Title: Paper separation mechanism
Inventor: KODAMA HIDEAKI
IPC: G03G15/16
Filed: 1993-12-21
Abstract: PURPOSE:To obtain a paper separation mechanism separating paper without damaging a paper carrier with simple constitution by providing a pressing member exerting force from the inside of the paper carrier and pushing up film, and a separation pawl elastically press-contacting with the surface of the film and pushing down the film from the outside of the paper carrier. CONSTITUTION:This mechanism is constituted of the pushing-up member 16 pushing up the film 19 from the inside of a transfer drum 50 and the separation pawl 8 pushing down the film 19 from the outside of the drum 50 and separating the paper from the film 19. In the case of separating the paper from the drum 50 rotating while electrostatically attracting and holding the paper, the drum 50 is pushed up by the member 16 exerting the force from the inside of the drum 50. At the same time, the drum 50 is pushed down by the pawl 8 elastically press-contacting with the surface of the drum 50, so that the surface of the drum 50 is deformed. After the pawl 8 enters in a gap made by the deformation, it is turned and scoops the paper, thereby separating the paper from the drum 50.

Title: Dc power supply equipment
Inventor: IMAI MINORU
IPC: H02J1/00
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To permit output at the same current proportion, by connecting predetermined resistors in series after converting into a voltage level at a transmitting side where the load factors become the same, and a receiving side converts into a voltage level where the load factor balances each other in response to a power supply module and then supplies the voltage between CB terminals connecting dissimilar power supply modules. SOLUTION: A current balance transmitting section 51 detects a potential difference between both ends of a small resistor R1 inserted between a negative side power supply terminal and an external negative side connecting terminal of power supply modules PM1a to PM1c, as a DC voltage signal proportional to the output current by using a differential amplifier 11. This detected signal is amplified to a voltage V2 as load factor information of the power supply module by using an amplifier 12. Here, a predetermined resistor R2 is inserted between the output end and CB terminal of the amplifier 12. Next, a current balance receiving section 52 amplifies the voltage V2 from the external CB terminal with an amplifier 13 to the predetermined amplification factor where the load factor becomes the same between the dissimilar power supply modules.  Then, this voltage V1 is supplied to the CB terminals CB1a to CB1c of the power supply modules PM1a to PM1c.

Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device which can be easily mounted and has many terminals (leads) and a semiconductor device which can restrain deformation of a semiconductor device caused by temperature change, in a BGA(ball grid array) type semiconductor device. SOLUTION: A substrate 3 on which a semiconductor element 1 is mounted is clamped by metal molds 7 and 8 from above and below, in a resin sealing process. In the metal molds 7 and 8, a protrusion 7a and a recess 8a are formed, respectively, at positions corresponding to outer electrodes 4a.

The resin 5 is injected from a resin injection inlet 9, and cured by heating at a specific temperature for a specific period. When the metal molds 7 and 8 are removed, a semiconductor device sealed wtih the resin 5 wherein the outer electrodes 4a are exposed from the resin 5 is obtained. Finally, metal bumps 6 are formed on the outer electrodes 4a.

Filed: 1988-12-23
Abstract: PURPOSE:To improve the absorption performance of an absorber by forming at least a part of the absorber of a cellulose sponge and increasing the density of the cellulose sponge gradually from the upper layer to the lower layer. CONSTITUTION:A surface material 1 having the sufficient through-holes to allow the passage of moisture, such as bodily fluid, is used. While a leakproof material 2 can be constituted of paper subjected to a polyethylene lamination treatment, etc., or a non-woven fabric, etc., a porous material having moisture permeability is preferably used in order to prevent moistening. The density of the cellulose sponge sheet 4 constituting the absorber 3 is lowered toward the upper layer part. The bodily fluid is rapidly absorbed through the upper layer part of the small density into the absorber 3 in this way and is gradually penetrated and diffused into the lower layer of the large density. The bodily fluid is mainly held in the lower layer part of the large absorption capacity. The bodily fluid absorption rate of the above-mentioned absorber 3 is extremely high and since the absorbed bodily fluid is held in the lower layer part of the absorber 3, the reversion thereof is hardly generated.

Abstract: PURPOSE:To improve the learning effect by showing a desired pattern to be learned and a signal not to be outputted to learn the distance from a signal to be outputted and then giving the pattern to be learned to shown a teacher signal to be outputted for execution of the learning. CONSTITUTION:In a learning step 1 the distance between a desired pattern to be learned and a signal which is outputted by giving a signal not to be outputted to the pattern is learnt via a learning device.
