IPC: G01N9/04
Filed: 1980-10-27
Abstract: PURPOSE:To measure the specific gravity of process liquid continuously and automatically, by keeping the volume of the liquid entered measuring pipe by a siphon mechanism constant and measuring its weight continuously. CONSTITUTION:A liquid 3 is collected in a measuring pipe 2 successively by supplying the liquid 3 from a supply pipe 1. When a water level A in a supply side straight pipe 21 of the liquid 3 is exceeded a maximum water level B obtained at the upper S-shaped crooked part, the liquid 3 flows out and nearly the whole quantity of the liquid 3 flows out by a siphon mechanism. When discharge of the liquid is finished, the liquid 3 from the pipe 1 is collected in the pipe 2 successively. The pipe 2 is placed and is fixed to a weighing stand 5 of a weight balance 4 and the weight variation by the increase and decrease of the liquid is converted into an electric signal by a transducer 6 and said signal is sent to a display device 7 and a recorder 8. Only the maximum value is recorded and displaying and recording value can be expressed as the specific gravity by calculating it.

Title: Computing method for contact rate of heat exchanger cooling fin
Inventor: YAMADA MAKI
IPC: F28F1/10
Filed: 1980-10-27
Abstract: PURPOSE:To decide the condition of contact between fins and a wall surface by finding the frequency at which sound pressure generated when the cooling fins fitted to the wall surface of a heat exchanger are flipped with a plate-like stick elastically nearly an right angles is maximized. CONSTITUTION:A sound generated when a cooling fin 1 provided to the external wall of a cooling pipe 2 is flipped with a stick 5 elastically in the nearly prependicular direction is acquired by a microphone 6 and analyzed by a frequency analyzer 7  to find maximum sound pressure. The correlation between a frequency corresponding  to the peak value of a sound pressure level and the contact rate between the fin  and pipe wall is found previously. Consequently, the quality of products is decided  nondestructively and easily by measuring the frequency.

Title: Scanning optical system
Inventor: ITOU MICHIO
IPC: G03G15/04
Filed: 1982-08-30
Abstract: PURPOSE:To eliminate the unevenness in the quantity of light and the adverse influence of interference fringes by providing an arc-shaped filter to which the respective deflected luminous fluxes are made incident at an equal angle between a deflection means for an optical scanning system and the surface to be scanned. CONSTITUTION:An arc shaped filter 16 is disposed between a polygonal mirror 14 and a surface 15 to be scanned. Since the respective scanning light 13 subjected to a deflection effect with the mirror 14 are made incident roughly perpendicularly to the filter 16, there are no differences in optical path length between the adjacent luminous fluxes and the generation of an interference effect is obviated. If the thickness of the filter 16 is maintained uniform, the optical path lengths of the luminous fluxes past the filter 16 are made equal and therefore the generation of the unevenness in the quantity of light on the surface to be scanned is obviated. The unevenness in the quantity of light and the adverse influence of interference fringes are thus eliminated by the simple constitution.

Title: Exposure method of copying device
Inventor: FURUICHI YASUSHI
IPC: G03G15/043
Filed: 1984-07-20
Abstract: PURPOSE:To make the precopy mode for exposure start unnecessary and to extend an triboelectrification area to reduce the applied voltage and to make a device small-sizes, simple, and high-precision by performing image exposure in the triboelectrification area. CONSTITUTION:A wire 7 for primary charging and a converging optical transmission body array 4 for image exposure are arranged in parallel in one casing 6, and image exposure is performed in the triboelectrification area in the Carlson process. Therefore, the precopy mode for exposure start is unnecessary because primary charging and image exposure are performed approximately simultaneously, and the number of primary charging wires 7 is increased because the triboelectrification area around a photosensitive body 5 can be extended. Thus, spot stain in the joint part of the photosensitive body is reduced because the applied voltage is reduced. Further, the device is made small-sized, simple, and high-precision.

Title: Facsimile receiving system
Inventor: TSUCHIYA MASAYUKI
IPC: H04N1/21
Filed: 1995-06-19
Abstract: PURPOSE: To make loads on all of the terminal equipments uniform regardless of the number of installed terminal equipments by allowing a master facsimile server to manage concentratingly a recognition result file and an image file corresponding to the recognition result file. CONSTITUTION: Since a recognition result file 12 and an image file 11 are managed concentratingly by a master facsimile server 1, image information received and result of recognition recognized by a slave facsimile server 2 are all collected by the master facsimile server 1, in which they are unifiedly managed. Furthermore, even when a large number of terminal equipments 3 for confirmation correction are connected to the master facsimile server 1, the master facsimile server 1 makes service of confirmation correction without distinguishing the terminal equipments. Thus, so long as document data not confirmed yet are in existence in the recognition result data, the master server 1 makes confirmation correction processing of the document data not confirmed of any terminal equipment 3 among the plural terminal equipments 3.  Thus, a problem of an unbalanced load on the operator depending on the terminal equipments 3 is eliminated.
