A copying machine wherein a developing device is provided with a first sensor for detecting the toner density in a developer and a second sensor which is provided around a photosensitive drum for detecting the amount of deposited toner on a test pattern. The toner supply is controlled according to a result detected by the second sensor. When the toner density is judged high from a result detected by the first sensor, a developing bias voltage is set high by a computer, and when the toner density is judged low, the developing bias voltage is set low.

A screw-drive conveying apparatus has on a conveying traveling body side, a first driven roller pair having a shorter distance between two driven front and rear rollers and a second driven roller pair having a longer distance between two driven front and rear rollers. A first screw shaft row with which the respective driven rollers of the first driven roller pair are engaged and a second screw shaft row with which the respective driven rollers of the second driven roller pair are engaged are provided on a traveling path side. The length of screw discontinued spaces between both screw shaft rows is equal to the distance between the driven rollers of the driven roller pair engaged with the screw shaft row on the upstream side.

A circuit module and a manufacturing method for the same, reduce a possibility that a defect area where an electrically conductive resin is not coated may occur in a shield layer. A mother board is prepared. A plurality of electronic components are mounted on a principal surface of the mother board. An insulator layer is arranged so as to cover the principal surface of the mother board and the electronic components. The insulator layer is cut such that grooves and projections are formed in and on the principal surface of the insulator layer and the insulator layer has a predetermined thickness H. An electrically conductive resin is coated on the principal surface of the insulator layer to form a shield layer. The mother board including the insulator layer and the shield layer both formed thereon is divided to obtain a plurality of circuit modules.

A user terminal is connected through the Internet to a server. On the basis of the identification information of the client inputted from the client terminal, the server extracts an service selected by the client from a database for user management, further, extracts calculated maintenance contents for each service from a database for service management and sends them to the user terminal. Thus, the user can collect maintenance contents, such as the staff capable of providing service, the time until the user receives a service, and the charge, so that the user can utilize the information as indications to select an optimal service such as maintenance.

In an image reading apparatus, a white reference member for obtaining a reference value used in shading correction in the reading mechanism and an elastic member for cleaning a surface of the transparent member are provided such that respective positions of the white reference member and the elastic member with respect to the transparent member are variable. A controller controls the positions of these members with respect to the transparent member to alternately achieve movement of the white reference member to a position where the white reference member faces the transparent member and movement of the elastic member to a position where the elastic member faces the transparent member. The controller calculates the above reference value using a plurality of detection values read by the reading mechanism through the above positional control.

[Problems] There are provided a chip separation method and a chip transfer method using features of dry etching.[Means for Solving the Problems] In the chip separation method, a multiple number of semiconductor devices or semiconductor integrated circuits are separated from a wafer 100 on which the multiple number of semiconductor devices or semiconductor integrated circuits are formed. The method includes forming, on a surface of the wafer 100, a mask layer through which a line-shaped pattern to be removed for separating the semiconductor devices or semiconductor integrated circuits is exposed; and etching the exposed pattern to a depth equal to or larger than about ⅔ of a thickness of the wafer. One group of separated semiconductor devices or semiconductor integrated circuits has a distinguishable shape from another group of separated semiconductor devices or semiconductor integrated circuits.

A computer terminal connected to a manufacturing apparatus as an object of the maintenance management is connected to a server machine providing a maintenance management service by a network, enabling bi-directional communication. The computer terminal monitors whether or not the object apparatus is restarted and transmits restart information indicating restart completion due to maintenance performed on the object apparatus by the customer to the server machine upon determining that the object apparatus is restarted. The server machine generates a random number within the specific range when receiving the restart information from the computer terminal, retrieves points corresponding to the random number from the lottery point setting storage unit, and stores the retrieved points in the lottery point storage unit. This can encourage the customer to perform maintenance on the object apparatus in order to indicate said restart completion to obtain more points.
