Title: Video information compressing and encoding device
Inventor: KUMANO MAKOTO
IPC: H04N19/60
Filed: 1992-02-21
Abstract: PURPOSE:To improve compressing and encoding effects as a whole without increasing circuit scale by encoding an AC low frequency part together with a DC while using the same encoder, and concentrating the generating distribution of an AC high frequency part. CONSTITUTION:Video information data are inputted to a terminal 1, discrete cosine-transformation is executed by an orthogonal transformer 8, and an AC coefficient high frequency part output 91 is encoded by a first encoder 21. On the other hand, a DC coefficient AC coefficient low frequency part output 92 is encoded by a second encoder 22. Thus, the compressing and encoding effects can be improved by executing an encoded output at the encoder 21 exclusive for the AC high frequency, encoding the AC low frequency part together with the DC at plural encoders and comparatively selecting the minimum code among respective outputs.

Title: Developing device
Inventor: OKAMOTO YUKIO
IPC: G03G15/09
Filed: 1983-03-05
Abstract: PURPOSE:To prevent fogging and improve picture quality by a bias voltage within a specific range to between the base body of a photosensitive body and a toner carrier, and expanding the allowable range of the background voltage of the photosensitive body. CONSTITUTION:The bias voltage VB shown by an expression is impressed to between the base body 38 of the photosensitive body 10 and a developing sleeve 13 as the toner carrier. Consequently, an actual development starting voltage V0' becomes V0'=V0+VB; when the potential VW of the background part is positive, the VW has the wide spreaded allowable range extending almost from a minimum VB-V0 to a maximum V0+VB. Therefore, the area wherein fogging does not occur is widened by the bias VB' so even if the VW varies owing to the characteristic variation with the temperature of the photosensitive body, etc., the variation is absorbed to enter a fogging-free state all the time, thus improving the picture quality.

Abstract: PROBLEM TO BE SOLVED: To solve the problem of non-conformity that the circumference of a pump is under water when a temperature sensing valve is opened by providing the temperature sensing valve which is opened upon sensing the temperature of water within a cooling water circulating passage, concurrently providing the aforesaid valve for the water delivery part of a water pump, and thereby connecting the outlet port of the temperature sensing valve with the downstream side of the valve device. SOLUTION: When a water pump 1 is driven with a water cooling engine 2 driven, water is sucked in out of a water feed source 10 so as to allow pressure within the water pump 1 to be increased, and water within the water pump 1 is fed to the water cooling engine 2 through a water delivery part 1b and a feed side passage 5a, so that the inside of the water cooling engine is thereby cooled. Water after cooling has been done, it is circulated to the water absorption part 1c of the water pump 1 out of a discharge side passage 5b through a cooling water circulating passage 7. Therefore, when a valve device 3 connected with the water delivery part 1b is kept closed, cooling water is repeatedly circulated within the cooling water circulating passage 7, so that it is thereby increased in temperature. Therefore, when the temperature of cooling water comes up to a set temperature, a temperature sensing valve 4 is opened, and cooling water is so designed as to be forwarded to the downstream side of the valve device 3.
