Title: Stationary type hologram scanner
Inventor: MIKAMI IZUMI
IPC: G06K7/12
Filed: 1985-06-12
Abstract: PURPOSE:To reduce the thickness of a housing at the operator side and to enable the operator to handle a hologram scanner in his/her seated position, by distributing primary optical parts at the side opposite to the operator side in the housing. CONSTITUTION:A light beam 2 delivered from a laser oscillator 1 goes toward a beam splitter 22 via a mirror 20 and a lens 21. Thus the reflected beams of three steps are obtained in time division in response to the revolving speed of the splitter 22. Each reflected beam is made incident on a prism mirror 23 for reflection and transmission and reflected by each mirror 24. This reflected beam passes through the opening of a perforated mirror 25 and is made incident on a hologram lens set on a hologram disk 7. The part of the hologram lens is stored in a step part 31c of a housng. The light beam diffracted by the hologram lens is reflected by a mirror 26 and condensed by a reading window 27 to be scattered after hitting a bar code. These scattered beams 28 reverse the route of the beam 2 and are made incident on the hologram lens. Then the beams 28 are reflected by the mirror 25 and condensed on a photoelectric converter 29 to be converted into electric signals. The thickness of the housing is reduced at the area between the hologram disk and the window 27.

CONSTITUTION: Some imaginary strips 54, 55 having equal width (dx) and extending in an auxiliary scanning direction 14 are provided. The surface of a photosensitive medium having the width (dx) permitting the passage of the strip 54 receives light only during a cycle wherein an LED 48 is activated and the surface of the medium is present at the position opposed to a zone 56.

This relation is applied to all of the arbitrary imaginary strips having the width (dx) and the respective arbitrary surfaces in the exposure part of the photosensitive medium receive a strictly same quantity of light. This equal light distribution is shown by a curve 61 and the quantity of light is equal to the min. value Lmin.

Title: Waste liquid treating device for automatic developing machine
Inventor: FUJIMOTO HIROSHI
IPC: C02F1/00
Filed: 1986-06-04
Abstract: PURPOSE:To reduce maintenance expenses and the cost of equipment by incorporating a waste liquid treating chamber adjacently to the drying chamber of an automatic developing machine and using the heat from the driving chamber to concentrate or solidify a waste liquid. CONSTITUTION:The waste liquid is sent to a waste liquid treating chamber 17 through a waste liquid pipe 32 and is dropped onto a brush 54 from the aperture 57a of a pipe 57. Since the heat from a drying chamber 16 is transmitted to the waste liquid treating chamber 17 to supply a hot blast to the chamber 17, water is evaporated when the waste liquid is dropped to the brush 54, and solid matters are stuck to the brush 54. Most of solid matters stuck to the brush 54 remains on the brush as they are though a part of them is dropped naturally, and a cover 58 is opened and the brush is drawn through hands to gather solid matters in a receiving box 35, and the cover 58 is opened to replace the old brush 54 with a new one. Thus, a rotational heat cylinder or the like is eliminated to simplify a structure, and a special heat source is eliminated, therefore, maintenance expenses are reduced.

Title: Failsafe thermostat
Inventor: TAKEDA HIDEAKI
IPC: H01H37/54
Filed: 1994-06-10
Abstract: PURPOSE:To protect a circuit even if a contact of a thermostat is welded by separating one movable contact from a fixed contact in an elastic plate having a pair of movable contacts. CONSTITUTION:When temperature is low, a fixed contact 1b is in contact with a movable contact 6 and a fixed contact 2b is in contact with a movable contact 7, and current flows through a terminal 1a, a fixed plate 1, the fixed contact 1b, the movable contact 6, an elastic plate 4, the movable contact 7, the fixed contact 2b, a fixed plate 2, and a terminal 2a in order. When temperature is raised higher than a set temperature, the curvature of the shape of a bimetal plate 8 fixed to the elastic plate 2 is reversely turned, and since the spring power of the elastic plate 4 is lower on the movable contact 6 side than that on the movable contact 7 side, the elastic plate 4 on the movable contact 6 side deforms and the movable contact 6 separates from the fixed contact 1b to open a circuit. When temperature becomes lower than the set temperature, the elastic plate 4 deforms and the movable contact 6 comes in contact with the fixed contact 1b to close the circuit. Even if the contact of a thermostat is welded, the circuit is surely controlled.

Title: Current command clamping circuit of power converting device
Inventor: ISHIGURO MASAHARU
IPC: H02M7/48
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to control an output current in accordance with a command even if a current command value is being clamped. SOLUTION: When a current command value iv* exceeds a clamp value, the output iv**(=b) of a function generator 2b becomes iv**= iv*-Δiv*=-(a+c)-Δiv*. Thus, the output d of 1/2 circuit 12 becomes d=(a+iv**+c)/2=-Δiv*/2. Therefore, each output iu**, iv** and iw** of a clamp circuit 10 becomes iu**=a-d=a+Δiv*/2, iv**=-(a+ c)-Δiv**, iw**=c-d=c+Δiv*/2 respectively. In this instance, the total output (iu**+iv**+iw**) of the clamp circuit 10 becomes zero and cuts the zero-phase current included in the current commands iu**, iv**, iw**. As a result, even when current commands iu*, iv*, iw* are clamped, the three-phase condition (total of three phases becomes zero) always holds so that output currents iu, iv, iw are controlled in accordance with the commands.
