A replaceable ribbon cartridge for printers is disclosed and which has a user controllable re-inking capability. The cartridge includes both an ink transfer roller and a drive roller, both of which contact the advancing ribbon during printing operations. Also, a re-inking roller is provided, and the re-inking roller is laterally moveable so as to permit the user to selectively move the re-inking roller to a neutral position wherein it has no substantial contact with either the ink transfer roller or the drive roller, to a first operative position wherein the re-inking roller is in substantial contact only with the ink transfer roller, or to a second operative position wherein the re-inking roller is in contact with both the ink transfer roller and the drive roller.

A homokinetic universal joint having an outer ring formed in its inner surface with three axial track grooves, a tripod member inserted in the outer ring and having three legs, and guide blocks pivotally and axially slidably mounted on the respective legs and received in the respective track grooves. The guide blocks are formed in each side thereof with a ball circulating passage having straight raceways. A plurality of balls are rollingly received in each ball circulating passage. The track grooves are formed at both sides thereof with raceway grooves extending parallel to the axis of the track grooves to guide the balls along the straight raceways.

A liquid pressure control device for an anti-lock brake system is provided. The device includes a control valve which intermittently interrupts the liquid pressure feed from a master cylinder to a wheel cylinder, a liquid pressure control piston which moves in such a manner as to control the liquid pressure to the wheel cylinder, a differential pressure-responding member which closes the control valve and moves the liquid pressure control piston in conjunction with its forward motion, a stopper arranged engageably with the differential pressure-responding member located in its initial position, and a gas pressure chamber and liquid chamber, which produce the pressure difference acting on the differential pressure-responding member. The gas pressure chamber is charged with gas, the gas pressure of which is used to return the differential pressure-responding member to its initial position during the non-braking and normal braking condition, while the liquid chamber receives an input of controlling liquid pressure which acts against the gas pressure in the gas pressure chamber during the anti-lock action, so as to make the differential pressure-responding member shift forwards. During non-braking and normal braking conditions, the stopper is engaged with the differential pressure-responding member to inhibit its forward motion and disengaged therefrom during the anti-lock action, so as to allow its forward motion.

A calendar mechanism of a timepiece includes a date indicator having a date wheel portion provided with a notched portion. An operation lever attached to the date indicator is pivotable between a pre-feed allowing position, where a tooth-shaped engaged portion thereof is inserted into the notched portion whereby excess feeding of the date indicator is possible, and a normal feed allowing position, where the tooth-shaped engaged portion retreats from the notched portion whereby normal feeding is possible. The date indicator is rotated by a day earlier than the normal feeding when set to the pre-feed allowing position. A driving lever structure includes a cam follower engaged with a month cam and is driven in response to rotation of the month cam to allow the operation lever to be pivoted between the normal feed allowing position and the pre-feed allowing position.

To provide a calendar mechanism equipped timepiece which, being small and thin, includes two date indicators configuring date characters which are large and easy to see. A calendar mechanism equipped timepiece of the invention includes a first date indicator which displays the ones column of the date, a second date indicator which displays the tenths column of the date, and a program wheel which enables each of the first date indicator and second date indicator to rotate intermittently. The program wheel includes program wheel teeth, first date indicator advance teeth, second date indicator advance teeth having provided at the leading ends thereof second date indicator advance fingers, and correction teeth. A configuration is such that the height of the second date indicator advance teeth is greater than the height of the first date indicator advance teeth, and the height of the first date indicator advance teeth is greater than the height of the correction teeth.

An optical processing apparatus that is capable of detecting accurately the sticking status of deposits sticking to optical means in a background of same color as deposits, preventing occurrence of defective soldering due to feeding failure of wire solder, and detecting solder failure when the leading end portion of the wire solder does not reach up to the processing area. This optical processing apparatus comprises light energy output means for producing light energy, a first optical path for guiding the light energy into a work, optical means disposed in the first optical path for shaping the light energy, a second optical path sharing part of the first optical path for guiding the light from the work to photo receiving means, and driving means for changing the relative positions of at least the optical means and the work.

Provided is a light processing apparatus which can judge goodness or badness of small amount and various kind processing, and is useful for small amount and various kind processing, and can realize light processing at an appropriate position in conformity with a state of a substrate, at low cost, and can prevent production of a bad item before it happens, and enables local heating by focusing light energy, and is useful for a processing apparatus such as solder joint or heat processing of resin and a production equipment which used this. A state of an object to be processed enters into an image receiving unit, through a first light path and a second light path. This image and an image which was set up in a storage device in advance are compared, and goodness or badness judgment is carried out. There occurs a change of a point to be irradiated, in an approximately horizontal direction to the first light path, between a case that the object to be processed is in a warp age state, and a case that it is not so. The change is read as a change of an image shooting position of reflected light by the image receiving unit. It is possible to realize error stop of processing, by a level of a change amount, and to prevent processing bad item production before it happens.
摘要:
There is realized a multifunction timepiece constituted to be able to constitute a plurality of types of hand operating train wheels by only changing positions of integrating parts without changing dimensions and shapes of parts of a movement.A movement of a multifunction timepiece includes a first train wheel rotation center, and a second train wheel rotation center. A train wheel for indicating calendar information is arranged to be rotatable relative to one of the first train wheel rotation center, and the second train wheel rotation center. When the first train wheel rotation center is arranged with a train wheel for indicating calendar information, the calendar information can be indicated by a small hand rotated to move by the train wheel, when the second train wheel rotation center is arranged with a fan shape hand operating train wheel for indicating the calendar information, the calendar information can be indicated by a small hand moved in a fan shape operating train wheel.
