-09-04
Abstract: PURPOSE:To form a homogeneous optical thin film without causing a fractionating effect by frranging equally or unequally a plurality of vacuum-deposition materials with different refractive indexes on a stage and by turning the stage to successively irradiate the materials with electron beams and to evaporate the materials while always stabilizing the evaporation. CONSTITUTION:Vacuum-deposition materials with different refractive indexes, e.g. TiO212a and MgF212b are arranged in crucible 10 on a stage to be irradated with electron beams (d). Next rotary stand 9 is turned to successively irradiate materials 12a, 12b with beams (d), whereby the materials are evaporated and deposited on sample substrate 4 and film thickness monitoring substrate 7. By this method the materials are evaporated with single electronic gun filament 11, so stable vapor currents are scattered from evaporation source 2. Since the materials are successively irradiated with electron beams, they are evaporated almost simultaneously and deposited on substrate 4, causing no fractionating effect even if they are different in vapor press.

Abstract: PURPOSE: To restrain the deterioration of capacity due to the adhesion of levitating dust in a heat exchanger equipped with reticulated fins. CONSTITUTION: An air filter 2 is divided into a heat transfer tube coping unit 2a and a fin coping unit 2b while the mesh of the filter for the heat transfer tube coping unit 2a is made rough and the mesh of the filter for the fin coping unit 2b is made fine to provide a difference in the levitating dust collecting capacity between the heat transfer tube coping unit 2a and the fin coping unit 2b whereby much of levitating dust is collected in the fin coping unit 2b and the amount of levitating dust arriving at the fin unit 1b of a heat exchanger 1, positioned at the downstream side of the fin coping unit 2b, is reduced thereby preventing the adhesion of the levitating dust to the fin unit 1b as much as possible.  On the other hand, in the heat transfer tube coping unit 2a, the volume of collected levitating dust is small in addition to a low flow resistance in this part originally whereby the flow resistance in the air filter 2 can be minimized in spite of the adhesion of the levitating dust and the deterioration of introducing volume of air into the heat exchanger 1 can be restrained. As the synergism of these facts, the air-conditioning capacity of the air conditioner Z can be maintained excellently for a long period of time.
